Posts Tagged: Glenn McGourty
After earning a bachelor's degree in botany at Humboldt State and a master's degree in plant, soil and water science at the University of Nevada Reno, McGourty worked as a Cooperative Extension urban horticulturist in Las Vegas. Later he was a lecturer in the Environmental Horticulture Department at Cal Poly, San Luis Obispo, and managed his family's walnut farm in nearby Paso Robles part time.
When McGourty was named a UCCE farm advisor, UC was beginning to endorse a systems approach to sustainable farming.
“I was certainly one of the people who took it to heart,” McGourty said.
In the late 1980s, most grape growers in Mendocino County disked the soil in vineyard rows every year to reduce weeds. Insecticides were applied that kept workers out of the vineyard for three weeks.
“Vineyards seemed pretty barren and not friendly to nature. We had a lot of soil erosion and water quality issues,” McGourty said. “My colleagues and I tried to find solutions that would boost soil organic matter and encourage beneficial insects and mites. One of our landmark research projects was coming up with good cover cropping systems for wine grapes.”
Those practices are widely implemented today, and across California interest in soil health and sustainability continue to grow. McGourty was assigned to also serve Lake County, where wine growers there adopted a strong interest in sustainable wine-growing practices.
“We have the Healthy Soils Program, in which CDFA is paying farmers to grow cover crops and use compost to sequester carbon in the soil. This came out of our research on alternative farming systems conducted in our region,” McGourty said.
Another research interest has been evaluating wine grapes from the Mediterranean region adapted to warm climates.
“After many years of working with ornamental plants, I realized that the plants that do best in California are all from a Mediterranean climate region,” McGourty said. “It made sense for me to look for wine grape varieties that like that climate, too.”
His research included trips to the Mediterranean area where he visited the wine grape varieties he had evaluated in their native habitat. He was invited to speak at foreign universities and conferences in Italy, France, Spain, Portugal, Greece, Brazil, Argentina, Chile and Australia on projects focused on alternative wine grape farming systems, including sustainable, organic and biodynamic farming in California.
McGourty has been honored by UC Agriculture and Natural Resources with emeritus status. As an emeritus advisor, McGourty plans to work on a national online database of wine grape varieties adapted to warm climates. In addition, he will be involved in a Lake County research project conducting a detailed evaluation of Cabernet Sauvignon grapes on multiple clones and rootstocks.
Retirement promises to be busy for McGourty. In March, he received the most votes in the primary election for a position on the Mendocino County Board of Supervisors. He will be immersed in campaigning until the runoff election in November.
Even if the election doesn't go his way, McGourty won't be idle. He manages a 10-acre wine grape and walnut farm on the Russian River, where he farms with the sustainable practices he taught local farmers during his career.
“I am so lucky! I have had one of the best jobs in UC and live in one of the prettiest places in California,” he said.

UC Merced is relaunching its branch of the Blum Center for Developing Economies with a focus on food security for the first two years of the faculty-led effort. Karina Díaz Rios, a UC Cooperative Extension nutrition specialist, and Kurt Schnier, economics professor with the School of Social Sciences, Humanities and Arts, will lead the rejuvenated Blum Center, with administrative help from the Health Sciences Research Institute.
They hope to make the Blum Center a hub for all food-security-related research and outreach on and off campus.
“We want to create a community on campus to address issues of food security,” Schnier said. “We want to help engage students, faculty members and the community to have a direct effect on people's lives.”
Plans include bringing speakers to the campus and community; supporting efforts such as the campus food bank, which serves students and others who don't always have enough food; helping support student researchers such as the students who serve as Global Food Initiative fellows; and facilitating — including through small grants — faculty research centered on food-related topics such as diabetes, communicating about food, and food and social justice issues.
“We're hoping to help translate research into projects that are relevant to the community,” Díaz Rios said.
Merced County's economy is largely based around agriculture, yet many residents do not have adequate access to food or information to help them make healthy choices.
Alec Gerry, UC Cooperative Extension specialist in the Department of Entomology at UC Riverside, is part of a research team honored with the 2016 Experiment Station Section Award for Excellence in Multistate Research. The award, given by USDA National Institute of Food and Agriculture (NIFA), Cooperative Extension System and the Association of Public and Land-Grant Universities (APLU), honors the team for “S-1060: Fly Management in Animal Agriculture Systems and Impacts on Animal Health and Food Safety.”
Flies are serious pests of livestock and poultry. House fly, stable fly and horn fly species are responsible for damage and control costs that reach over $2 billion each year in the United States.
Through this project, the scientists developed new chemical, biological and microbial control methods, such as using adult flies to deliver pyriproxyfen, which disrupts insect growth, to sites where larvae are developing. A new fly trap for controlling horn flies removed between 1.3 and 2.5 million flies from a herd of 150 pastured dairy cows. The trap doesn't use insecticide and costs $1.50 less per cow than traditional chemical-based treatments.
Through research and outreach, they have given producers the information and tools needed to select appropriate control methods and apply them in a timely manner. Studies have shown what kinds of weather events and landscape features support fly population growth, and national surveys have shown where insecticide resistance is present. Effective fly management practices result in increased profits, a higher quality of life for animals, a safer food supply and improved quality of life in residential and recreational areas near animal facilities. Adoption of new non-chemical control methods significantly reduces the use of expensive insecticides, cutting costs for livestock producers and reducing harm to the environment.
Gerry shares the award with colleagues at Auburn University, Cornell University, Kansas State University, Louisiana State University, New Mexico State University, North Carolina State University, the Ohio State University, Oklahoma State University, Texas A&M AgriLife, University of Arkansas, University of Florida, University of Georgia, University of Illinois, University of Massachusetts, University of Minnesota, University of Nebraska-Lincoln, University of Tennessee, USDA-ARS, Washington State University, Central Garden and Pet Co. in Walnut Creek, Calif., and Agriculture and Agri-Foods Canada. The project is supported in part by USDA NIFA.

APLU recognizes one multistate project each year for high scientific quality, the level of collaboration and the professional leadership shown in conducting the project.
A plaque and a small monetary award of $15,000 to support the research project were awarded to the group by the Experiment Station directors on Nov. 14, 2016, at the annual APLU meeting.
DPR honors Virginia creeper IPM team
UC Cooperative Extension,winegrape growers, the Lake County Wine Grape Commission and the Mendocino County Farm Bureau were awarded a 2016IPM Achievement Award by the California Department of Pesticide Regulation for their leadership in protecting crops from Virginia creeper leafhopper.
In 2011, the tiny insect showed up in Mendocino and Lake counties, causing severe losses of wine grapes. By 2014, the new leafhopper had spread across thousands of acres and was devastating vineyards. Some organic growers began using conventional pesticides to stay in business.
Glenn McGourty, UC Cooperative Extension advisor for Mendocino and Lake counties, Houston Wilson, postdoctoral researcher in the Department of Environmental Science, Policy and Management (ESPM) at UC Berkeley, Lucia Varela, UC IPM advisor for the North Coast, Ryan Keiffer, UCCE agricultural technician in Mendocino, Kent Daane, UCCE specialist based in ESPM and located at Kearney Research and Extension Center, and Serguei Triapitsyn, principal museum scientist at UC Riverside, have contributed to the efforts.
UCCE, grower-collaborators, pest control advisers, the Lake County Wine Grape Commission and the Mendocino County Farm Bureau collaborated to provide newsletters, videos and field days to teach growers to recognize the new leafhopper and its natural enemy, a tiny parasitic wasp that lays its eggs in leafhopper eggs. However, the plentiful natural enemies weren't adequately doing their job in Mendocino and Lake counties. Researchers brought in a new, effective strain of the wasps from the Sacramento Valley, which are now reproducing quickly on their host in the lab and are becoming established in the counties. Eventually, the wasp will enable both conventional and organic growers to reduce synthetic pesticides used to combat the new leafhopper.
The 2016 Achievement Awards were presented at a ceremony at the California Environmental Protection Agency headquarters on Jan. 26 in Sacramento.

Last year, the 4-H Youth Development Program and UC Master Gardener Program successfully participated in #GivingTuesday campaigns.
“Our goal for 4-H was to raise $10,000 and we exceeded our goal with donations totaling over $13,000,” said Andrea Ambrose, acting director of Development Services. 4-H programs in 17 counties participated. In Placer County, the robotics team got their friends and family involved to promote #4HGivingConfidence on social media, leading Placer County to collect the largest amount for the 4-H Youth Development Program.
Although not as widely recognized as the shopping events Black Friday and Cyber Monday, #GivingTuesday appeals to people swept up in the spirit of giving at the end of the year.
“#GivingTuesday is a wonderful opportunity for all ANR programs to augment their funding with private donations,” said Ambrose.
A website is being created with links to all of ANR's programs, Research and Extension Centers and extension offices. Donors will be invited to designate the program or location to which they wish to donate. The URL for the #GivingTuesday website will be announced in ANR Update soon.
ANR will provide a toolkit for county offices and programs to participate. It will include:
- A customizable letter to send to stakeholders
- Templates for “unselfies.” Donors may take photos of themselves holding an unselfie sign and share on social media how they are giving.
- Sample tweets and social media posts
- Sample thank you note
“We focused on fostering a good dialogue and facilitating co-learning among attendees,” said event co-chair Leslie Roche, assistant UC Cooperative Extension specialist in rangeland management. “We hosted university faculty, statewide CE specialists and academics, and county-based CE advisors—as well as local policymakers and leaders from non-governmental organizations and statewide programs.”
UC researchers who have successfully engaged in the public policy arena provided numerous models of linking research and policy. There were five key take-aways for scientists:
- Honest broker role – Present policymakers with various policy options, based on sound research. Have a clear understanding of the science behind your messaging. Use qualitative data to tell the story of the hard quantitative data.
- Active engagement – Be part of informational and oversight hearings. Empower communities to take action and foster community engagement.
- Build coalitions – Collaboration is imperative. Develop unexpected allies and foster long-term relationships, realizing it may take some time to bear fruit.
- Disseminate information – Share your data in user-friendly formats. Target local community, Legislature and state agencies to inform policies. Get your science into trainings and continuing education programs. Leverage your coalition to expand the circulation of your research results.
- Target messages – Develop a strong, concise message to deliver your research. Use an emotional connection – “Old-growth oak woodlands” versus “oak woodland.”
Throughout the conference, speakers highlighted the multiple levels of engagement for researchers in the policy arena, with different roles matching different needs – some take a center stage, while others play imperative behind-the-scenes roles.
Keynote speaker Jason Delborne, associate professor of science, policy and society at North Carolina State University, encouraged engaging the public. “Science is a social process,” he said, noting that community and public engagement is often key to successfully applying research to policy. Delborne also touched on the tension between expertise and democracy, commenting that we can't always resolve it and often we have to learn to live with this tension.
A diverse set of researchers shared their perspectives from experiences in engaging in policy. The panel included Thomas Harter, Robert M. Hagan Endowed Chair in Water Management and Policy and UCCE specialist in the Department of Land, Air, and Water Resources at UC Davis; Lorrene Ritchie, director of the UC ANR Nutrition Policy Institute; Mindy Romero, founder and director of California Civic Engagement Project at UC Davis Center for Regional Change; and Yana Valachovic, UCCE forest advisor and county director in Humboldt and Del Norte counties. They discussed the importance of building strong science-based programs, actively engaging local communities and building coalitions of support.
Guests from both government and non-government organizations who use research to shape policy shared their perspectives on translating science to decision-making.
“Science is the foundation for developing programs,” said Amrith Gunasekara, science advisor for the California Department of Food and Agriculture.
Tina Cannon Leahy, attorney with the State Water Resources Control Board, noted that policymakers and decision-makers are often looking for a clear, “black-and-white” answer, while for scientists, there is “no answer,” but rather information.
Anne Megaro, consultant to the California Senate Committee on Agriculture, and Rebecca Newhouse, consultant to the California Senate Environmental Quality Committee, both emphasized the importance of making sure science is accessible and digestible.
Juliet Sims of the Prevention Institute explained how her organization uses both published scholarly literature and community stories to effectively inform its advocacy platform.
Keynote speaker Rachel Morello-Frosch, associate professor in the Department of Environmental Science, Policy and Management at UC Berkeley, introduced the concept of moving from “translational research” to “transformational research,” a shift that requires deep community engagement in meaningful ways to effect policy change.
In the afternoon, four breakout sessions were offered: “Policy structures and opportunities for engagement” with Robert Waste, “Relational approaches to science communication and engagement” with Faith Kearns, “Putting it into practice–UC ANR case studies” with Dave Campbell, Clare Gupta and Lucas Frerichs, and “Navigating policy engagement: Education vs advocacy,” with Adrian Lopez and Kit Batten. These training modules helped participants build technical skills and analytical frameworks for successful policy engagement.
The Research to Policy Conference was a forum to exchange ideas and share perspectives, continuing to bridge the gap between science and policy communities. It challenged attendees to be open to new ways of thinking, shared innovative outreach methods and showcased how research can have an impact in the policy arena.
“The event brought cross-fertilization and co-learning between disciplines – nutrition, forest management, water quality – and there were common themes that resonated for all participants,” said event co-chair Gupta, assistant UCCE specialist in public policy and translational research.
VP Glenda Humiston wrapped up the policy conference by saying, "Good science is vital for good policy. It's great to see UC folks enhancing these skills to bring science together with policy."

Pourreza wins international prize for HLB detection
Newly appointed UC Cooperative Extension agricultural engineering advisor Alireza Pourreza has been awarded the 2016 Giuseppe Pellizzi Prize by the Club of Bologna, an honor presented every other year to the best doctoral dissertations focused on agricultural machinery and mechanization. The Club of Bologna is a world taskforce on strategies for the development of agricultural mechanization.
Pourreza, who earned his Ph.D. at the University of Florida in 2014, worked on early detection of Huanglongbing disease of citrus. Huanglongbing, an incurable disease that is spread by Asian citrus psyllid, has seriously impacted citrus production in Florida. The disease has been found in commercial and residential sites in all counties with commercial citrus.
Early detection allows growers to remove infected trees before the disease can spread to healthy trees. Currently HLB infection is confirmed when leaves with yellowing blotches are submitted for PCR testing, which is expensive and time-consuming. However, the yellowing can be also symptomatic of other conditions, such as nutrient deficiency.
"We discovered we could see the symptoms of Huanglongbing using a camera, a set of cross-polarizers and narrowband lighting before it is visible to the human eye," said Pourreza, who is based at the UC Kearney Agricultural Research and Extension Center in Parlier.
He said the yellow blotches on HLB-infected leaves are caused by starch accumulation.
"If we could detect abnormal levels of starch in the leaf, we could tell it is affected with HLB," Pourreza said. "Starch showed the ability to rotate the polarization plane of light. We used this optical characteristic to develop the sensing methodology."
Pourreza said the team has patented the technique and is working on developing a commercial product. He is seeking funding to continue the research in California, where, to date, HLB has only been detected in isolated Los Angeles neighborhoods. Asian citrus psyllid is found in important California commercial citrus production regions from the Mexican border to as far north as Placer County.
4-H Youth Development team wins national diversity award
4-H Youth Development advisors Dorina Espinoza, Russell Hill, Fe Moncloa and Keith Nathaniel and 4-H associate director Shannon Horrillo have won the National Extension Diversity Award for systematically enhancing the intercultural competency of 4-H personnel and others in California.
The award, given by USDA National Institute of Food and Agriculture (NIFA), Cooperative Extension System and the Association of Public and Land-grant Universities (APLU), honors the team for creating and using Intercultural Development Inventory© to shift organizational culture. This shift includes mutual respect, acceptance, teamwork and productivity among diverse people.
To meet the needs of a culturally and ethnically diverse youth population in California, they created a professional-development intervention for 4-H academics and staff. The Intercultural Development Inventory© is a cross-culturally generalizable, valid and reliable assessment of intercultural competence. Calling themselves the Intercultural Development Inventory Qualified Administrators, they applied the strategy over three years, providing 176 hours of intercultural communication feedback sessions, learning communities and regional conferences to enhance the intercultural competence of 65 4-H personnel.
Evaluations demonstrated that after the intervention UC 4-H Youth Development Program personnel had acquired skills and characteristics to become more culturally competent. The program has moved from focusing on similarities across diverse people that can mask deeper recognition of cultural differences to recognizing the complexity of dimensions of diversity.
The action plan and resulting positive change provides the potential to improve hiring and professional development nationwide by replication in other states. A summary of California's IDI professional development activities can be found in the National 4-H Latino Youth Outreach: Best Practices Toolkit, Professional Development.
The National Extension Diversity Award will be presented on Nov. 13 at the 129th APLU Annual Meeting in Austin, Texas.
