Coronavirus's next victim: Big Meat
(Grist) Nathanael Johnson, April 30
“It's going to cause price spikes somewhere downstream,” said Rich Sexton, an agricultural economist at the University of California, Davis. But the average shopper might only notice empty shelves rather than higher prices, because “big grocery chains don't like to jack up prices, especially in times like this.”
…“There is going to be even more of a rush to automate farmwork and slaughterhouses,” Sexton said.
As meat plants idle, California has no shortage of fish, dairy
(NBC News) Dennis Romero, April 29
…California produces about 20 percent of the nation's milk and has a large poultry processor in Foster Farms, but is otherwise dependent on the Midwest for pork and much of its beef, according to Daniel Sumner, director of the University of California's Agricultural Issues Center.
The state slaughters dairy cows for hamburger and raises calves for beef. But the 1-year-old livestock is sent to the Midwest for corn and soy feeding before being processed for beef there, he said. "We've never produced any hogs to speak of," Sumner added.
California producers fill nearly half the state's chicken and egg demand, he said.
1-In-4 San Diegans Unemployed From Pandemic, North County Wants Businesses To Reopen, San Diego Sees Drop In Homelessness, And Online Learning Nightmare For Vets
(KPBS Midday Edition) Maureen Cavanaugh and Jade Hindmon, April 29
An estimated 25% of San Diegans are out of work because of the pandemic, according to a new SANDAG report. Plus, a handful of North County mayors want businesses in their towns to reopen sooner rather than later. Also, homelessness in San Diego is seeing a decline, according to the latest homeless count. Also, it's not just young students who are having a hard time with distance learning, veteran students are also dealing with the challenges of virtual classrooms. ...

Virus-related food shortages will be temporary in U.S., experts say
(Farm Press) Tim Hearden, April 29
…“Every economist agrees that the massive hit to the world economy and trade will likely cause millions of very poor people to be out of work and with no income,” said agricultural economist Daniel Sumner, director of the University of California's Agricultural Issues Center. “This is a consequence of the disease, but also of the policy of shutting down the economy.
“In poor countries, when the economy is shut down, the poorest people get even more hungry and people die, especially the kids,” Sumner said in an email.
'We're in pretty good shape' | Northern California unlikely to see meat shortage
(ABC10) Lena Howland, April 29
… Despite the ad Tyson Foods released over the weekend, saying the food supply chain in America is breaking, UC Davis Professor Daniel Sumner said we could expect to see some higher prices, but he doesn't expect to see shelves being wiped out anytime soon.
"If you want to have some very specialized meat product, you may find that in short supply in your local market on the day you're shopping, if you went back the next day, it may be there, but I don't think anybody has to worry about the supply chain in America, we're in pretty good shape," Sumner said.
And he said the only way we will see a shortage is if people panic buy, just like they did with toilet paper.
"As we've learned in the past month or two, you could certainly create a shortage in the sense that consumers can altogether if we all ran out and decided to stock up every freezer space that we have with steaks and pork chops," Summer said.
Nature And The Coronavirus: As Humans Continue Lockdown, Wildlife Creeps Back In

Scientist at work: Trapping urban coyotes to see if they can be 'hazed' away from human neighborhoods
(Conversation) Niamh Quinn, April 29
After weeks of sleepless nights spent scrutinizing grainy images relayed from our remote cameras, mostly of waving grass and tumbling leaves, finally, there it is. A live coyote with a loop around its neck. On October 8, 2019, my colleagues and I caught the first member of the University of California Agriculture and Natural Resources pack, #19CU001.
Coronavirus: Should California brace for a meat shortage? Not exactly, say industry experts
(SF Chronicle) Esther Mobley, April 28
… There's not a shortage, exactly, say industry experts, though interruptions to the supply chain mean that it's taking a little longer than usual for meat to get from a farm to your grocery store shelf.
“We will have a short period where we have fewer packages of meat in the case,” said Daniel A. Sumner, director of the University of California Agricultural Issues Center. It will be an inconvenience, he said: “Let's say you like thin-cut pork chops, I like thick-cut pork chops. Well, one of us will be disappointed if we shop late in the day.”
Carbon Sequestration in Vineyards
(AgInfo) Tim Hammerich, April 27
...However, Extension Specialist Kaan Kurtural and his team at the Oakville Experiment Station are currently evaluating the impact cover crops can have on carbon sequestration in vineyards.
Kurtural…”Growers came to us. A couple of the questions they had was how can we sequester the carbon and how can we mitigate the amount of greenhouse gases we emit from the vineyards? So that was some background work done on it. Cover crops do sequester carbon and will store it in the soil. But as you till them, if you till the row middles, all this stuff is release back into the atmosphere. So we worked with a couple of private companies and we were able to get this new type of cover crop using a perennial system. Meaning that it doesn't have to be tilled or mowed, it just goes dormant. So we're comparing now till versus no-till systems using perennial and annual cover crops. So that's how that began.”
Covid-19 has forced large-scale farms that supply institutions to dump produce they can't sell. Why can't it just feed hungry people ? We've got answers.
(Counter) Lela Nargi, April 27
… To get a clearer understanding of where institutional food comes from, why kinks at the center of the supply chain make rerouting a challenge, and what's being done to change that, I talked to a variety of agriculture experts.
…Dr. Gail Feenstra, deputy director, Sustainable Agriculture Research and Education Program, University of California Davis: Our food system generally is built for global distribution. Now that's suddenly cracked, people are going back to more local food systems, where [important middle-tier components] like storage facilities [for meat and grain] aren't available.
…Feenstra: In California, some new food hubs are starting up to make the connection between small- and mid-scale famers with excess, and consumers who use CalFresh/SNAP. There's also work being done to figure out how to change CSAs to direct delivery or drop-off. Who is making these connections are co-op extension service agents, in every county in the U.S. They can share resources and research, and have access to grant monies. One agent told me she worked with county board supervisors to keep farmers' markets open, then with market managers to reorganize to keep the markets safe.
COVID-19 outbreak causing possible meat shortage across US
(KRON4) Dan Thorn, April 26
…“That doesn't seem to be on the horizon yet… but we have had some disruptions,” Daniel Summer said.
Those disruptions, says Daniel Sumner — a U.C. Davis agricultural economist — will not create a shortage of meat.
Even after the country's largest meat producers including Tyson, along Smithfield and JBS have recently shuttered processing plants.
“You and I may see our favorite supermarket low on something but there will be plenty of meat –beef, pork and chicken that we all like there will be plenty of meat in the supermarkets,” Summer said.
Marin farm sector struggles as virus cripples food services
(Marin IJ) Richard Halstead, April 26
… Randi Black, a University of California Cooperative Extension dairy adviser for Marin County, said, “We're kind of lucky where we are. We haven't been impacted quite as much as some of the eastern U.S. dairies have been. That's where we're seeing a lot of milk dumping.”
Black said that is because processors who buy Marin dairy farmers' milk sell most of their milk to grocery stores, while processors in the east rely more heavily on the food-services industry, which includes restaurants, hotels and airlines.
Want to save your citrus trees? Start a full-fledged insect war
(Los Angeles Times) Jeanette Marantos, April 25
…In citrus-loving California, some 60% of homes already have one or more citrus trees in their yard, said UC Riverside entomologist Elizabeth Grafton-Cardwell, director of the Lindcove Research and Extension Center in Exeter. (That's a statewide average, with fewer in Northern California and more in Southern California, she said.)
…But Mark Hoddle, a biological control specialist at UC Riverside, sees things differently. Hoddle and his entomologist wife, Christina Hoddle, also at UC Riverside, went to Pakistan in 2010 looking for natural enemies of the Asian citrus psyllid, and there they found Tamarixia radiata, tiny parasitoid wasps that lay their eggs on the backs of psyllid toddlers (a.k.a. nymphs).
Even as new technologies revolutionize farming, not everyone has access
(Sac Biz Journal) Emily Hamann, April 24
Technology could hold the key to solving growers' issues both around labor and water.
George Zhuang, a farm adviser with the UC Cooperative Extension, works with wine grape growers in the Fresno region, where machines have largely taken over the job of growing grapes.
“Most newly established vineyards go to 100% mechanization,” Zhuang said.
Amid rising costs and limited availability, farmers struggle to find enough workers
(Sac Biz Journal) Emily Hamann, April 24
…Wine grapes are known for being especially labor intensive. Grape harvesters have been commonplace in vineyards in the San Joaquin Valley for decades, but vines still needed maintenance, including pulling leaves and trimming shoots, by hand. Now that's changing as well, said Kaan Kurtural, viticulture specialist at the UC Davis.
…“We have a lot of consolidation in our business,” Kurtural said. “Vineyards are getting larger as farmers are getting old and their kids don't want to do this anymore, so they're selling their holdings.”
A Strained Food Chain
(Health in all Matters) Michael Joyce, April 24
COVID-19 has drastically disrupted the way food is produced, distributed, and available in the U.S. and around the world. The toll of the virus on those who plant, pick, buy, sell, and, at times, go hungry, is increasing. In this episode, we explore the vulnerabilities of a complex and interconnected food system and the inevitable bright spots along the way.

Farmers face new challenges in their ongoing quest for water
(Sac Biz Journal) Emily Hamann, April 24
…“Almond trees are actually pretty resilient,” said Katherine Jarvis-Shean, a Sacramento-area orchard farm advisor with the University of California Cooperative Extension.
While the trees themselves can live through a drought year, insufficient water will reduce yields for the present season and seasons into the future, Jarvis-Shean said.
But this year growers can also rely on groundwater pumped from wells drilled into a patchwork of underground aquifers.
“One year with low precipitation is not a problem with groundwater,” Jarvis-Shean said. “The problem is if we continue to have dry winters.”
Protecting The Valley's Vulnerable Populations From COVID-19
(KVPR) Kathleen Schock, April 24
COVID-19 is disproportionately hurting vulnerable communities like seniors, ag workers and the homeless. To learn about efforts to protect these at-risk populations, FM89's Kathleen Schock spoke with Lisa Blecker, pesticide safety education program coordinator for the UC Division of Agriculture and Natural Resources, Laura Moreno, chair of the Fresno Madera Continuum of Care, and Kristen Beall Watson, CEO of the Kern Community Foundation.
Too celebratory for a pandemic, California's farmed oysters and caviar lose their markets
(San Francisco Chronicle) Janelle Bitker, April 24
…California's aquaculture industry, which includes farmed trout, clams and mussels in addition to higher-end abalone and oysters, represents about $200 million in annual sales, according to Jackson Gross, an aquaculture specialist at UC Davis.
…“Are people willing to pay for a premium local product?,” Gross said. “They're doing that at restaurants, but they're getting the frozen stuff from the big chain stores.”
Stop stable flies from biting into profits
(Progressive Dairy) Julia Hollister, April 23
It only takes five stable flies biting on the front legs of a cow to reduce weight gains and milk yields, according to Alec Gerry, a University of California – Davis veterinary entomology specialist.
Gerry, who spoke at the 2020 Golden State Management Conference in Modesto, California, has been researching flies for over 25 years. His most recent studies are in collaboration with researchers at the Veterinary Medicine Teaching and Research Center in Tulare, California.
In The Quiet Of Sheltering In Place, Have You Encountered Wildlife Differently?
(KPCC ) Larry Mantle, April 23
As the quarantine continues, residents surrounding Griffith Park have shared that they're noticing more wildlife activity - hawk nests, deer in the hills, opossums on the roads.
According to the Los Angeles Times, some wildlife biologists are saying what's changed isn't animal behavior but our own. We finally have the time and the patience to notice the wildlife around us.
Oakland Schools Use Gardening to Help Families
(KCBS radio) Matt Biglar, April 23
Canned food... diapers... tomato plants?
As KCBS Radio's Matt Bigler reports, Oakland schools are helping families get food and supplies and also get into gardening.
The plant giveaway came out of the Contra Costa Master Gardeners spring fundraiser, which unfortunately withered and died this season.
“But with the shelter in place order, we were unable to hold our plant sale.” Dawn Kooyumjian said, they decided to donate their seedlings to nearly 50 organizations, including Oakland Unified.
“People are able to come, pick up their necessities that the school district is providing, and also take home a vegetable plant that will allow them to have a little bit of food security in their home.
The Great Potato Giveaway
(NPR) Stacey Vanek Smith, April 23
…Daniel Sumner is an agricultural economist at the University of California, Davis. He says the problem boils down to two things.
DANIEL SUMNER: How streamlined and specialized things are.
...SUMNER: The farmer will be linked directly to the restaurant customers and grow for that restaurant in San Francisco or New York City or somebody growing exactly the kind of lettuce that McDonald's needs for their hamburgers. That's been a great system.
Lockdown silver linings: For a Sacramento family, baby chickens bring meaning, solace
(Sac Bee) Diana Williams, April 22
…Imagine my delight in stumbling across a backyard chicken census online. It's overseen by Maurice Pitesky, a veterinarian and epidemiologist at the UC Davis School of Veterinary Medicine-Cooperative Extension.
Pitesky's best guess is there are about 100,000 backyard flocks in California. Sacramento probably has about 11 percent of them, making ours the third-highest backyard chicken region in the state, behind Los Angeles and San Francisco.
Volunteer program donates over 30,000 plants to community gardens in Contra Costa
(KRON4) Omar Perez, April 21
A volunteer program donates thousands of vegetable plants to local undeserved communities in the Bay Area free of charge. Over the last few weeks volunteers for The Contra Costa Master Gardeners Program donated more than 30,000 plants to local school and community gardens.
…“Because of COVID-19 they were not able to have the sale so they quickly decided they would distribute the plants for free to local communities, elderly and schools,” Bay Area Program Director Frank McPherson said.
Coyotes, falcons, deer and other wildlife are reclaiming L.A. territory as humans stay at home
(LA Times) Louis Sahagun, April 21
Similarly, research scientist Niamh Quinn, who serves as human-wildlife interactions advisor for UC Cooperative Extension, said none of the five collared coyotes she is studying in the cities of Hacienda Heights, Roland Heights, La Verne and Chino Hills “have changed their behavior yet.”
“I do believe, however, that human behavior has been altered significantly by the lockdown in ways that are closing the gap between us and what's wild around our own homes — and that's great, up to a point,” she said.
She worries that animals may be pushed into closer conflicts with humans. “We have to interact with wildlife from a distance. That is because we still do not know all the diseases that, say, coyotes and rats carry with them.”
A century later, victory gardens connect Americans again
(AP) Kristin M, Hall, April 21
… Creating a victory garden now can be, as it was during World Wars I and II, a shared experience during hardship and uncertainty.
“World War I, to me, is a pretty stark parallel,” said Rose Hayden-Smith, a historian and author of “Sowing the Seeds of Victory: American Gardening Programs of World War I.” “Not only was there a war, but there was an influenza pandemic.”
… “So these gardening posters and food preservation posters would appear in literally dozens of languages,” said Hayden-Smith....“We don't have poster art, but we have Instagram,” she said.
Empty Grocery Shelves and Rotting, Wasted Vegetables: Two Sides of a Supply Chain Problem
(Inside Climate News) Georgina Gustin, April 19
"In terms of resilience and nimbleness, they seem to be able to pivot and figure out new supply chains quickly," said Gail Feenstra, deputy director of the University of California-Davis Sustainable Agriculture Research and Education Program (SAREP). "They're always struggling because of the competition that comes from the global food system. It puts many of them at a disadvantage. But now that system is in complete disarray. It allows these regional food systems to emerge. They're the ones that are bringing relief to communities."
… "This is more than a dress rehearsal. This is it," said Feenstra, of UC-Davis, referring to the disruptions caused by the pandemic. "This is going to be here for a while and it isn't the last time this will happen. This is an opportunity for our policy makers to invest in small and mid-scale businesses."
Is your tree on death's door? Here's how to tell
(LA Times) Jeanette Marantos, April 19
Climate change, invasive species and even international trade are taking a serious toll on California trees. An estimated 150 million trees died during the drought that started in December 2011, according to Smithsonian Magazine, and the stressed trees that survived became more vulnerable to attack by a host of newcomer pests, said Philippe Rolshausen, subtropical tree specialist for the Cooperative Extension office at UC Riverside.
"There are lots of invasive pests everywhere because of global warming and the movement of plant materials in general," he said.
Fresh Produce and Milk Go to Waste Even as People Need Food Amid Coronavirus Pandemic
(KQED Forum) Michael Krasny, April 16
Even as food banks are seeing more demand than ever, some California farmers are dumping milk and letting produce rot. The coronavirus pandemic has disrupted how we eat and in turn, how food is distributed. The closure of many restaurants, venues, and schools is leaving many food suppliers with excess perishables. Meanwhile, retailers and food banks are scrambling to keep food in stock. We talk with experts about how California's food supply chain has been disrupted, how it's adapting, and what to expect in the months to come.

New studies provide details about trellis type, planting density, cost and potential benefit of vineyard mechanization
The studies estimate the cost of establishing a vineyard and producing wine grapes, focusing on four wine grape varieties – Cabernet Sauvignon, Chardonnay, Rubired and Colombard.
“Those studies take into consideration mechanical pruning, leafing, shoot thinning, and harvest on a typical wine grape vineyard with the average production level for this region,” said George Zhuang, UC Cooperative Extension viticulture advisor in Fresno County.
“With farming labor becoming more scarce and expensive, growers will opt to transition into more mechanization,” Zhuang said. “These studies provide detailed information about the trellis type, planting density, cost and potential benefit of vineyard mechanization. Based on these studies, fully implemented mechanization reduces the production cost from $3,000 to $2,500 per acre and that represents 17% cost reduction. This information will ultimately help growers to guide their production practices to more profitable and competitive ways under the new era of farming labor.”
“The investment to purchase and own equipment can be high,” Zhuang said. “Fortunately, it is easy to find a contractor in this region to perform certain vineyard tasks, if the initial investment to purchase equipment is prohibitive.”
Numerous studies, including UC studies, have confirmed the benefits of vineyard mechanization to grape and wine quality with lower production costs.
“It is a win-win-win situation,” Zhuang said. “Growers can improve their farming margins, wineries and juice processing plants can get reliable and higher quality grapes and juice from farms, and average consumers can enjoy better wine and more healthy grape products at an affordable price.”
The studies are based on 200-acre farms with the vineyard established on 40 acres using two types of trellis systems – quadrilateral cordon system and bilateral cordon system. In addition to regular grape production expenses – such as irrigation, fertilization and pest control – the researchers broke out the differences between machinery costs and hand labor hours required for thinning, pruning and harvesting for each variety.The prices for labor, materials, equipment and custom services are based on October 2019 figures.
Input and reviews were provided by UC Cooperative Extension farm advisors, specialists, grower cooperators and other agricultural associates. The authors describe the assumptions used to identify current costs for wine grape establishment and production, material inputs, cash and non-cash overhead. A ranging analysis table shows profits over a range of prices and yields.
The new studies are:
- 2019 - Sample Costs to Establish and Produce Winegrapes in the Southern San Joaquin Valley – Chardonnay Variety
- 2019 - Sample Costs to Establish and Produce Winegrapes in the Southern San Joaquin Valley –Cabernet Sauvignon Variety
- 2019 - Sample Costs to Establish and Produce Winegrapes in the Southern San Joaquin Valley – Rubired Variety
- 2019 - Sample Costs to Establish and Produce Winegrapes in the Southern San Joaquin Valley – Colombard Variety
All four winegrape studies can be downloaded from the UC Davis Department of Agricultural and Resource Economics website at http://coststudies.ucdavis.edu. Sample cost of production studies for many other commodities are also available on the website.

UC Cooperative Extension, Beckstoffer Vineyards and Duarte Nursery are launching the wine industry's most ambitious cabernet sauvignon rootstock and clone trial in the Red Hills of Lake County to give the varietal greater resilience to climate change.
Cabernet sauvignon is California's second top-selling varietal by volume, just behind chardonnay.
“We have been growing cabernet sauvignon since the 1970s, and we are very proud to be part of this trial, which will help improve cabernet sauvignon growing for years to come,” said Andy Beckstoffer, owner and CEO of Beckstoffer Vineyards, which is providing the land and labor for the project.
The industry-driven trial – “Climate-smart Solutions for Cabernet Sauvignon Production” – includes 3,600 vines with 10 cabernet sauvignon clones on 10 rootstocks.
“This trial will give us data that will help inform and improve growing practices for cabernet sauvignon across the state for the next two decades,” said the trial's lead researcher, S. Kaan Kurtural, UC Cooperative Extension viticulture specialist at UC Davis Department of Viticulture and Enology and Oakville Experiment Station.
While the experimental vineyard is in Lake County at a property known as Amber Knolls, the data will be analyzed in Oakville.
The trial officially launched Aug. 15 in Kelseyville with a celebratory vine planting as Andy Beckstoffer and son David Beckstoffer planted the vine that also marked a milestone – the 1.5 millionth vine for Beckstoffer Vineyards Red Hills. Researchers, industry representatives and journalists gathered to celebrate what is affectionately known as “the mother of all cabernet trials.”
“Everything is wonderful in Lake County – for growing cabernet sauvignon and for doing research,” Andy Beckstoffer said, noting the Lake County region's ongoing support for farming.
Pedro Rubio, Beckstoffer Vineyards Red Hills general manager, said, “Lake County will definitely benefit, but the results from this trial will be very helpful for the whole industry.”
Designed to address resiliency in a changing climate, the trial will examine which combinations give the best results with a focus on drought tolerance and water-use efficiency as well as crop yield and grape quality.
“The idea behind the trial is to gain further insights into the interactive effects of rootstock selections crossed with cabernet clones and the impact of that on water relations and overall sustainability,” said Clint Nelson, ranch manager for Beckstoffer Vineyards Red Hills.
“The trial will give us an understanding of the synergistic relationship of clone and rootstock and what combination drives the best quality and production,” he said.
According to Nelson, the trial will look at canopy architecture, yield components, water relations, traditional fruit chemistries, secondary metabolites such as aroma, mouthfeel and color, as well as overall vine performance.
Duarte Nursery is providing all of the planting material for the trial.
“The diversity of rootstocks and clones chosen for this project includes some of the most modern cabernet sauvignon clones designed for high quality and for production,” said John Duarte, nursery president.
Duarte said the trial is employing a lot of cutting-edge technology and using some of the cleanest plant materials available to prevent grapevine viruses.
“Planting a vineyard with pristine nursery stock initially really extends the life of that vineyard,” Duarte said.
Viticulture has become more data-driven, and this trial will measure a staggering amount of data generated by the 100 or so rootstock-clone combinations over the approximately eight to 10 years of the trial's duration.
“Nothing of this scope has been attempted,” said UC Cooperative Extension specialist Kurtural, who acknowledged logistics as the biggest challenge with planning, data collection and timely analysis being at the forefront of his mind. “It keeps me up at night.”
Planning for the length of the project also is a concern. The vineyard will be planted this year and the first crop will be harvested in 2021. It will take at least six years to begin to see consistent results.
Kurtural said the project will provide research opportunities in academic and applied science for at least two students to complete work toward a doctoral degree in horticulture and agronomy.
Glenn McGourty, UC Cooperative Extension viticulture advisor for Lake and Mendocino counties, is a research collaborator on the project.
“Lake County obviously has an important role to play in fine wine in the North Coast, particularly for cabernet sauvignon,” McGourty said. “And this trial really marks the importance of this location in terms of the commitment and the collaboration that we see here among both public and private sectors.”
About Beckstoffer Vineyards: Named “Napa's most powerful grape grower” by both the Wall Street Journal and Wine Spectator, Beckstoffer Vineyards was founded in 1970. Beckstoffer Vineyards is firmly rooted in the soil of Northern California's wine country, with Andy Beckstoffer playing an integral role in the evolution of the wine grape industry since 1970. Joined at the family-owned business by his son David in 1997, they share a common mission – to produce the highest quality grapes in Northern California that form the foundation for exceptional wines – and a combined passion for the land and viticulture expertise. Beckstoffer Vineyards first acquired land in the Red Hills in 1997, which after subsequent acquisitions, today totals nearly 2,000 planted acres across three blocks: Amber Knolls Vineyard, Crimson Ridge Vineyard, and Amber Mountain Vineyard.
About Duarte Nursery: Duarte Nursery, Inc. (DNI) is a family-owned and operated nursery and the largest permanent crops nursery in the United States.
A major expense in producing winegrapes is labor. Two UC Cooperative Extension experts appeared on the Jefferson Exchange radio program to explain how mechanization of pruning, leaf removal and shoot thinning, combined with mechanized harvesting widely implemented decades ago, will dramatically reduce the need for labor in California winegrape production.
"The minimum wage is going to increase to $15 per hour in 2022," said George Zhuang, viticulture advisor with UCCE Fresno County. Besides, it is getting more challenging for growers to find enough workers due to labor shortages and higher wages in other fields, such as construction.
The machinery for mechanized vineyards requires an investment of about $100,000, said Kaan Kurtural, UCCE viticulture specialist. At that cost, growers begin to break even after a year.
The biggest obstacle to mechanization is the way winegrape vineyards have traditionally been trellised. The cross arms get in the way of machines as they go through the vineyards. In a recent research project by Zhuang and Kurtural, the scientists converted a traditional system to single high wire and managed it with mechanical equipment.
"It was more profitable ... with the same, if not better, quality and value at the farm gate," Kurtural said. "The writing is on the wall for growers to adapt to this as quickly as possible."
Host Geoffrey Riley asked whether the labor savings will result in cheaper wine. Kurtural laughed.
"No," he said. "Wine prices are set by market demand. I don't think wine is an expensive beverage."
CDFA awards grant for Proactive IPM program
(Morning Ag Clips) April 30
The California Department of Food and Agriculture has awarded funding for one project in the initial funding cycle for the Proactive Integrated Pest Management (IPM) Solutions grant program. The project, titled “Proactive Biological Control of Spotted Lantern Fly, Lycorma delicatula (Hemiptera: Fulgoridae)” was awarded $543,936.
The three-year project will develop biological control agents for spotted lantern fly, an invasive pest that has not yet arrived in California but is spreading rapidly across the eastern US. This pest has the potential to affect many high-value California crops including grapes, walnuts, avocados, and pistachios. The project will piggyback on work that is already being conducted on the pest in the eastern US and abroad. Project leads are Dr. Mark Hoddle (UC Riverside) and Dr. Kent Daane (UC Berkeley). The biological control agent is a small (3 mm) stingless wasp, native to China, that parasitizes the eggs of the spotted lantern fly.

If you've ever wondered how a sheep's wool becomes a sweater, you might want to check out the "Barn to Yarn" event in Hopland this weekend. This popular springtime event will return to the University of California Hopland Research and Extension Center this Saturday, May 4.
The Barn to Yarn event will feature farmers and ranches, shearers, spinners, weavers, and knitters, and other local experts involved in the Northern California sheep industry. There will educational activities, presentations, workshops, take-home craft activities, and more for all ages.
Moth caterpillars are back for a rare second bite in the Bay Area
(Mercury News) Cat Ferguson, April 29
…Andrew Sutherland, University of California Cooperative Extension's urban integrated pest management adviser for the Bay Area, recommends a simple preventive measure: reach for the hose.
Right after the bugs have hatched, “use pressure washers to push the larvae off the trees before they start wandering around,” he said. “In the late summer and fall, if you've got egg masses, you can wash them off and you won't have an issue next year on that tree.”
Bay Area pest control and horticulture experts say most caterpillar calls come from Santa Clara and southern San Mateo counties, which Sutherland linked to warm weather and high densities of host plants — the caterpillars are particularly fond of oak and fruit trees. Sutherland said he doesn't field nearly as many calls from the East Bay.
Hopland Research Center holds BioBlitz for Mendocino County students
(Ukiah Daily Journal) Curtis Driscoll, April 26
The Hopland Research and Extension Center held its annual “BioBlitz” on Friday for over 200 students from across Mendocino County, giving them a chance to explore their interest in science by finding new species at the Hopland Research Site.
The BioBlitz went on at the same time as the 2019 City Nature Challenge, an international event where people find and document plants and wildlife in cities across the globe. Although students in Mendocino County couldn't participate in the national event, the Hopland Research Center decided to have the BioBlitz as a way to allow students to explore nature in Mendocino County.
…Experts also helped the students learn more about the area in Mendocino County and the many kinds of unique species that are in the county. Anna Holmquist, an arachnologist from UC Berkeley, entomology students from UC Berkeley, and California Naturalists, people who have gone through a UC naturalist training program, were all available throughout the day to help students and guide them as they made different discoveries.
“We will be looking for species with them and searching and trying to add to the list, but there will be a bit more depth to it with the kids actually trying to build on their understand of our Mendocino habitats,” said Hopland Research Center Community Educator Hannah Bird.
Have the Tough Conversations: Koopmann Family Ranch Transfer
(Capital Press) Ashley Rood, April 26
… The next generation of Koopmanns, Carissa and Clayton, are well-poised to continue the family legacy of conservation and ranching. Both are building up their own cow herds on leased land while, as partners in the family LCC, they help make the big decisions. They also have full-time agriculture jobs off the ranch focused on grazing. Clayton is the range manager for the local water utility, the SFPUC, and has a grazing management consulting business. Carissa is a livestock and natural resources advisor for University of California Cooperative Extension in Siskiyou County. Both Carissa and Clayton emphasize how hard it is to make a living ranching alone, even with all the advantages of the family ranch. But getting out on the land, despite the hard work, is a place of relaxation for both of them.
For others considering succession planning, Carissa says, “Get started early and don't ever make assumptions. It's vital to know what everybody truly wants. Ultimately, the end goal that is that you're still a family, regardless of what happens.”

…In the words of Laci Gerhart-Barley, iNaturalist is "Instagram for biology and nature enthusiasts." The professor with the biological services department at the University of California, Davis, is even incorporating it into her classroom.
… Each year iNaturalist users participate in a "competition" to see what region can upload the most photos in the matter of a few days. The City Nature Challenge started as a competition between the California Academy of Sciences in San Francisco and the Los Angeles County Natural History Museum and gradually grew to include regions all over the world.
The Sacramento region is getting on board for the first time in 2019. [Sarah Angulo, community education specialist for the California Naturalist Program, is helping organize the challenge.]
The City Nature Challenge Sacramento will take place from Friday, April 26 to Monday, April 29.

UC: Older vineyards can be modified for mechanization
(Ag Alert) April 24
Saying they have proven that older vineyards can be converted to mechanization, University of California Cooperative Extension specialists say winegrape growers in the San Joaquin Valley do not have to replant vineyards if they want to switch to mechanical pruning.
Growers who want to make the switch can retrain the vines to make the transition, without losing fruit yield or quality, according to a UCCE study.
UCCE specialist Kaan Kurtural said the study found that "growers do not have to plant a new vineyard to mechanize their operations."
"We have proven beyond a doubt that an older vineyard can be converted to mechanization," he said.
There is no loss in yield during conversion, Kurtural said, "and post-conversion yield is better and fruit quality is equivalent to or better than hand-managed vines."
No replanting needed for mechanical pruning
(Farm Press) Tim Hearden, April 24
University of California (UC) researcher Kaan Kurtural has gained recognition in recent years for automating a vineyard operation in the Napa Valley, which was planted at a density conducive to the practice.
Now Kurtural and other UC Cooperative Extension scientists are applying their knowledge in the San Joaquin Valley, where they say growers who wish to switch from hand to mechanical pruning to save labor won't have to replant to do so.
Wet winter in Sonoma County may have helped spread virulent oak disease
(Press Democrat) Derek Moore, April 24
Now that the North Coast is finally drying out from an unusually wet winter, concern is growing over the potential rapid spread of sudden oak disease, renewing calls for the public's help tracking the deadly forest pathogen.
“Now is when we might expect the pathogen to take off a bit,” said Kerry Wininger, a UC Cooperative Extension staffer in Santa Rosa.
Wininger is a local organizer of annual sudden oak death surveys known as the SOD Blitz. This year's survey occurs from April 25 to 28 across Sonoma and Mendocino counties. Organizers are hoping for a good turnout of volunteers, who will become educated spotters and collectors to help scientists slow the disease's spread.
Young chefs: Local students prepare and taste international meals at fourth annual Culinary Academy
(Lompoc Record) Lorenzo J. Reyna, April 24
Twenty-one elementary school students spent part of their spring break learning to cook various international recipes inside Rice Elementary School's cafeteria Wednesday.
The fifth- and sixth-graders from 4-H Student Nutrition Advisory Council Clubs took part in the fourth annual Culinary Academy, spearheaded by six adults from UC CalFresh Healthy Living.
…Janelle Hansen helps oversee the 4-H SNAC Clubs as supervisor of the Santa Barbara and San Luis Obispo group.
She said Wednesday's five-hour event from 1 to 6 p.m. was much more than just students learning how to create various dishes.
“The hope is that they will learn the life skill of healthy living and nutrition — and that's really one of our goals,” Hansen said as the students were preparing their meals.

Mechanical Vineyard Pruning Possible Without Replanting
(AgNet West) Brian German, April 23
One of the major concerns regarding mechanical vineyard pruning is the time and cost associated with replanting a vineyard in a manner that would accommodate the process. However, a report from University of California Cooperative Extension researchers that was published in HortTechnology demonstrates that replanting is not necessary. Research conducted in Madera County found that growers can mechanize their operations by retraining vines without suffering any fruit loss or decline in quality.
“The trial actually ran for three years,” said Kaan Kurtural, UC Cooperative Extension specialist in the UC Davis Department of Viticulture and Enology. “In the end, there was like no loss in yield even during the conversion years and the quality was actually much better in the mechanically managed plants.”

California's high-value crops, like fruits and nuts, are the ones most vulnerable to climate change
(Fast Company) Larry Buhl, April 22
Agronomy, a peer-reviewed, open access scientific journal, laid out a stark future for California agriculture, predicting it will be vastly different by the end of the century. Led by Tapan Pathak of the University of California, Merced, the research team concluded that almost all of California's crops, together valued at more than $50 billion a year, will be endangered by rising temperatures and unstable weather patterns brought by climate change. The state will face wildly fluctuating precipitation patterns, leading to severe droughts and flooding, warming temperatures, more heat waves, and shorter chill seasons. The researchers wrote that the increased rate and scale of climate change “is beyond the realm of experience for the agricultural community,” and that changes in the state's crop output “would not only translate into national food security issues, but also economic impacts that could disrupt state and national commodity systems.”
