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.

Moth caterpillars are back for a rare second bite in the Bay Area

To control western tussock moth caterpillars, “use pressure washers to push the larvae off the trees before they start wandering around,” Andrew Sutherland said.

(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.”

UC Extension head updates supervisors on programs and leaders

(Plumas News) Victoria Metcalf, April 24

The face of the Farm Advisor's office is changing.

Plumas and Sierra county Farm Advisor Director David Lile was before the Plumas County Board of Supervisors April 9, explaining just how much his staff has changed.

… Holding up a copy of the local University of California Agriculture and Natural Resources annual report for last year, Lile said, It's “easy to look at with plenty of pictures.”

…Lile then introduced Ryan Tompkins as the new forestry advisor. He replaces longtime representative Mike DeLasaux who retired in 2018.

…Natural resources and livestock liaison with local ranchers was introduced next. That's Tracy Scholr [Schohr].

…Most 4-H members and their parents already know 4-H Program Representative Kari O'Reilly.

… Tom Getts was also introduced as the technical assistance for Plumas and Sierra farmers and Susanville area land managers.

… And Barbara Goulet, as administrative assistant, provides support to the staff, but also works with local Master Gardener volunteers and 4-H volunteers, according to Lile.

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.

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.”

Making the case for fruits and vegetables

Why do you love fruits and vegetables? Is it their bright colors? Their many shapes and varieties, the way they can makeover your plate with the seasons? The opportunity to taste local terroir in a very fresh bite of fruit or forkful of salad?

Is it more about the juiciness, crunchiness or succulence?

Or do you think more about nutrition? About vitamins, micronutrients and fiber, after decades of being encouraged to eat “5 A Day” to be healthy? Is it about that feeling of righteous virtue when you fill half your plate with fruits and vegetables — and know you're earning a gold star for eating right?

The importance of eating fruits and vegetables has been making headlines again recently, with studies refocusing on the concept of “nutrition security” in a changing climate and pushing for an emphasis on nutrient consumption. The EAT-Lancet commission — while mostly garnering headlines in the United States related to reduced meat consumption — also recommended a diet that would require almost every global region to increase its consumption of fruits and vegetables to meet healthy diet goals.

But there's another reason to love fruits and vegetables that might not be as obvious. Here's a 30-second video clip of what a young farmer in Uganda had to tell me about vegetables, when I had the chance to meet him last year:

“There's no quicker source of getting money in town,” Boaz Otieno explained, when discussing why he chose to farm instead of going to town to find a job. He also talked about the concept that he could grow vegetables like tomatoes on a smaller plot of land and earn as much for those tomatoes as a larger plot of corn or cassava.

"You might even grow (tomatoes) twice while the cassava is not yet harvested, so there's a lot of money in horticulture," he said.

Otieno is a farmer who was also working as a site coordinator for a research project led by Kate Scow in Uganda, which was supported by the Horticulture Innovation Lab, the USAID-funded research program that I work for at UC Davis. Elizabeth Mitcham, director of the Horticulture Innovation Lab and a UC Cooperative Extension specialist, often talks about the “double-duty impacts” of fruits and vegetables, as these crops can be a tool to achieve two major global goals: improving nutrition and reducing poverty.

And it's not just one farmer's opinion that horticultural crops can yield higher incomes. In a white paper about aligning the food system to meet fruit and vegetable dietary needs, the authors pointed out that data from Africa and Asia have shown farmer profits per hectare 3-14 times higher when growing vegetables versus growing rice. The paper also points out that USDA estimates fruits and vegetables account for 23 percent of production value in American agriculture, grown on less than 3 percent of the country's agricultural land. And here in California, fruits and vegetables are a $20 billion industry.

Later this month, the Horticulture Innovation Lab will be hosting a conference in Washington, D.C., focused on making the case for fruits and vegetables with the theme, “Colorful Harvest: From Feeding to Nourishing a Growing World.” The conference will bring together decision makers, international development practitioners, and researchers from universities across the United States, Africa, Asia and Central America to discuss how horticultural innovations can advance global issues of food security, food waste, gender empowerment, youth employment, malnutrition, and poverty reduction.

While the conference speakers and participants will be diverse, we're also working to bring farmers' voices — like Otieno's — into the conference with video clips from our partners in Nepal, Honduras, Rwanda and elsewhere, to explain what exactly it is that makes them love fruits and vegetables.

Fighting drought with soil

Soil is an often overlooked tool to fight drought.
A team of University of California scientists recently received a $1.69 million grant to use several UC agricultural research stations to study an often overlooked tool to fight the drought: soil.

The team, led by Samantha Ying, an assistant professor of environmental sciences at UC Riverside, received the grant from the University of California Office of the President.

The funding will allow for the establishment of the University of California Consortium for Drought and Carbon Management (UC DroCaM), which will design management strategies based on understanding soil carbon, the soil microbiome and their impact on water dynamics in soil.

The researchers will conduct field and lab research on microbiological, biophysical, and geochemical mechanisms controlling soil formation and stability under different row crops (tomatoes, alfalfa, wheat), farming practices (carbon inputs and rotations) and irrigation methods (furrow and flood, microirrigation).

Samantha Ying, an assistant professor of environmental sciences at UC Riverside.
Information on mechanisms will be integrated into a regionally-scalable predictive model to describe soil carbon dynamics and estimate the response of agricultural systems to drought.

Field research will initially be conducted at three UC Research and Extension Centers (Kearney, West Side and Desert) the Russell Ranch Sustainable Agriculture Facility near UC Davis.

Recommendations will then be made for broader monitoring and field experiments throughout the state based on input gained from local growers and citizens at workshops at the agricultural research stations. Ultimately, the hope is to expand and involve all nine research and extension centers from the Oregon border to the Mexican border.

“Having agricultural research stations throughout the state is a huge part of this project,” Ying said. “It is going to help us create one of the best research centers in the country focused on soil and drought.”

There is also a public engagement component. Citizens will be recruited to participate in workshops to learn how to monitor and sample their local soils. Information will then be imputed into an online soils database that will help create a map of the biodiversity of agricultural soils in California.

Ying's collaborators are: Kate Scow and Sanjai Parihk (UC Davis); Eoin Brodie and Margaret Torn (UC Berkeley); Asmeret Berhe and Teamrat Ghezzehei (UC Merced); and Peter Nico and William Riley (Lawrence Berkeley National Laboratory).

The grant is one of four awards totaling more than $4.8 million from University of California President Janet Napolitano's President's Research Catalyst Awards.

UC studies soil to understand drought

Samantha Ying
A University of California, Riverside assistant professor and a team of researchers are using an often overlooked tool to fight the drought: soil.

Samantha Ying, an assistant professor of environmental sciences, will receive a $1.69 million grant from the University of California Office of the President that will allow her and her team to study the role of soil as it relates to how crops use water and respond to drought.

The grant is one of four awards totaling more than $4.8 million from University of California President Janet Napolitano's President's Research Catalyst Awards. The four winning projects were chosen from a pool of more than 180 proposals.

Ying will collaborate with researchers at UC Berkeley, UC Davis,UC Merced, Lawrence Berkeley National Lab and UC ANR research and extension centers.

California agriculture faces enormous challenges as climate changes and access to water is reduced and less predictable. California's recent drought is expected to cost the state over $2.7 billion with a loss of greater than 17,100 jobs in 2015 alone.

Soil, particularly soil carbon and its microbiome, plays a critical role in crop water use efficiency and crop response to drought. Physical, chemical and biological interactions in soil at the micrometer scale form soil aggregates that are critical in storing carbon and contain the small pores needed to retain moisture.

The grant will allow for the establishment of the University of California Consortium for Drought and Carbon Management (UC DroCaM), which will design management strategies based on understanding soil carbon, the soil microbiome and their impact on water dynamics in soil.

The team of researchers will conduct field and lab research on microbiological, biophysical, and geochemical mechanisms controlling soil aggregate formation and stability under different row crops (tomatoes, alfalfa, wheat), farming practices (carbon inputs and rotations) and irrigation methods (furrow and flood, microirrigation).

Desert Research and Extension Center is one of the field research sites.
Information on mechanisms will be integrated into a regionally-scalable predictive model to describe soil carbon dynamics and estimate the response of agricultural systems to drought.

The field research will be conducted at Kearney Agricultural Research and Extension Center, West Side Research and Extension Center and Desert Research and Extension Center and the Russell Ranch Sustainable Agriculture Facility near UC Davis.

Ying's collaborators are: Kate Scow and Sanjai Parihk (UC Davis); Eoin Brodie and Margaret Torn (UC Berkeley); Asmeret Berhe and Teamrat Ghezzehei (UC Merced); and Peter Nico and William Riley (Lawrence Berkeley National Laboratory).

Napolitano launched the President's Research Catalyst Awards in December 2014. The program channels $10 million over three years to fund research in areas of strategic importance, such as sustainability and climate, equity and social justice, health care and basic discovery.

To qualify, projects must be multi-campus, multi-disciplinary efforts that offer research, teaching and learning opportunities for undergraduate and graduate students. This year, applicants were also asked to incorporate public engagement and faculty mentorship components into the projects.

A day in the life of a 100-year agricultural experiment

Two women examine a soil sample in the background photo of the 'Soil Matters' field day flyer..
It's not every day that you can take a guided tour of a 100-year-long scientific experiment, but that's what is happening May 28 as UC Davis hosts a field day at the Russell Ranch Sustainable Agriculture Facility.

The 72-acre “Century Experiment” at Russell Ranch is exploring the long-term impacts of crop rotation, farming systems, and inputs of water, nitrogen, carbon, and other elements on agricultural sustainability. Researchers document trends affecting crop yields, soil quality, profitability, environmental impacts, and efficiency in use of limited resources.

“We look at both organic and conventional systems,” says Russell Ranch director Kate Scow, a professor in the Department of Land, Air and Water Resources at UC Davis. “We're continuing to learn how to better manage both systems in the long term, but it's also important to identify new farming systems that incorporate the best parts of both.”

The theme for the May 28 event is “Soil Matters: Underground at the Century Experiment.” Presentations will be made by faculty, farmers, graduate students, postdoctoral researchers, and visiting scholars. Topic areas include:

  • Nitrate leaching, drought and irrigation management in agriculture
  • Soil biology — microbial communities and impact on farming systems
  • Biochar — carbon sequestration and nutrient impacts
  • Soil nutrient budgets and management

The program gets underway at 8:00 a.m. with welcoming remarks, followed by a tour of research sites from the comfort of hay-bale wagons. Presentations move indoors to the barn at 10:30 a.m. A growers' panel discussion follows lunch. The program wraps up at 1:30 p.m.

Registration is $10 ($5 for students, free for farmers) and can be made online through May 26. Russell Ranch is located approximately six miles west of the main UC Davis campus.

Russell Ranch, part of the Agricultural Sustainability Institute in the College of Agricultural and Environmental Sciences, is a unique 1,500-acre facility with more than 300-acres dedicated to the study of dry-land agriculture in a Mediterranean climate. The crops grown there — tomatoes, corn and wheat — are the same crops grown in the region. Researchers have monitored changes in crop and soil properties, greenhouse gas emissions, weed ecology, and economic indicators there since 1993.

Among research highlights, scientists have shown that cover-cropped systems can be managed to store water in the soil, tomatoes grown with subsurface drip irrigation use less water and less nitrous oxide emissions, and the concentration of antioxidant compounds are higher in organic than conventional tomatoes.

“We may need to make some hard choices about water and nutrient inputs that could change the face of what we currently know as California agriculture,” Scow says. “So we need resilient systems that can endure and be productive in a changing and unpredictable climate.”

For additional information about the field day, contact Emma Torbert at eetorbert@ucdavis.edu or (530) 752-5208.
