Pandemic And Wildfire: California Is Preparing For A Crisis Within A Crisis
(CapRadio) Ezra David Romero, April 15
…To protect human health, prescribed burns are not allowed for the time being on Forest Service land. But Ryan Tompkins, a forest advisor with the UC Cooperative Extension for Plumas, Sierra, and Lassen counties, says it's still early enough to prepare for wildfire with other tools like thinning and in some cases burning.
“It is really difficult because of the concerns about smoke and COVID, but sort of now is our chance to be prepared,” said Tompkins.
…“We know the agencies are going to have maybe limited capacity, limited resources, they're going to have other strains on their organizations while dealing with this crisis,” Tompkins said. “So, I think it emphasizes in a silver lining way that we all have a piece to play or a role to play.”
Susie Kocher, a forest adviser for the Lake Tahoe region with the UC Cooperative Extension, is concerned about a triple threat of COVID-19, wildfires, and power shutoffs.
“These two potential situations just could stack on top of the uncertainty of what people need to do,” she said.
Pandemic Crisis Got You Planting a Garden? Join the Club. (18:23)
(BYU Radio) April 14
Guest: Rose Hayden-Smith, PhD, Kellogg Food and Society Policy Fellow, Emeritus Professor of Agriculture and Natural Resources for the University of California, Author of "Sowing the Seeds of Victory: American Gardening Programs of WWI"
The pandemic has sparked a moment of “crisis gardening” among Americans. It's not much different from the Victory Gardens that sprung up in yards around the country during World War I, and then again in World War II.
New fungicide approved for Calif. tree nuts
(Farm Press) Tim Hearden, April 14
… University of California, Riverside plant pathologist Jim Adaskaveg helped develop data to validate the efficacy of ManKocide for California tree nuts and says the product has advantages, including ease of use.
It is also highly effective against copper-resistant bacteria in California, Adaskaveg said in an email.
“The product has efficacy against the walnut blight and bacterial spot of almond pathogens and suppresses fire blight on pome fruit and bacterial blast on almond,” he said.
Adaskaveg said he is unaware of other products that have this combination as a premixture,
People are rushing to plant 'pandemic gardens' and seed companies say they can't keep up with the surge in demand
(Business Insider) Michelle Mark, April 14, 2020
…It's not the first time economic crises have led Americans to grow their own food. One food historian told HuffPost that the trend began during WWI and WWII.
"Crisis-gardening is not new," Rose Hayden-Smith, the author of "Sowing the Seeds of Victory," told the outlet.
4-H searches for locals to serve on sponsoring committee
(San Benito Link) Devii Rao, April 14
We are looking for a few local people to serve on a sponsoring committee to keep 4-H active and strong in San Benito County. The sponsoring committee will organize events such as letter writing campaigns, barn dances, dinners, silent and live auctions, fireworks booths, having 4-H youth sell treats at the fair, or your other creative ideas! Sponsoring committee members are not required to have any affiliation with 4-H. We are looking for business leaders and other people who are well connected in the community and who are motivated to provide educational and leadership opportunities to our youth.
California dairies dump milk, crops may be left to wither as coronavirus pandemic disrupts food system
(SF Chronicle) Kurtis Alexander, April 12
…“Everybody's scrambling. The whole food system is scrambling,” said Daniel Sumner, an agricultural economist at UC Davis. “I don't see a big supply-side issue for agriculture. It's really an issue with the food (delivery) system.”
Widespread shutdown order slams California dairy farmers, ‘You can't turn off the cows'
(Sacramento Bee) Michael Finch II, April 10
…“Like every part of the food system, there are complications. The issue for milk is you can't turn off the cows,” said Daniel A. Sumner, an agricultural economist and professor at UC Davis. “What's becoming more of a problem is the slightly longer-term outlook where we have a massive recession (coming).”
Dairy prices are regulated by the federal government and fluctuate on the Chicago Mercantile Exchange. So the price of large quantities of milk, cheese, whey and milk powder is set based on data from the prior month, Sumner said.
In January, milk traded at nearly 18 cents per pound and by March the amount fell nearly five cents. Sumner said this suggests there is a price shock to come in the summer.
Grocers Serving Low-Income Neighborhoods Pinched by Shortages, Rising Prices
(KQED) Farida Jhabvala Romero, April 10
…“This hoarding behavior is unfortunate,” said Richard Sexton, a professor of agriculture and resource economics at UC Davis. “We can understand why people do it, but it is what's causing these disruptions.”
… The current shortages could deepen disadvantages for family-owned neighborhood stores, said Sexton, the UC Davis economist.
“The little guys, the small chains of just a few stores, could get the short end of the stick in this situation because food manufacturers and distributors are going to probably prioritize their biggest and best customers,” he said.
Private Grant Will Support New UC California Organic Institute
(Organic Farmer) Marni Katz, April 10
A $1 million endowment will establish the University of California's first institute for organic research and education within the UC's Agriculture and Natural Resources division (UC ANR), expanding the UC Cooperative Extension's research and outreach capacity to target organic growers in California.
UCANR points to help for Californians amid crisis
(Farm Press) Mark Bell, April 10
…In response to these pressing needs, UC Agriculture and Natural Resources, like many other universities and extension organizations across the country, are moving quickly to get more information online. While I haven't seen the actual numbers, we know millions of students (both high school and university) are quickly transitioning to online classes.
Scientists Worry Agency Plan to Prevent Fires Could Do Opposite
(Bloomberg) Bobby Magill, April 9
…Controlling wildfire in the region depends on how many firefighters the federal government has on the ground—and they'd have to be in the right place at the right time for the fuels reduction plan to work, said Max Moritz, a wildfire specialist at the University of California, Santa Barbara studying how wildfire affects broad landscapes.
As the climate changes, the effectiveness of fuels reductions projects and fuel breaks begins to fade, he said.
“Climate change seems to be priming the landscape for fires to ignite more easily, spread more easily, to burn hotter and larger—so all of these aspects of climate change would make one suspect that fuel breaks have a harder and harder time doing their job,” Moritz said.
The wildfire program is an “expensive large-scale experiment,” he said.
The real reason we're seeing more wildlife during the pandemic
(Pop Sci) Ula Chrobak, April 9
…In those cases, additional sightings might be due to simple behavior changes. But a less charismatic creature may be also on the rise due to an increased human presence at home. Niamh Quinn, a human-wildlife interactions advisor with the University of California, thinks that rat populations may be increasing in New Orleans and elsewhere. That's because people are cooking, storing, and disposing of at home, drawing rats away from closed restaurants and toward residences.
…Quinn agrees. Late last year, she radio-collared five coyotes in Los Angeles for a research project. She says that her coyotes haven't changed their routines since the shelter-in-place order went into effect, staying in their respective territories, which include areas near a shopping mall and golf course. Quinn adds that while the number of coyotes reported in San Francisco on the Coyote Cacher website isn't unusual, they could be moving about during the day more. “People are just at home noticing more things,” she says. “Especially in California, we're not all spending five hours a day on the freeway [now], you know?”
HLB spreads slowly, confined to residential citrus
(Capital Press) Padma Naggapan, April 9
…”It's slower than we expected, compared to Texas and Florida,” said Elizabeth Grafton-Cardwell. “In the Central Valley, homeowners and growers have been able to eradicate the pest, although it's been much more challenging in Southern California. But growers are doing an outstanding job of controlling the psyllids.”
Almond Update: Maximizing Yields and Sustainability from Start to Finish
(AgNet West) Taylor Hillman, April 9, 2020
Setting an orchard up for maximum yield and sustainability is a long game for producers. There are lots of variables, and some are unpredictable such as mother nature. But UC Cooperative Extension Tree Crop Advisor Franz Niederholzer said growers can do several things in the life of an orchard to stay in the game. He believes the most sustainable plan in every aspect of growing is to not focus on hitting home runs but instead have constant attention on management to help them avoid making outs.
Soil health practices show benefits
(Morning Ag Clips) Jeannette Warnert, April 9, 2020
A group of California organic farmers is sharing information about their efforts to combine reduced tillage with the use of cover crops, which they have been planting on their vegetable farms for decades to protect soil while adding carbon and diversity to their production systems.
“Every one of the pioneering farmers has seen tremendous benefits from the practices,” said Jeff Mitchell, UC Cooperative Extension vegetable crops specialist. “These are the very growing practices that we have demonstrated over two decades of research to benefit soil health, environmental conservation and the bottom line on plots near Five Points in Fresno County.”
Why are eggs getting so expensive? Blame coronavirus demand
(LA Times) Samantha Masunaga, April 8
…“Eggs are naturally, very often, one of the most price variable products in the supermarket,” said Daniel Sumner, UC Davis professor of agricultural economics and director of the UC Agricultural Issues Center.
…Egg prices could remain elevated for at least a few months, Sumner said. And the demand for eggs has been historically strong during tougher economic stretches. Eggs are a relatively cheap source of protein and aren't seen as a luxury food item.
“It may take longer to get back to normal for the egg business,” he said. “We can build supply, but it takes a few months.”
Rock Front Ranch permanently conserved for wildlife, grazing by Rangeland Trust
(Santa Maria Times) April 7
“To have this ranch be up against and abut to tens of thousands of acres of public lands is an indispensable connection to have in perpetuity,” said Matthew Shapero, livestock and range adviser in Santa Barbara and Ventura Counties for the University of California Cooperative Extension.
Nutrition experts fear 'dirty dozen' produce list will put off consumers
(UPI) Jessie Higgins, April 7
…"Our typical exposure to pesticides is far lower than levels of health concern," Carl Winter, an emeritus cooperative extension specialist in food and science technology at the University of California-Davis, said in an email.
"A graduate student and I published a paper in 2011 relating dietary exposure to toxicity for the 10 most frequently detected pesticides found on the EWG's 2010 Dirty Dozen list," he said. "Estimated exposures were far below levels of toxicological concern. Recommending consumers reduce their consumption of conventional fruits and vegetables on the Dirty Dozen list is unwarranted."
How to grow a vegetable garden, according to legendary chef Alice Waters
(Fast Company) Aimee Rawlins, April 7
… It's natural to want to go big and plant everything. But it's important to be realistic and start small, and not just because the productivity trap can be debilitating at a time like this.
“Right now we have enough on our plate. Start modestly and in a way that you can manage it,” says Missy Gable, director of the University of California's Master Gardener Program. “If you've never done this before, don't transform a quarter acre.”
… Because soil quality and composition varies depending on region and location, Gable recommends looking up your local master gardener extension program. These programs, which exist in all 50 states, offer classes and resources for home gardeners as well as knowledgable volunteers who are plugged in to local climate and soil particulars. Right now, some master gardener programs, like the one at Oregon State University, are also offering virtual classes. (OSU waived its fee for April and already has more than 17,000 participants.)

UC urges cattle producers to take precautions
(Farm Press) Larry Forero, Sheila Barry, Josh Davy, Gabrielle Maier, April 6
The COVID-19 pandemic has much of the California population staying home in an effort to reduce the spread of the virus. Across the state, many grocery stores have had shelves emptied of food and other day-to-day necessities as people have stockpiled these essentials.
Coronavirus hit California's cut-flower industry at the worst time
((LA Times) Geoffrey Mohan, April 4
…Cut flowers are a $1.3-billion industry nationwide, though most of that revenue comes from the sale of imported flowers, predominantly from Colombia, according to the UC Davis Agricultural Issues Center. Domestic growers account for about 27% of national sales, down from 37% roughly a decade ago. California-grown flowers account for three-quarters of the national domestic sales, according to the UC Davis researchers.
How The Coronavirus Pandemic Has Led To A Boom In Crisis Gardening
(Huff Post) Jodi Helmer, April 3
… Even though food supplies may be currently secure, said Rose Hayden-Smith, a food historian and author of “Sowing the Seeds of Victory,” understocked supermarket shelves are forcing shoppers to think about the source of their food, especially fruits and vegetables, often for the first time. And their fears have led them straight to the garden center.
“It's helpful to be productive and connect with nature and it's something that's within our control in a situation that feels entirely out of control,” she said.
Gardening during a pandemic
(Appeal Democrat) Chris Kaufman, April 3
Since the toilet paper panic-buying subsided, another item quietly flew off the shelves: garden seeds.
Springtime weather combined with shelter-in-place orders and empty shelves at stores has spurred a spike in seed sales, according to some gardening experts.
“I've seen an increase in seed sales because I've been looking around to see what people are doing and anticipating what kind of questions we will get once we open up again,” said Jan Kendel, a master gardener with the Sutter-Yuba University of California Cooperative Extension. “We've had some calls and emails from people wanting to know if it's a good time to plant tomatoes.”
Spotted Lanternfly is an Invasive Pest
(AgInfo) Tim Hammerich, April 2
The spotted lanternfly is a colorful insect pest that has been infesting vineyards and orchards in the eastern U.S. So far, we have been effective in our efforts to keep the pest away from California's multi-billion-dollar ag industry. But we must remain diligent in these efforts, says Dr. Surendra Dara, Entomology and Biologicals Advisor in San Luis Obispo and Santa Barbara Counties.
“Spotted lanternfly is an invasive pest because of the reason we don't have any natural enemies that can suppress their populations in a natural way in a new environment," said Dara. "And it can actually infest grapes and several other hosts in California of commercial importance. So it is important for us to be aware of the potential impact and do the need to prevent the damage."
The Moment for Food Sovereignty is Now
(Civil Eats) Katie Brimm, April 2
… “People are thinking, ‘If I can't get toilet paper, am I going to be able to get food?'” said Rose Hayden-Smith, a longtime community gardener and a Victory Garden historian, who recently retired from the University of California.
… Hayden-Smith notes that, despite the fact that the coronavirus pandemic came on much more suddenly than either World War, individuals and communities are once again turning to gardening to create food security.
California's truffle industry could be poised for growth if top hunter helps find path
(Sac Bee) Becky Grunewald, April 1
… Her dining companion is a tall scientist with a gentle demeanor, Scott Oneto. Although he didn't command the attention of this room, his work could be key to whether truffle cultivation becomes big business in local farming, or just a flash in the (frying) pan.
Oneto, a sixth generation California farmer with a background in weed science, had to be coaxed into the project, according to O'Toole. Oneto said after a few years of requests, it took a much-needed sabbatical, at which he could “really dive into research” to catch him at the perfect point to start their (hopefully) fruitful collaboration.
An Aggie through-and-through, Oneto got both his bachelor's and master's degrees at UC Davis, and works for Agriculture and Natural Resources. ANR is an unsung arm of the University of California, with the mission to bring the latest in agricultural science to the California community. Oneto not only bridges the gap to farmers by translating academic science research into in-person workshops and handouts, he also tailors research to local needs.
“When I have a farmer or rancher who is presented with problems, whether it be a new pest, weed, pathogen, or the effects of climate change, we help them solve those problems so they can continue to be successful in agriculture,” Oneto said.
Humboldt Using Satellite Tech Against Illicit Cannabis
(TechWire) Carl Smith, April 1
…“Local zoning, permitting and enforcement is probably more important than state-level initiatives, although collaboration across units of government is also key,” said Van Butsic, co-director of the Cannabis Research Center at the University of California, Berkeley.
In fact, every available strategy is needed as California works to implement the “robust standards” that it envisions for cannabis cultivation. For one thing, growers who are willing to play by the rules still face competition from illicit operations. In 2019, sales of illegal cannabis products in California were expected to hit $8.7 billion, more than twice the total for legal sales.
“Larger producers have been able to navigate the system,” said Butsic. “Many smaller growers are going out of business or staying illegal.” Costs are also part of the equation. “The illegal market is competitive because legal marijuana is so expensive to produce under Prop. 64,” Dale Gieringer, director of Cal NORML, told The Los Angeles Times.
GMOs Are an Ally in a Changing Climate
(Wired) Emma Marris, April 1, 2020
In Davis, California, 190 miles from Terranova, I met up with Pamela Ronald, a plant geneticist at UC Davis who has worked to solve this problem. Climate change is making floods worse in parts of South Asia, and in 2006, Ronald helped create a kind of rice that can survive submersion in water. By 2017, some 6 million farmers in Bangladesh, Nepal, and India were growing this rice. We talked in her cozy office, where a painting hangs on the wall of a man under a deluge of rain struggling to plow a field.
College farms still functioning amid shutdowns
(Farm Press) Tim Hearden, April 1, 2020
…Most employees for the UC's Division of Agriculture and Natural Resources are working remotely during their normal business hours and visiting sites in person for essential duties such as feeding animals, officials said. All the UC Cooperative Extension's in-person seminars and workshops scheduled for April were cancelled.
At the research centers, UC leaders are considering which projects should continue and which ones could be postponed, said Mark Lagrimini, UCANR's vice provost of research and extension.
“With the research that can go forward, we're making sure that protection is provided for the workers and students,”Lagrimini said. “We do have staff out there working right now. We have over 500 projects going on. We're in the process of going through 500 projects and making sure they are all able to be conducted safely. It's a big job.
UC ANR scientists urge citrus farmers and backyard growers to be vigilant in face of new disease find
This month, a lime tree and a kumquat tree with HLB were identified in residential areas of the San Gabriel Valley. In March 2012, an infected multi-grafted citrus was found in a Hacienda Heights backyard.
“So far, the bacterium that causes HLB has been found infecting only three trees, which have all been destroyed,” said Beth Grafton-Cardwell, UC ANR Cooperative Extension citrus entomology specialist. “However, it is highly likely there are other infected trees in California. It will be critical for all Californians to assist with efforts to reduce psyllids and detect and remove infected trees to prevent this disease from devastating California citrus.”
HLB disease is spread from tree to tree by Asian citrus psyllid, an invasive insect first identified in California in 2008. ACP has become established in many Southern California communities and is seen occasionally in the state's San Joaquin Valley and Central Coast commercial citrus production areas. Locations where ACP are found are quarantined by CDFA. No untreated or unprocessed citrus fruit and no citrus trees may be moved from these areas. UC ANR maintains an online map that delineates the quarantined locations. The map also shows the area quarantined because of the recent HLB find.
Once a tree is infected with the bacterium that causes HLB, there is no cure. To prevent HLB infections, citrus owners in areas where Asian citrus psyllids are found may wish to treat their trees with insecticides.
“We believe about 60 percent of Californians have at least one citrus tree in their yard, so HLB could have a devastating effect on the California residential landscape,” Grafton-Cardwell said. “There are safe and effective ways to reduce the ACP population, which reduces the chances of losing a tree to HLB.”
Grafton-Cardwell developed a website for farmers and residents with detailed information on managing Asian citrus psyllid. In some urban areas, a natural enemy of ACP, Tamarixia radiata, has been released. In those areas, Grafton-Cardwell recommends the use of “soft” insecticides that will reduce the number of psyllids and allow the Tamarixia to control the rest.
To help California residents and commercial citrus growers deal with the ACP and HLB citrus threats, UC ANR, UC Davis and UC Riverside scientists are conducting research on a number of possible solutions.
For example, Abhaya Dandekar, professor in the Department of Plant Sciences at UC Davis, and his colleagues are studying gene fusion, which fuses two immunosuppressive genes that attack HLB in different ways to make the plant more effective at fighting the disease.
Mikeal Roose, a professor in the Department of Botany and Plant Sciences at UC Riverside, is working with researchers in Florida to sequence a rootstock that has some natural resistance to HLB and locate the gene or genes that cause HLB resistance.
Mark Hoddle, UC ANR Cooperative Extension biocontrol specialist at UC Riverside, has identified a second natural enemy of ACP from the Punjab, Pakistan. (The first one was Tamarixia radiata.) Populations of Diaphorencyrtus aligarhensis have also been released in urban areas and Hoddle is monitoring the insect's ability to attack ACP.
Because it is important to remove trees infected with HLB as soon as possible to reduce spread, UC scientists are also studying ways to identify trees with the disease before visual symptoms occur.
For example, Hailing Jin, professor in the Department of Plant Pathology at UC Riverside, has identified small RNAs that are induced by the bacterium that causes HLB and could be used for early diagnosis.
Carolyn Slupsky, professor in the Department of Food Science and Technology at UC Davis, has identified metabolites that change in concentration when citrus is infected with the bacterium that causes HLB. She is working with the Citrus Research Board (CRB), CDFA, Texas A&M, and USDA to validate her results and determine how quickly the disease may be detected once the tree has been exposed to the pathogen. She is also part of a USDA collaborative grant to study the vector that transmits the disease to help find ways to stop transmission.
Wenbo Ma, professor in the Department of Plant Pathology Microbiology at UC Riverside, has developed antibodies against proteins secreted by the HLB pathogen – revealing whether the plant is infected. These antibodies have been evaluated in California, Florida and Texas for HLB detection.
An initiative to manage endemic and invasive pests and diseases is part of UC Agriculture and Natural Resources Strategic Vision 2025.
