Enormous wildfires spark scramble to improve fire models
(Nature) Jeff Tollefson, Aug. 31
…“Something is definitely different, and it raises questions about how much we really know,” says Max Moritz, a fire scientist at the University of California, Santa Barbara.
… The problem, Moritz says, is that most of the fire models in use today are based on data from the past two or three decades. But it seems that fire behaviour might be shifting in response to climate faster than anybody expected, and that makes it increasingly problematic to extrapolate from past trends, he adds.
Rodent control critical in subsurface alfalfa systems
(Farm Press) Todd Fitchette, Aug 31,
For alfalfa growers seeking other methods of rodent control, Dr. Roger Baldwin, Cooperative Extension specialist at UC Davis, says rodenticides, fumigants and trapping can be moderately to highly effective, depending on method and means used.
Deeply Talks: Fire & Drought–The Extremes Become Routine
(Water Deeply) Matt Weiser, Aug. 30,
The American West has entered an era of permanent water scarcity, a marked shift from previous periods of episodic drought. The same can now be said for fire: In California, there hasn't been a month without a wildfire since 2012. Join us for a conversation about the ways in which water and wildfire management intersect, and about the West's adaptation to its new, and far from normal, reality. We'll be joined by experts Crystal Kolden, associate professor of forest, range, and fire sciences in the College of Natural Resources at the University of Idaho, and Van Butsic, cooperative extension specialist at the University of California, Berkeley. Email our community editor with questions for the panelists (email@example.com) or tweet us @waterdeeply using the hashtag #DeeplyTalks.
Deadly poultry ailment, Newcastle disease, reaches Ventura County
(Ventura County Star), Aug. 29
Maurice Pitesky, a veterinarian and University of California extension specialist in the School of Veterinary Medicine at UC Davis, said one of the challenges in keeping a lid on the disease is the continued popularity of raising backyard chickens.
“While people have the best intentions, unfortunately a lack of biosecurity practices in people's backyards is one of the contributing factors of the disease spreading,” Pitesky said.
The longtime head of the UFW is stepping down. His replacement will be the first woman to lead the union
(LA Times) Geoffrey Mohan, Aug. 28
At its heart, the UFW remains torn between whether it can be both a grass-roots union and a broad social movement operating in the halls of power, said Philip Martin, a UC Davis agricultural economist and farm labor expert.
...“It is worth noting that the UFW does not have union locals, and so therefore does not have a system under which current farmworkers are trained in leadership development with the idea that they will rise within the union,” he said.
Expert Views: Managing Wildfires to Protect Water Resources
(Water Deeply) Lindsay Abrams, Aug. 28
Van Butsic, cooperative extension specialist at the University of California, Berkeley:
"Managing forest and wildfires to benefit water resources is difficult because there are trade-offs between short-term costs and long-term benefits. In the short term, wildfires can lead to increased erosion and sedimentation in streams and reservoirs. This contributes to lost revenue for downstream power generators and at times even requires water to be treated before it is potable."
Can Angelenos and Coyotes Coexist?
(LA Magazine) Henry Cherry, Aug. 27
…Intrigued by the animals, I stumbled across Coyote Cacher, an interactive website operated by University of California's Dr. Niamh Quinn. A native of Ireland, Quinn has been studying coyotes for about four years. “There are no coyotes in Ireland, but when I came here there was the need for coyote research in Southern California,” Quinn says. “There is a need for professional extension to the cities and the police departments, the people that never managed coyotes before but all of a sudden find themselves needing to do so.”
Why homes are lost to wildfire — is yours as safe as it could be?
(Mercury News) Lisa Krieger, Aug. 27
…“When you start to understand why homes burn, often through embers igniting fuel in home attics or adjacent to homes, then it is easier to understand these patterns,” said Kate Wilkin, a fire specialist for UC Cooperative Extension.
Limiting suburban sprawl can ease the devastation of wildfires
(Mother Nature Network) Matt Hickman, Aug. 27
…But there's a bigger issue at hand. Max Moritz, a wildfire specialist with the University of California's Division of Agriculture & Natural Resources, relays to Martin Kuz of the Christian Science Monitor that inaction from state lawmakers who are reluctant to lead the charge in restricting development in vulnerable areas is only worsening the situation. Presently, local officials, developers and homeowners face few limitations when building in fire-prone wild land urban interfaces. Moritz refers to this as a “political will problem.”

Idea to Reduce Glyphosate Use with Grapes
(Cal Ag Today) Mikenzi Meyers, Aug. 23
John Roncoroni, a UC Cooperative Extension Weed Science Farm Advisor in Napa County, has made strides toward meeting this challenge. “Many times, growers will do two applications of herbicides during the year … but what I'm trying to do is push it back to post-leaf fall after the season to clean up and come back with a pre-emergent material right before bud break then maybe skip that last glyphosate treatment after bud break.”
California Today: The Human Element in California's Wildfires

The Social Costs of Living in Wildfire-Prone Areas
(East Bay Express) Alastair Bland, Aug. 21
…"But that's so politically contentious — it's a line politicians walk up to but turn away from," said William Stewart, a UC Berkeley forestry and wildfire specialist.
… “People seem to have short memories," said Sabrina Drill, a natural resources advisor for the UC Cooperative Extension, a statewide off-campus division of the university system that focuses on agriculture and natural resources. "I think people might think twice about building a home where there had just been a fire, but people seem to forget after about three years."
… Van Butsic, a UC Berkeley researcher who studies forestry and land use, has closely studied this. In a paper now under review for publication, he and scientist Anu Kramer, from the University of Wisconsin, describe an alarming trend of building homes in known fire-risk areas.
"We studied 30 of the largest fires since 1970," he said. On average, they found that 20 years after an inhabited area burns, not only were most of the destroyed homes rebuilt but many new homes were added — about twice as many homes in total as there were at the time of the burn.
… In 2016, researcher Susan Kocher spent nine months on sabbatical in Provence, the arid region of southern France that resembles much of inland California. Here, Kocher — the Central Sierra Natural Resources Advisor for the UC Cooperative Extension — compared building patterns in high-fire risk parts of California and France.
"In California we often say, 'We should be able to tell people they can't build here,'" said Kocher, whose research, coauthored with Butsic, was published in March of 2017 in the journal Land. "In France, they just tell people they can't build somewhere."
Cooperative Extension adapts to a less agricultural America
(Washington Post) Dean Fosdick, Aug. 21
In its century of existence, the Cooperative Extension System has been a valuable resource distributing university-driven, science-based information — mostly about farming and gardening — to the public. But in today's less agricultural America, the Extension network is adapting, expanding its rural focus into cities and suburbs too.

Israel and UC deepen water technology collaboration
(Jewish News of Northern California) Hannah Jannol, Aug 17
S.F.-based Consul General of Israel Shlomi Kofman attended the MOU signing ceremony on July 16, held during a three-day workshop titled, “The Future of Water for Irrigation in California and Israel.” The document was signed by an agricultural division of the University of California, UC Davis and the Agricultural Research Organization of Israel.
… Doug Parker, director of the California Institute for Water Resources, helped put the MOU together. He said California and Israel already work together frequently on water research, but formalizing the relationship could give the two parties more leverage when applying for grants and funding.
‘Batnadoes' Can Protect California's Crops
(Atlas Obscura) Anne Ewbank, Aug. 16
… He's likely right, according to Rachael Long, a farm advisor with the UC Cooperative Extension in the Sacramento Valley. She's researched for decades how bats can help farmers control pests. “Armyworms are always a big problem in rice production,” she says. “Bats are predators, of armyworms, cutworms, and other pests.” Bats' nocturnal feasts prevent adult moths from laying eggs that will hatch into hungry, rice-eating caterpillars, and, Long says, their impact cannot be overstated. When pest populations get out of control, “it can be really devastating.”
Wildfires Are Inevitable – Increasing Home Losses, Fatalities and Costs Are Not
Wildfire has been an integral part of California ecosystems for centuries. Now, however, nearly a third of homes in the state are in wildland urban interface areas where houses intermingling with wildlands and fire is a natural phenomenon. Just as Californians must live with earthquake risk, they must live with wildfires.
USDA awards UC and Karuk Tribe $1.2 million for collaborative research and education to increase tribal ecosystem resilience in a changing climate
As California and the nation grapple with the implications of persistent drought, devastating wildfires and other harbingers of climate change, researchers at UC Berkeley's College of Natural Resources are building on a decade-long partnership with the Karuk Tribe and the U.S. Forest Service Pacific Southwest Research Station to learn more about stewarding native food plants in fluctuating environmental conditions. UC Berkeley and the Karuk Tribe have been awarded a $1.2 million USDA Agriculture and Food Research Initiative grant for field research, new digital data analysis tools and community skill-building aimed to increase resilience of the abundant cultural food and other plant resources – and the tribal people whose food security and health depend on them.
Jennifer Sowerwine, UC Cooperative Extension specialist at UC Berkeley and co-founder of the Karuk-UC Berkeley Collaborative, and Lisa Hillman, program manager of the Karuk Tribe's Píkyav Field Institute, will co-lead the xúus nu'éethti – we are caring for it research project.
UC Berkeley's College of Natural Resources, UC Agriculture and Natural Resources and the Karuk Department of Natural Resources will support the project with postdoctoral researchers, botany, mapping and GIS specialists, and tribal cultural practitioners and resource technicians. Frank Lake, research ecologist and tribal climate change liaison at the USFS Pacific Southwest Research Station, will contribute to research and local outreach activities. The San Rafael-based nonprofit Center for Digital Archaeology will help develop a new data modeling system.
Project activities include expanding the tribe's herbarium (a research archive of preserved cultural plants launched in 2016 with UC Berkeley support), developing digital tools to collect and store agroecological field data, and helping tribal community members and youth learn how to analyze the results.
“For the xúus nu'éethti – we are caring for it research project, UC ANR's Informatics and Geographic Information Systems (IGIS) team will lead hands-on workshops and consultations to build Karuk Tribal capacity to assess, monitor and make management decisions regarding the agroecosystem,” Sowerwine said. “Workshop curricula for tribal staff and community members will include GIS training, 360 photospheres and drone images, and storymapping techniques. IGIS will also provide technical analysis of historical land use and land cover records to support researchers' understanding of agroecological resilience over time.”
“We are delighted to continue our connection with UC Berkeley through this new project,” said Hillman. “Through our past collaboration on tribal food security, we strengthened a network of tribal folks knowledgeable in identifying, monitoring, harvesting, managing for and preparing the traditional foods that sustain us physically and culturally. With this new project, we aim to integrate variables such as climate change, plant pathogens and invasive species into our research and management equations, learning new skills and knowledge along the way and sharing those STEM skills with the next generation.”
The research team will assess the condition of cultural agroecosystems including foods and fibers to understand how land use, land management, and climate variables have affected ecosystem resilience. Through planning designed to maximize community input, they will develop new tools to inform land management choices at the federal, state, tribal and community levels.
All project activities will take place in the Karuk Tribe's Aboriginal Territory located in the mid-Klamath River Basin, but results from the project will be useful to other tribes and entities working toward sustainable management of cultural natural resources in an era of increasing climate variability. Findings will be shared nationwide through cooperative extension outreach services and publications.
The new project's name, xúus nu'éethti – we are caring for it, reflects the Karuk Tribe's continuing commitment to restore and enhance the co-inhabitants of its aboriginal territory whom they know to be their relations – plants, animals, fish, water, rocks and land. At the core of Karuk identity is the principle of reciprocity: one must first care for these relations in order to receive their gifts for future generations.
This work will be supported by the Agriculture and Food Research Initiative Resilient Agroecosystems in a Changing Climate Challenge Area, grant no. 2018-68002-27916 from the USDA National Institute of Food and Agriculture.

Abnormal Weather Takes a Toll on California Olive Crop
(Ag Net West) Brian German, May 30
The late winter freeze caused significant issues for several different commodities throughout the state and has been especially problematic for the California olive crop. The fluctuating temperatures have created substantial concern among the industry as bloom looks to be far below normal levels.
“Overall we're a little on the pessimistic side. The bloom, on the whole, has been pretty poor, many orchards actually have a very light, to next to no bloom at all,” said Dani Lightle, Cooperative Extension Orchard Systems Advisor for Glenn County. “There's an orchard here or there that looks pretty good, but on the whole, it is a little bit dismal.”
(LA Taco) Gab Chabran, May 29
…Eric Focht who is a staff research associate in the lab of Mary Lu Arpaia at UC Riverside through UC Agriculture and Natural Resources and the Department of Botany and Plant Sciences tells L.A. Taco that the recent avocado economy boom is “similar to what we see today with something like bitcoin.” He helps run a breeding program at UCR studying different avocados varieties, focusing mostly on Hass avocados but also looking at other less known versions of the popular fruit.
In short, he is working on breeding the perfect avocado that tastes great and is easier, faster, and less water-dependent to grow. This year is shaping out to be a good one for avocados, but this issue is always one to keep in mind.
Focht states that in the future, there will likely be more variety available in the mainstream marketplace. One varietal that Focht gets excited about is the Reed avocado which has now been popping up in places such as Whole Foods. It's known for its round, dinosaur egg shape and is about the size of a softball. It has a relatively large seed but the edible flesh is sometimes double or even triple that of a Haas that can make a lot more people happier per individual fruit.
(Chico News & Review) Ashiah Scharaga, May 24
When drifting clouds dapple the sky and vibrant wildflowers—tickled pink buds, honey-hued petals and virent stems—awaken in the verdant fields of Table Mountain, explorers quicken their pace. They spot trickling streams and grazing cattle. Occasionally, they look straight down, turning anxious eyes to their mud-slicked heels—did they step in one of the fertile cow-pie mines littered across the landscape?
That may seem a nuisance, but it's a necessity. Tracy Schohr, a livestock and natural resources adviser for University of California Cooperative Extension, said the natural magic of the popular Butte County recreational spot is made possible because of a long-standing grazing program. “If cattle were not actually on Table Mountain Ecological Reserve,” she said, “essentially those invasive species would choke out those native plants, and they wouldn't be there.”
… In the past, grazing was misunderstood and primarily viewed as destructive, said Dave Daley, a fifth-generation Butte County cattleman and associate dean of Chico State's College of Agriculture. He credits changing perspectives to the development of grazing science, fueled by people such as Schohr and Kate Wilkin, a UC Cooperative Extension forestry, fire science and natural resource adviser for Butte, Yuba, Sutter and Nevada counties. (Schohr covers Butte, Plumas and Sierra counties.)
Sheep Shearing 101: Why Aspiring Shavers Flock to This California School
(KQED) Tiffany Camhi, May 23
…“We try to get the students shearing the first day because they make a lot of mistakes,” says John Harper, head of the UC Cooperative Extension Sheep Shearing School in Hopland.
Harper says if you can make the right moves with your feet, everything else falls into place.
“We're dancing instructors,” says Harper. “It's like 'Dancing With The Stars' on steroids, but with sheep.”
Around this time of year, hundreds of thousands of sheep in California need to have their wool shaved off. But Harper says there's a shortage of sheep shearers worldwide.
That's why he started the school in Hopland about 25 years ago.
Dan Macon of the California Wool Growers Association says the growing popularity of backyard flocks in California (usually just a handful of sheep) is adding to the demand for shearers, too.
“Infrastructure of the sheep industry is a key component,” says Macon. “Having people with that kind of skill and willingness to work hard is desperately needed.”
AUDIO: Hey, Salad Lovers: It's OK To Eat Romaine Lettuce Again
(NPR Morning Edition) Allison Aubrey, May 23
…After a big foodborne illness outbreak linked to baby spinach back in 2006, the leafy greens industry put in place a number of procedures to prevent contamination. "Prevention became the major focus after that outbreak," says Michele Jay-Russell, a food safety researcher at the University of California, Davis.
"They set up intensive testing protocols to monitor water quality," Jay-Russell says. The industry also agreed on standardized setbacks — or buffers — to separate growing fields from livestock operations, which can be a source of E.coli contamination. "You want a safe distance from where you're growing fresh produce and where you have concentrations of animals, like on a feedlot or dairy," she says.
Are avocados toast?
(Grist) Nathanael Johnson, May 22
…When Katherine Jarvis-Shean was a doctoral candidate researching the decline of cold winters a few years back, she thought more farmers should be freaking out. “I used to think, ‘Why aren't you guys more worried about this? It's going to be the end of the world.'”
After all, many fruit and nut trees require a good winter chill to bear fruit. But after spending a few years as an extension agent for the University of California — working directly with farmers and translating science into techniques they can apply on the land — she understands better. It comes down to this: Farmers have a ton of concerns, and the climate is just one of them.
“If you decide what to plant based on climate, but then can't make the lease payment, that's not sustainable,” Jarvis-Shean said.
Lanternflies Eat Everything in Sight. The U.S. Is Looking Delicious.
(New York Times) Zach Montague, May 21
…Native to Asia, lanternflies first appeared in Pennsylvania in 2014. Despite a quarantine effort, they have also been discovered in small numbers in New York, Delaware and Virginia.
… “Most pests deposit their eggs on their host plant, or very close, so they already have food available,” said Surendra Dara, an adviser at the University of California Cooperative Extension.
“Those that have the advantage of being able to lay eggs on non-plant material obviously have a better chance of surviving and spreading,” he added.
Garbanzos are catching on in Yolo County
(Woodland Daily Democrat, Ag Alert) Bob Johnson, May 19
…“The largest part of our crop goes to canning, maybe 90 percent,” said Paul Gepts, UC Davis plant sciences professor and legume breeder. “California can only compete with high quality products. We have other varieties with higher yields, but the seeds are too small. The growers get a premium for larger, high quality seeds.”
Gepts developed the two newest UC garbanzo varieties, Vega and Pegasus. Both have large, attractive seeds well suited for the canning market, and both have resistance to Ascochyta blight, a fungal disease that can devastate the crop.
… “I think growers are more interested in garbanzos because it's a winter crop, and wheat prices are low,” said Rachael Long, UC Cooperative Extension farm adviser in Sacramento, Solano and Yolo counties. Long is finishing up UC's first Garbanzo Production Manual, which should be available before the end of the year.

Kale, Not Jail: Urban Farming Nonprofit Helps Ex-Cons Re-enter Society
(New York Times) Patricia Leigh Brown, May 17
Even by the standards of the Bay Area, where sourcing local, organic chicken feed is seen as something of a political act, the spectacle of 30,000 fruit and nut trees being tended by formerly incarcerated orchardists is novel.
…Jennifer Sowerwine, an urban agriculture specialist for the University of California Cooperative Extension at Berkeley, said that Ms. Haleh and Mr. Raders have “shifted the conversation around food justice.”
“It's not just about food security, but the security of providing living wages,” she said. That's no mean feat in a foodie monoculture.
Tough winter weather devastates local cherry, blueberry crops

Machines take over for people at Napa vineyard
(Capital Press) Tim Hearden, May 14
In the heart of the Napa Valley, a vineyard produces fine Cabernet Sauvignon with virtually no help from laborers.
The 40-acre “touchless vineyard” was established by Kaan Kurtural, a University of California Cooperative Extension specialist who has devoted much of his career to improving production efficiency in vineyards as labor shortages have worsened.
…When Kurtural started experimenting with vineyard automation 10 years ago, his primary goal was to save growers money in labor costs, he said. But since then, research has shown that grape quality is superior, largely because the tall canopy protects grapes from sun damage, he said. The system also uses less water than others, he said.
Dozens of strawberry growers gather in Santa Maria to learn latest industry advancements
(KSBY Staff) May 9
More than 100 farmers and growers took park in a meeting teaching them on the best way to grow a healthy strawberry.
The University of California put on the annual event which was free to the public.
Growers discussed improvements handling weeds, disease, and insects.
The Santa Maria Valley is the second largest strawberry growing area in California after the Salinas Valley.
The crop means a lot to people in Santa Maria.
"We've got a number of challenges to the California strawberry industry and we're doing are best to work together," said Steven Fennimore of University of California Cooperative Extension Agriculture and Natural Resources. "I'm optimistic that we'll find some satisfactory solutions."
Growers talked about all kinds of different ways to boost their crop including ways of using images from aircraft to detect stress in plants.
Pesticide Use on California Farms at Near-Record Levels
(Fair Warning) Paul Feldman, May 9
…Some experts say long-term changes in the mix of items farmers produce in California, including increases in almonds and other high value crops, give the agriculture industry the incentive to use more pesticides. Such crops present “a larger economic risk if pests are not controlled,”said Brad Hanson, a weed specialist at the University of California, Davis, plant science department.
Jim Farrar, director of the University of California's statewide integrated pest management program, added that more pesticides are needed when “you move from something like alfalfa and sorghum for dairies, where cosmetic injury isn't a problem … to something like oranges where if there's a blemish on the rind you get downgraded even if the orange is perfectly healthy.”
Cherry growers expect lighter crop yields
(Ag Alert) Ching Lee, May 9,
…Kari Arnold, a University of California Cooperative Extension farm advisor in Stanislaus County, said she's careful not to paint the 2018 cherry season as a disaster year "because it's really not." The crop may not be as robust, she said, but this was somewhat expected, because last year's crop was so big.
What wasn't expected, she said, was the freeze in the spring, which "did cause some damage to flowers." But the damage varied depending on the location of the orchard and whether growers were able to apply frost protection, she added.
"It's still going to be a good crop," she said. "It may not be the same as last year, but they're going to be good cherries. They're probably going to sell at a higher price because there'll be less of them."
She said she's concerned that word of it being a light crop may scare away field help, adding that "it's hard enough to get field labor in the first place anymore, because labor is becoming more and more difficult to come by and more difficult to keep."
Peak Avocado Is Yet to Come
(The Atlantic) Cynthia Graber, Nicola Twilley, May 9
…Its partners in evolution—the giant, elephant-like gomphotheres and three-ton ground sloths that dined on its fruit in return for transporting and then pooping out its giant seed—went extinct soon after the first bipedal apes arrived in the region. Rodents, jaguars, and eventually humans stepped in as dispersal mechanisms, albeit significantly less effective ones. The flourishing avocado forests that carpeted much of Mesoamerica dwindled and died out. And, as Mary Lu Arpaia, who runs the avocado breeding program at the University of California at Riverside, explained, the avocado became a backyard fruit, enjoyed by first the indigenous peoples and later the conquistadors, but rarely cultivated intensively—until recent decades.
Climate change ruining California's environment, report warns
(SF Chronicle) Peter Fimrite, May 8, 2018
“If I were going to look across North America, ground zero for climate change is the Arctic. It is just changing really, really rapidly,” said Steven Beissinger, professor of conservation biology at UC Berkeley. “But California is an important laboratory to understand the effects of climate change on biodiversity.”
More illnesses with later onset dates linked to romaine outbreak
(The Packer) Ashley Nickle, May 8, 2018
Richard Smith, a University of California Cooperative Extension advisor based in Salinas, also said the outbreak is hurting sales.
“It's having an effect,” Smith said May 7. “This is the problem — lettuce is pretty expensive to grow, and you've got to cover your costs. You can lose money, at this point the bigger growers can afford to lose for a period of time, but then they've got to make it up, and it just makes it hard. We're not sure how the year's going to go.
“I guess the good news is that the consumers are being sophisticated enough to be focusing on the romaine (versus all lettuce) ... The reality is I guess the FDA doesn't want to clear romaine yet because they think that the lettuce from Yuma might have a 21-day shelf life, so until the FDA clears it and then that news gets clearly articulated, I think it's going to be a damper.
AEI economists say farmers have ‘beef' with Trump
(Hagstrom Report) May 7, 2018
…Daniel Sumner of the University of California at Davis also told The Hagstrom Report that farmers hurt by the administration's trade policies have "a beef" with Trump.
Sumner said that even though the tariffs on Chinese steel and aluminum have not yet gone into effect, California farmers including wine and almond producers are already worried. "Even if the tariffs don't happen, the rhetoric has effects," he said.
Sumner also said that Mexican buyers of U.S. dairy products — "reasonable business people in Mexico" — began months ago to contact New Zealand dairy producers about becoming a supplier because the Mexicans are worried about the impact of the North American Free Trade Agreement renegotiation.

Egg prices plunge as supplies rebound
(Capital Press) Tim Hearden, May 4
Commercial egg prices in California are plummeting, and a slow global economy combined with a rebounding chicken flock after last year's devastating avian flu outbreak are among the contributing factors.
…At first, Midwestern egg producers that didn't want to retrofit their barns simply avoided California. Those that did want to market to California found confusion in what actually constituted a Proposition 2-compliant cage, said Joy Mench, a University of California-Davis animal science professor.
“(T)he wording of Prop. 2 does not allow it to be regulated, so there is no official definition of what it means,” Mench said in an email. “That will have to be decided in the courts, either because there is a lawsuit or because someone is prosecuted.”
In enforcing the initiative, the CDFA uses the federal Shell Egg Food Safety rule, whose space requirement is larger than the United Egg Producer guidelines that most of the other states use, noted Maurice Pitesky, a poultry specialist at the UC-Davis School of Veterinary Medicine.
Farming takes center stage at Yolo County Fairgrounds
Woodland Daily Democrat) Cutter Hicks, May 4
Field trips to the fairgrounds led to a farming experience for students as the Yolo County 4-H and Farm Bureau hosted its 10th annual Farm Connection Day to kick off the Spring Show this weekend.
The four-hour event Friday featured more than 100 agricultural displays and hands-on activities for kids of all ages as nearly 2,500 visitors walked through the gates.
Farm Connection Day was open to the public and more than 200 4-H students teamed up to host the event — with a little help from adult volunteers. Their focus was to teach students of Yolo County the aspects of the organization before judging shows later that day.
DeAnn Tenhunfeld, a Farm Connection Day organizer, said that the attendance was the largest seen since she founded it in 2008.
Frost damage varied for California nut trees

Some almond growers experienced frost damage from recent freezing conditions, say University of California experts.
“There's really a lot of damage,” says Katherine Jarvis-Shean, UC Cooperative Extension orchard systems advisor for Sacramento, Solano, and Yolo counties. “The earlier varieties really took a hit. Some trees even dropped their nuts due to frost damage. It's pretty bad in some orchards.”
… Bruce Lampinen, UCCE almond and walnut specialist, measured temperatures in an almond trial at Davis, and notes that “Feb. 20 and 24 were the coldest days. It was very problematic because that's when the trees were in full bloom.” At full bloom, temperatures below 28 degrees F. can cause crop loss.
…Phoebe Gordon, UCCE orchard systems advisor for Madera and Merced counties, says, “From what I've seen and heard, the damage has been variable. Some orchards weren't hit that hard, and others were hit very hard. I think it depended a lot on micro-climate and what stage the trees were in. They become more susceptible to frost damage as they transition from dormant to full bloom, and to nut set. I don't think we'll really know until ‘June drop' is finished what the final load is.”
Dani Lightle, UCCE orchard systems advisor in Glenn and Butte counties, says, “Almonds were right in the middle of full bloom when the frost happened. Most of the orchards in my area seem to have escaped. We didn't seem to cross the threshold to where there was heavy damage. Of course, there are exceptions, but by and large we came out better in the end than we thought we would.”
New weapon in fight against walnut blight
(Farm Press) Robyn Rominger, May 2, 2018
Walnut growers have a new tool to help manage blight disease in their orchards — Kasumin 2L, manufactured by Arysta LifeScience, is the trade name for kasugamycin, and is available as part of a strategy to control the disease.
The new bactericide was discussed at a recent University of California Cooperative Extension breakfast meeting at Yuba City. “It's great to have another chemistry in the rotational loop for blight management in walnuts,” says Emily Symmes, UCCE integrated pest management advisor.
The East Oakland non-profit organization Planting Justice hires former inmates, many from San Quentin, and pays them a family sustaining wage to work on urban farms, orchards and nurseries, and offer environmental education, reported Patti Brown in the New York Times.
Of the 35 formerly incarcerated workers hired by Planting Justice since 2009, only one is known to have returned to prison. Employees must commit to staying sober and drug free.
Jennifer Sowerwine, UC Cooperative Extension specialist at UC Berkeley, said that the organization's founders, Haleh Zandi and Gavin Raders, have “shifted the conversation around food justice.”
“It's not just about food security, but the security of providing living wages,” she said.
Sowerwine said she learned about Planting Justice a few years ago in an urban farming focus group and worked with the program on many projects. She suggested the New York Times reporter do a feature story on Planting Justice, set up the interview and attended the site visit to support the introduction.
Planting Justice, in partnership with the Multinational Exchange for Sustainable Agriculture, were recipients of a Beginning Farmer and Rancher Development Program Grant from USDA at the same time as Sowerwine.
"We collaborate and support each other's programs through providing mutual guidance, co-sponsoring events, and offering opportunities for shared learning for our participants," Sowerwine said. "We are exploring deeper partnerships with a MESA/PJ training program at the Gill Tract as well in an effort to raise the profile of urban farming, and amplify successful and innovative urban agriculture approaches."
