Nineteen UC academics – including UC Cooperative Extension county advisors, UC Cooperative Extension specialists, and leaders from University of California Agriculture and Natural Resources (UC ANR) – will make half-hour presentations on the hour from 10 a.m. to 3 p.m. over the course of the three-day show. All presentations will be inside a heated tent at space K50, just east of Pavilion B.
UC Cooperative Extension was established by an act of Congress in 1914 to help farmers, homemakers, and youth incorporate the latest university research into their lives. At first geared towards strengthening rural areas, UC Cooperative Extension has become integral to urban and suburban communities as well. A century later, UC Cooperative Extension advisors and researchers live and work in every California county and partner with local communities to solve economic, agricultural, natural resource, youth development and nutrition issues. Throughout 2014, UC Cooperative Extension will host special events to celebrate the organization’s 100 years of science and service. The centennial kicks off with the speakers’ series at the World Ag Expo, the world’s largest agricultural exposition.
“Conducting research and providing practical information to farmers and the general public are the hallmarks of UC Cooperative Extension,” said Marissa Stein, UCCE centennial coordinator. “We will be celebrating our centennial by doing what we do best – extending information that benefits communities and local economies in California.”
The theme for UCCE centennial presentations on opening day, Feb. 11, is “The good, the bad and the ugly: Species in California,” which focuses on species that benefit and imperil agriculture and urban landscapes. Speakers will discuss the use of natural enemies to control pests, insect problems that have been introduced into California from other countries, and the imminent threat of Asian citrus psyllid to the state’s commercial citrus-producing areas. The mystery of honeybee colony collapse disorder and the perennial menace of pocket gophers and squirrels will also be addressed. Bill Frost, associate vice president of UC Agriculture and Natural Resources and a rangeland management expert, will speak about introduced species that threaten California’s prized wildlands.
Presentations on the second day of the show, Feb. 12, focus on “Wholesome food for a hungry planet.” Featured speaker Barbara Allen-Diaz, UC vice president for Agriculture and Natural Resources will speak at 11 a.m. about “Building on UC ANR research to help feed the world.” Other topics that day will be emerging diseases affecting landscapes and orchards, tracking pathogens in the fresh produce industry, using World War I gardens as a model for modern food systems, and incorporating a healthy local food into the diet.
The final day of the show, seven UC presenters will address the theme “Sustainable is attainable.” The experts will discuss such critical current topics as nitrate and groundwater management, the potential for producing biofuel from California crops, and the adoption of new conservation systems that will revolutionize row crop production in the San Joaquin Valley. Current research findings on cotton production, weed management and air pollution sources round out the day’s offerings.

The Fogarty family has been in the cattle ranching business in Stanislaus County since the 1870s. In recent years, they’ve seen rangeland around them converted to housing and orchards. “With the conversion around us, we are affected with a declining water table, increased traffic and rural crime associated with high production agriculture,” said Bill Fogarty.
Ranchers, researchers, managers, agency representatives and conservationists will gather in January to discuss challenges and opportunities in maintaining rangelands.
Keeping rangelands and ranches viable for wildlife, wetlands and water will be discussed at the 9th annual California Rangeland Conservation Coalition Summit set for Jan. 21-22 at the Gene Bianchi Community Center in Oakdale, 16 miles northeast of Modesto. The summit is sponsored by the California Rangeland Conservation Coalition and the University of California Cooperative Extension.
“This event is a time for ranchers to showcase their positive role in stewarding California’s wide open spaces and their contributions to the state’s economy,” said Tim Koopmann, president of the California Cattlemen’s Association. “Ranchers who attend the annual event learn valuable information on the latest research outcomes about best management practices for their land that simultaneously improve the natural resources and economic profitability.”
At risk is the future of California’s ranching industry and the ecosystem services that ranches provide: diverse wildlife, unique wetlands and healthy watersheds. At the rangeland summit, ranchers, researchers, land managers, agency representatives and conservationists will focus on rangeland science, land management, land-use policy and livestock production.
The event will feature presentations on the challenges ranchers face, impacts of rangeland conversion to natural resources and opportunities to support working ranches and rancher stewardship. Ranchers from Colorado and Montana will share new opportunities they are finding to keep ranching viable through conservation efforts.
The first day of the two-day summit will feature presentations and a ranch tour on the second day.
“University of California Cooperative Extension is pleased to be a partner in bringing together a diverse group of people interested in rangelands to discuss the opportunities and challenges for keeping California’s ranches working to support communities and habitat,” said Theresa Becchetti, UC Cooperative Extension advisor in San Joaquin and Stanislaus counties. “We are particularly fortunate to be able to hold this meeting and engage in a constructive dialogue with stakeholders in Oakdale, where rangelands and associated resources are at risk.”
This event is sponsored by University of California Agriculture and Natural Resources, Environmental Defense, Audubon California, California Association of Resource Conservation Districts, California Cattlemen’s Association, California Native Plant Society, California Rangeland Trust, Santa Clara County Open Space Authority, Center for Natural Lands Management, Defenders of Wildlife, Cal-Pac Chapter Society for Range Management, East Bay Regional Park District, Grazing Lands Conservation Initiative - California, Natural Resources Conservation Service, US Fish and Wildlife – Partners Program, Mid-Peninsula Open Space District, Point Blue Conservation, Sierra Business Council, Sierra Nevada Conservancy, Sustainable Conservation, InterWest Insurance Services, Inc., The Nature Conservancy, Koopmann Rangeland Consulting, and Westervelt Ecological Services. In addition, Oakdale Cowboy Museum and numerous private ranchers are sponsors, hosts and speakers.
The event is open to ranchers, researchers, land managers, agency representatives, conservationists and others interested in California’s rangelands. Journalists are encouraged to attend the event.

The California Rangeland Conservation Coalition is a group of over 125 agricultural groups, nonprofit organizations, researchers and government agencies representing a broad cross-section of California’s ranching and environmental communities. The disparate groups are united by their recognition of the importance of California’s working rangelands for natural resources, plant and wildlife species, cultural values and economics. The Rangeland Coalition began in 2005 with a small group of organizations committed to protecting rangelands within California’s Central Valley and Interior Coast ranges. www.carangeland.org

Daane and his research associates followed moth populations in organic and conventional fields to document this observed change and determine if there were any specific causes for increases in raisin moth densities. In a 2013 season study, UC Kearney Agricultural Research and Extension Center entomologists found that spring to early summer pheromone trap catches of raisin moths were prevalent across numerous vineyards, regardless of management practices. However, overall seasonal damage in 2013 was low.
“The primary difference between vineyard sites with or without raisin moth damage appeared to be well-timed and effective insecticide sprays,” Daane said. “One problem for organic sites may be the availability of insecticide materials that have long enough residual activity to control the larvae of adult moths entering the vineyard, and once the larvae are deep inside the grape cluster they are difficult to control.”
In addition to Daane’s report, the San Joaquin Valley Grape Symposium includes the following research updates:
- Rootstocks for raisin production by Sonet Von Zyl, Fresno State University
- Raisin production canopy management by Matthew Fidelibus, UC Cooperative Extension specialist in the Department of Viticulture and Enology at UC Davis, based at the UC Kearney Ag REC in Parlier
- Raisin grape breeding program by Craig Ledbetter, USDA Agricultural Research Service, based in Parlier
- Economics of producing raisins, by Annette Levi, Fresno State University
- Grapevine trunk diseases and grower survey
The symposium begins with registration at 7 a.m. and concludes following lunch at 1 p.m. at the C.P.D.E.S. Hall, 172 W. Jefferson Ave., Easton, Calif.
Registration is $15 in advance and includes lunch. Registration at the door is $20. To preregister, send the names of attendees and a check payable to UC Regents for $15 each to San Joaquin Valley Grape Symposium, 550 E. Shaw Ave., Suite 210-B, Fresno, CA 93710.

Called the CAHFS Backyard Flock program, this service is funded by the California Department of Food and Agriculture as a biosecurity measure.
"Urban chicken owners generally aren't trained to recognize to recognize signs of illness, there are few if any chicken vets in the city, and online forums are not moderated by experts," says CAHFS researcher Sarah Stinson, lead author of the article.
The study showed that Backyard Flock submissions rose nearly fourfold between 2007 and 2012. Chickens accounted for 91 percent of submissions, and the greatest increases were in Santa Clara, Los Angeles and Sonoma counties. Diagnoses revealed that the birds' digestive and hemolymphatic systems were most commonly affected, and that the most common illness was Marek's disease, a highly contagious virus that can kill up to 80 percent of infected birds.
However, only an estimated 2 percent of amateur poultry keepers are aware of and have used the Backyard Flock program. To decrease the biosecurity risk of infectious diseases in backyard poultry, the researchers recommend advertising this disease testing service as well as reliable information about keeping backyard flocks healthy. For example, backyard chicken websites and online forums could be invited to add links to government websites, programs and information.
Besides keeping their flocks disease-free, people should keep hens in coops that protect them from cats and other urban predators, and give them specially formulated chicken feed from feed stores rather than chicken scratch or scraps. Moreover, even where chickens are legal, it's a good idea to talk to the neighbors before setting up a coop. Ways to earn goodwill include keeping hens in the coop until neighbors are awake, sharing eggs and, most of all, forgoing roosters, which can crow loudly day and night.

Testing protocol ensures the authenticity of organic fertilizers
After major "organic" fertilizer suppliers were found using cheaper inorganic compounds, the state gave the California Department of Food and Agriculture the authority to verify organic fertilizers starting in 2010. But there has been no good way to test whether fertilizers are actually organic. Now, UC researchers have developed an inexpensive method for distinguishing organic from synthetic fertilizers. This method assesses N15, an isotope of nitrogen that is relatively high in organic sources; ammonium, which is relatively low in most organic sources; and the ratio of carbon to nitrogen, which has a characteristic value for a given organic source.
Soil type, crop and irrigation all influence optimal nitrogen management
Groundwater can be contaminated by nitrate, and most of this contamination comes from fertilizer applied to crops. It makes intuitive sense to address this problem by managing nitrogen on farms, and this is the approach recommended by the California State Water Resources Control Board. However, new research shows that nitrate levels in groundwater are also affected by soil type and rainfall, which cannot be managed, as well as by irrigation and crop type, which can. Rather than focusing solely on nitrogen management, the researchers call for best management practices that also include irrigation management and that can be tailored individually to farms.

“With our administrative and statewide program staff co-located in one building in Davis, we will be able to work more efficiently to meet the needs of Californians statewide,” said Allen-Diaz. “We also anticipate savings on energy and other costs by renovating an existing building to meet LEED Certified Interior standards.”
Originally built as an indoor roller hockey rink, and later used as the temporary home of the Yolo County Library and the Explorit Science Center, the building will become the administrative home for UC ANR’s statewide programs. Interior renovations to the existing 33,000 square feet include adding 9,600 square feet of a partial second floor in the rink portion of the building.
UC ANR’s statewide programs include Cooperative Extension advisors located in 57 counties as well as nine Research and Extension Centers in different ecosystems from Tulelake near the Oregon border to El Centro in the Imperial Valley. UC ANR also manages a number of well-known statewide programs whose administrative offices will be located in the new building, including:
- Integrated Pest Management;
- Master Gardeners;
- 4-H Youth Development; and
- The Expanded Food and Nutrition Education Program (EFNEP).
