UC ANR NEWS
National Public Radio highlighted a growing concern for San Joaquin Valley tree fruit and nut farmers - diminishing winter chill in an age of climate change. "Warm winters mess with nut trees' sex lives," reported Lauren Summer on Morning Edition.
For example, adequate winter chill allows female and male pistachio trees to wake up simultaneously, which is ideal for pollen to be available for wind to carry it to blooms on female trees.
Fresno State agriculture professor Gurreet Brar, a former UC Cooperative Extension advisor, is testing whether horticultural spray application at different chill-hour intervals will trick trees into thinking they've been colder. Normally, the spray is used on fruit and nut trees to control insects, but it's also known to alter the tree's dormancy period.
"It's supposed to help the tree and buds wake up normally and have a normal bloom," Brar said.
Summer also spoke to Katherine Jarvis-Shean, UC Cooperative Extension orchard systems advisor in Yolo County.
"We're on this (climate change) march and it's really just a matter of how bad it's going to be, not whether it's happening or not," Jarvis-Shean said. "Threatening those crops is really threatening the livelihoods of a lot of Californians."
Fruit and nut trees that require the most winter chill will run into trouble by mid-century, when experts predict consistently warmer weather, Summer reported.
"Bing cherries, which is really the marquee variety in California, won't get enough chill," Jarvis-Shean said. "We'll need to be breeding new varieties that still have that rich ruby flesh and that juicy flavor that can do well under those low chill conditions."
Better-adapted trees may be the only strategy in the long-run, she said. Efforts are already underway to breed new varieties of pistachios that can handle warmer winters.
California ag faces a decade of challenges
(Farm Press) Tim Hearden, Jan. 31
…“We're getting close to a point where field work in agriculture is similar to or higher than the wages in other sectors,” said Dan Sumner, director of the University of California's Agricultural Issues Center in Davis. “But the problem is the hours of work.”
Much of agricultural work is seasonal, making the 40-hour work week impractical in many circumstances, Sumner and others say.
…When they mechanize, growers encounter more regulations. For instance, Steve Fennemore, a UC plant sciences specialist in Salinas, has been helping a company develop an autonomous weeder and is aghast at a state safety requirement that there be a person within 10 feet operating each agricultural robot in use.
“We have a tremendous labor shortage,” Fennemore said. “We have teams of robots working a field. Why do I need more than one person to run them?
“Shouldn't we be encouraging this kind of research” into labor-saving tools, he asks. “We need to do everything we can to mechanize.”
Pistachio Winter Juvenile Tree Dieback A Confounding Issue
(AgNet West) Brian German, Jan. 31
Pistachio growers will be watching for signs for winter juvenile tree dieback (WJTD) as trees begin to come out of dormancy in the spring. Damage is typically found in trees between three and five years old, although there have been instances where older trees in their seventh or eighth year have been affected. Narrowing down the exact cause of the issue also presents its own set of challenges
“I'm somewhat hesitant to call it freeze damage because we've seen it in places where we couldn't find a freeze. But I think more than anything it has to do with root hypoxia; that's a lack of oxygen in the root zone,” said Craig Kallsen, UC Farm Advisor in Kern County. “We see it in old lakebeds, low elevation areas where cold air collects but that's also where the salt is so it's hard to separate those factors.”

Young California ranchers are finding new ways to raise livestock and improve the land
(Conversation) Kate Munden-Dixon and Leslie Roche, Jan. 28
As California contends with drought, wildfires and other impacts of climate change, a small yet passionate group of residents are attempting to lessen these effects and reduce the state's carbon emissions. They are ranchers – but not the kind that most people picture when they hear that term.
These first-generation ranchers are young, often female and ethnically diverse. Rather than raising beef cattle destined for feedlots, many are managing small grazing animals like sheep and goats. And they are experimenting with grazing practices that can reduce fire risk on hard-to-reach landscapes, restore biodiversity and make it possible to make a living from the land in one of the most expensive states in the country.

Growing your own celery is easier than you think
(LA Times) Jeanette Marantos, Jan. 22
…But for some reason, celery is not a winter garden staple like other greens, and that's a shame, says Gardening in L.A. blogger and master gardener Yvonne Savio. “If you're a cook, you need to grow celery, because you get twice as much as what you buy at the store.”
… You can plant the seedlings in the ground or in a large pot, Savio said. Celery roots range from 18 to 24 inches, according to a vegetable root depth guide prepared by the University of California Cooperative Extension for Los Angeles County, so look for a pot that's as deep as possible, Savio said. “For any vegetable, find the optimum depth and then add another 4 inches to the pot so the roots have some room to grow. You don't want them pushing against the sides of the pot.” Finally, choose a sunny location; celery can't handle high summer temperatures, but during the winter, when days are shorter and the sun less intense, they need at least four to six hours of sun daily.

Northern California Sturgeon Farms
(California Ag Today) Tim Hammerich, Jan. 16
If you've ever had sturgeon, there's a good chance it came from a Northern California sturgeon farm. A conservation success story, sturgeon farming has been commercialized thanks to conservation work started at UC Davis decades ago. Cooperative Extension Aquaculture Specialist Dr. Jackson Gross explains.
Gross..”Sturgeon started off as a conservation story for California, our Sacramento sturgeon or Sacramento white sturgeon over 30 years ago, they started working at white sturgeon conservation here. Part of that was the aquaculture, the role of aquaculture, conservation aquaculture, People understood that sturgeon, in terms of caviar, could also be of a high quality, which also could provide food as well as income to an industry. Um, and that, that started, uh, to what we have today is a sustainable sturgeon industry in the greater Sacramento area.”

Five of the past six years have been the warmest in Bakersfield's recorded history
(Bakersfield Californian) Steven Mayer, Jan. 15
… Daniel Sumner, an ag economist at UC Davis, said researchers across the state are busy studying the changing patterns of California's Mediterranean climate.
"We don't look at the average annual temperature," he said. "It's not that interesting."
When it comes to the effect climate change could have on the Central Valley — California's fruit basket — Sumner said researchers aren't seeing changes in summertime high temperatures. Instead, they're seeing increases in wintertime lows.
The warmer nights are a "big deal," he said.
Not only do warmer nights limit the all-important chilling hours for some of the valley's most valuable crops, it opens the door to damaging pests.

What is killing the native oaks of Southern California?
(San Bernardino Sun) Janet Hartin, Jan. 15
The Goldspotted Oak Borer, or GSOB, is an invasive beetle that is killing native oaks in several areas of Southern California.
Susceptible oaks include coast live oak, canyon live oak, and California black oak. In many cases, GSOB has damaged or killed mature oaks valued for their beauty, wildlife habitat, and shade. Areas with large numbers of native oaks are particularly at risk. Unfortunately, oaks that are injured over several years from multiple generations of the GSOB often die.
California Loses Chlorpyrifos: What's Next?
(CropLife) Jackie Pucci, Jan. 13
…In California, the end of chlorpyrifos “will profoundly impact” alfalfa integrated pest management and pest resistance, according to a blog by Rachel Freeman, Daniel Putnam, and Ian Grettenberger of the University of California Cooperative Extension.
“Unfortunately, alfalfa weevils frequently reach economic damaging thresholds in California, and many growers find it necessary to spray. There are some aphid-specific insecticides (other than chlorpyrifos) that would help with aphids but not with alfalfa weevil,” the authors stated: “Weevil resistance to pyrethroids is beginning to be a problem throughout the western states, including select areas in California, such as the Intermountain and Low Desert production areas. With the loss of chlorpyrifos, the overuse of a single class of insecticide could be a major challenge.”

Chlorpyrifos ban to go into effect
(Farm Press) Tim Hearden, Jan. 13
…Chlorpyrifos historically has been used on a lot of different pests in a lot of different crops,” said David Havilland, a University of California Cooperative Extension entomology advisor and a member of the work group.
“In most cases with chlorpyrifos uses, growers have already switched to other products,” Havilland said. “The effort to find replacements has been going on for more than a decade. But there are about 20 pests in the state for which satisfactory levels of control have been difficult to achieve without the use of chlorpyrifos. That's the focus.”
…The chlorpyrifos ban is a major issue for alfalfa, since it is one of the most popular wide-spectrum insecticides for management of key alfalfa pests, UC scientists Rachael Freeman Long, Daniel Putnam and Ian Grettenberger wrote recently.
These include the alfalfa weevil, Hypera postica, which chews on the foliage, and aphids that suck juices from the plant, the researchers wrote. Though its use has declined, chlorpyrifos was still used on 153,000 acres of California alfalfa hay in 2017, according to the DPR's Pesticide Use Report.
Local ag experts face budget constraints
(Chico Enterprise-Record) Camille Von Kaenel, Jan. 10
Butte and Glenn counties have been going with fewer local experts who can provide agricultural research and advice following budget constraints at the University of California.
…The experts are funded through the University of California Agriculture and Natural Resources division. The state budget for the program has been flat or decreasing over the past two decades. Most recently, the allocated funding stayed the same despite mandatory pay raises amid University-wide budget cuts. That's meant that many positions have been staying empty once vacated and new positions requested by staff have gone unfunded.
Recruitment has just started again for six state-wide positions after a months-long delay, according to an Ag Alert article, but they are not in Butte, Glenn or Tehama counties. The University of California Agriculture and Natural Resources division is also raising money from other sources, like grants and donations, to continue supporting staff.
For years, Death Valley fought a losing battle against wild burros. A nonprofit seeks to change that
(Las Vegas Weekly) Miranda Willson, Jan. 10
…While Meyers' organization emphasizes the humanitarian side of wild burro management, the ecological arguments are equally significant for the NPS. Burros damage vegetation near the park's desert springs, which support rare and endemic fish, plants, invertebrates and insects, Ainsworth says. They also compete with native grass-eating mammals—like endangered desert bighorn sheep—for food and access to increasingly rare watering holes, says Laura Snell, livestock and natural resource adviser at the University of California Cooperative Extension.
“We've seen quite a bit of competition at watering holes throughout Nevada and northeast California,” says Snell, who has studied burros' ecological impacts. “All of those animals need water, and there's maybe only one watering hole available year-round.”

CDFA awards $1.5 million for nutrient management projects
(Farm Press) Jan. 10
The California Department of Food and Agriculture (CDFA) Fertilizer Research and Education Program (FREP) announces more than $1.5 million in grant funds are being awarded to agricultural organizations and universities as a result of the FREP Grant Program 2019 grant cycle.
These grants will fund seven research projects to improve the efficiency of nitrogen (N) fertilization in California agriculture, reduce the associated environmental impacts, and advance farmers' understanding and implementation of best management practices (BMPs) for fertilizer application in farmlands.
Funded Research Projects:
1. Developing a Nitrogen Mineralization Model for Organically Managed Vegetable Farms on the Central Coast – Joji Muramoto, University of California Cooperative Extension.
This project will create a database of organic fertilizers and amendments, crop residues and soil organic matter, cataloguing the rates at which N becomes available as these materials decompose. The principal investigators (PIs) will use this information to develop an N mineralization model for organic vegetable production in coastal California that can be integrated into CropManage, a decision-making tool for irrigation and nutrient management.
2. Immobilization of Nitrate in Winter-Fallow Vegetable Production Beds to Reduce Nitrate Leaching – Richard Smith, University of California Cooperative Extension.
To enhance the process of immobilization during the winter-fallow period in vegetable production beds, this project will study the application of green waste materials that can sequester residual soil nitrate and reducing leaching. This green waste application should stimulate soil microbial activity to keep excess N in the surface layers of soil.
3. Next Generation Nitrogen Management Training for Certified Crop Advisors (CCAs) – Doug Parker, University of California Agriculture and Natural Resources (UCANR).
The goal of this training program is to communicate best N management practices and increase the ability of CCAs to make informed recommendations to growers, thereby improving both environmental quality and crop productivity. This project will develop exam and study materials as well as a video series for the next evolution of the UCANR/FREP CCA Training program.
4. Irrigation and Nitrogen Management, Monitoring and Assessment to Improve Nut Production while Minimizing Nitrate Leaching to Groundwater – Thomas Harter, University of California, Davis.
The efficacy of high-frequency-low-concentration (HFLC) fertilization will be demonstrated in this project under real world conditions as an economically and environmentally promising practice. This work will also compare three water quality monitoring approaches for regulatory compliance.
5. Developing Nutrient Budget and Nutrient Demand Model for Nitrogen Management in Cherry – Patrick Brown, University of California, Davis.
This project will develop nutrient demand curves to guide the quantity and timing of fertilizer application in cherry. Through this work the PIs will develop and extend nutrient BMPs for cherry cultivars.
6. Promoting the Adoption of CropManage to Optimize Nitrogen and Irrigation Use through Low-Cost Data Loggers and Cellular Modems for Spanish-Speaking Growers in Santa Cruz and Monterey Counties – Gerry Spinelli, Resource Conservation District of Santa Cruz County.
The focus of this project is the development of affordable data loggers. These data acquisition devices will be designed to work with the CropManage tool. The PIs will also work closely with growers to increase the adoption of CropManage usage in the Central Coast.
7. Achieving Efficient Nitrogen Fertilizer Management in California Wheat – Mark Lundy, University of California, Davis.
This project will demonstrate best N management practices in California wheat on field-scale plots in combination with site-specific measurements of the soil, plant and canopy to guide real-time N management decisions. The PIs will provide customized decision-support information produced by a dynamic web-based tool and California-specific models.

Placer/Nevada 4-H Program Seeks to Transfer Woodchuck Camp Ownership
(YubaNet) Jan. 6
The Placer and Nevada County 4-H programs are seeking a new owner for a camp facility at Woodchuck Flat on the Tahoe National Forest near Cisco Grove, California. The facility, which includes a well, kitchen, showers, toilets, and tent platforms is operated under a special use permit from the U.S. Forest Service.
“Placer and Nevada County 4-H members have enjoyed the Woodchuck Flat camp for many years,” says Dan Macon, Livestock and Natural Resources Advisor and Co-County Director for the University of California Cooperative Extension, which oversees the 4-H program. “Unfortunately, since we only use the camp two weeks each year, we don't have sufficient funds to pay for upkeep of the facility.”

… The acreage drop reflects the increasing difficulty of producing strawberries amid persistent labor shortages and the elimination of methyl bromide. So growers are gravitating to more prolific varieties developed by the University of California Cooperative Extension, other agencies and private companies.
Among the more popular new varieties are the UC-developed Monterey and San Andreas strawberries, both of which are “day-neutral” varieties that are more tolerant of summer heat and more resistant to diseases.

From Blaze to Bottle: Smoke gets in your wine
(Wine Business Monthly) Glenn McGourty, Jan. 1
The River Fire started around noon on a hot and breezy day July 27, 2018 on Old River Road between Hopland and Ukiah in Mendocino County about 150 yards from the Russian River. Bright orange flames moving quickly up the hillsides along the road igniting the dry vegetation, sending up huge clouds of smoke. The fire spread rapidly east with prevailing winds into steep brushy terrain with little road access hindering fire fighters from stopping its spread. Almost simultaneously, the Ranch Fire began just to the north along Highway 20 near Potter Valley burning very fast north and east to Lake County. The two fires were named the Mendocino Complex Fires, and by the time they were official over on October 4, 2018, they had burned around 450,000 acres making it the largest wildfire in California history (Cal Fire Incident Reports).
An airborne fungus from Europe, ganoderma adspersum, has been killing almond trees in the San Jaoquin Valley since it was discovered in the area five years ago, reported John Cox in the Bakersfield Californian.
The fungus rots wood from the inside out, usually weakening the trunk a ground level.
Three kinds of ganoderma fungus infections were identified recently in California almond orchards; University of California researchers say 94 percent of the cases were of the adspersum variety.
"We are seeing those trees collapsing at 11, 12, 15 years old,” said UC Cooperative Extension orchard systems advisor Mohammad Yaghmour. The infections have results in the removal of orchards at less than half their typical 20- to 25-year life span.
Spraying for the fungal disease is ineffective. Yaghmour believes that in time researchers will identify a root stock that is resistant to the fungus.
The National Park Service has contracted with Peaceful Valley Donkey Rescue to humanely remove 2,500 to 4,000 burros in Death Valley National Park, a particularly challenging effort because the Bureau of Land Management, which manages adjoining land, does not consider the non-native equines a problem, reported Miranda Willson in the Las Vegas Sun.
The rescue organization rounds up the burros and puts them up for adoption.
Experts say the burros damage vegetation near the park's desert springs, which support rare and endemic fish, plants, invertebrates and insects. They also compete with native grass-eating mammals — like endangered desert bighorn sheep — for food and access to increasingly rare watering holes, according to Laura Snell, livestock and natural resources adviser at the University of California Cooperative Extension.
“We've seen quite a bit of competition at watering holes throughout Nevada and northeast California,” Snell said. “All of those animals need water, and there's maybe only one watering hole available year-round.”
Executive director of Peaceful Valley Donkey Rescue Mark Meyers said wild burros are a part of American history that people can experience and preserve by adopting them.
“We used them for the Spanish Trail, we used them for Catholic mission systems, we used them for the railroad, we used them for mining. We used them for all these capacities, and then we said, ‘We don't need them anymore,' ” Meyers says. “These animals built our country, yet they're the ones that aren't supposed to be here.”
