Lund named grape advisor for Madera, Merced and Mariposa counties

Karl Lund joined UCCE on Jan. 8, 2018, as an area viticulture advisor in Madera, Merced and Mariposa counties.

Prior to joining UCCE, Lund was a trial specialist at Syngenta Flower, where he designed and conducted floriculture research trials under both greenhouse and garden conditions for a wide variety of flowering plants, specifically focused on the development of fertilization recommendations and nutrient profiles. In 2016, Lund was a technology development representative at Monsanto, where he worked with seed distributors and local farmers to plant, maintain and evaluate pre-commercial varieties of lettuce, bell peppers and spinach.

Lund spent many years teaching and conducting research in viticulture. Starting in 2008, he worked in the laboratory of Andy Walker at UC Davis, where he ran a project looking at the phenotypic and genetic diversity of phylloxera in Northern California, and trying to understand the genetics of phylloxera resistance in hopes of breeding new phylloxera resistance rootstocks for California.  His research helped identify new feeding types of phylloxera in Northern California and connected those feeding types to genetic groups. He also identified new sources of broad phylloxera resistance to be used in breeding phylloxera-resistant rootstocks.

As a postdoc in the Walker lab, Lund looked at drought avoidance in grapevine rootstocks. Insights from this work may be useful in the creation of more drought-tolerant rootstocks. In addition to his research, he was a teaching assistant for several UC Davis classes. Lund wrote a book chapter on grapevine breeding in the western United States and lectured at Cal Poly SLO for the 2015-2016 academic year.

Pourreza wins ASABE Sunkist Young Designer Award

The American Society of Agricultural and Biological Engineers has selected Ali Pourreza, UC Cooperative Extension specialist in the Department of Biological and Agricultural Engineering at UC Davis, to receive the Sunkist Young Designer Award.

This award recognizes and honors ASABE members under 40 years of age for outstanding contributions to the advancement of the agricultural engineering profession and to stimulate professional achievement.

Sponsored by Sunkist Growers, Inc., the Young Designer Award recognizes the development of a technical plan that influences agricultural engineering progress, as evidenced by use in the field.

Pourreza developed a polarized imaging technique to detect accumulation of starch in citrus leaves as an early indication of citrus greening disease or huanglongbing (HLB).

“The polarized imaging technique was primarily used for early citrus greening detection, that is a major disease of citrus with no known cure,” said Pourreza. “Early detection of citrus greening is important because growers can prevent further spread of the disease before the entire orchard gets infected. The polarized imaging technique can also be used in other applications that involve the detection of starch or sugar.”

He also developed the Virtual Orchard, which uses aerial imagery and photogrammetry to create a 3-D image of an orchard.

“Knowledge about tree geometry such as individual canopy cover, volume, height and density is important for growers to understand variability within their orchard and make timely decisions about irrigation, nutrient, pest and disease, etc.,” Pourreza said. ”Virtual Orchard is an affordable technology that makes this information accessible for growers. Information extracted from the Virtual Orchard can be used to apply variable rate inputs in a site-specific manner according to the prescription maps that identify the application rate at different locations of an orchard.”

The award will be presented to Pourreza during the ASABE annual meeting in July in Detroit.

UC ANR receives award for extending high-speed broadband

The nonprofit organization CENIC has awardedUC ANR its 2018 Innovations in Networking Award for Broadband Applications. The award recognizes work to extend high-speed broadband to University of California researchers in rural communities across California by connecting UC ANR sites to the California Research and Education Network (CalREN),

Gabe Youtsey, chief innovation officer; Tolgay Kizilelma, chief information security officer; and Tu Tran, associate vice president for business operations, were recognized as project leaders.

In 2016, CENIC began working with UC ANR to connect its nine research and extension centers to CalREN, equipping them with internet speeds comparable to those found on UC campuses. For example, the UC Hopland Research and Extension Center in Mendocino County and the UC Desert Research and Extension Center in Imperial County are both connected at 500 Mbps, five times their previous level of connectivity. 

“You can't do big data with dial-up internet speed,” said Jeffery Dahlberg, director of the UC Kearney Research and Extension Center. “Before this upgrade, our internet was slower than my home internet speeds. Now we have speeds more like you will find on UC campuses.”

Due to the remote location of most of these facilities, the work involved in identifying suitable pathways for connections between each site and the CalREN network has been extensive. Engineers from CENIC and UC ANR collaborated on network design, deployment, and troubleshooting to equip these facilities with the high-speed internet they need.

In addition to the RECs, Highlander Hall, home to News and Information Outreach in Spanish and the Citrus Clonal Protection Program, is now connected to CalREN. Elkus Ranch (the environmental education center for Bay Area youths), the UC ANR building in Davis and 30 UC Cooperative Extension sites are in the process of being connected.

ANR participates in World Ag Expo

The 50^th World Agricultural Expo was held Feb. 14-16, 2017, in Tulare. The three-day show was attended by 105,780 people representing 43 states and 71 countries, according to its website. UC ANR participated by hosting a newsmakers event for journalists and sponsoring four booths displaying information about the division's array of research and programs.

At the booths, 4-H members and UC ANR scientists greeted visitors and answered questions. Visitors were invited to take a picture with a UC ANR frame and post it to social media with the hashtag #UCWorldAg to be entered in a contest to win a FitBit.

On the first day of the show, reporters were invited to meet UC ANR scientists, who gave 3-minute descriptions of their research. Rose Hayden-Smith, editor of the UC Food Observer blog, was the emcee. The speakers were as follows:

• Mary Lu Arpaia, UC Cooperative Extension horticulturist, UC Riverside, based at the Kearney REC in Parlier,avocadoes
• Khaled Bali, UCCE irrigation water management specialist, based at KREC, automated irrigation systems
• Peggy Lemaux, UCCE plant genetics specialist, UC Berkeley, and Jeff Dahlberg, KREC director and UCCE specialist, plant breeding and genetics, $12.3 million study on sorghum
• Lupita Fábregas, UCCE 4-H Youth Development advisor and assistant director for diversity and expansion, outreach to Latino communities
• Maggi Kelly, UCCE specialist and director of the UC Statewide Informatics and Geographic Information Systems program, UC Berkeley, research using drones
• Doug Parker, director, UC California Institute for Water Resources, drought
• Alireza Pourreza, UCCE agricultural engineering advisor, based at KREC, early detection of huanglongbing disease in citrus
• Leslie Roche, UCCE rangeland management specialist, UC Davis, drought management on rangeland
• Samuel Sandoval Solis, UCCE specialist in water resources, UC Davis, groundwater management

UC ANR and UC Food Observer live-streamed the talks on Facebook Live and on Twitter via Periscope. UC Food Observer's Facebook video of the event has been viewed nearly 5,000 times.

On the second day of the expo, a seminar on the changing role of women in agriculture was presented by VP Glenda Humiston, CDFA secretary Karen Ross and president of American AgriWomen Doris Mold. The speakers noted that women have always been involved in agriculture, but cultural bias often left them feeling that their role was inferior to the roles of male family members. The USDA's next census of agriculture will have questions designed to count women as industry workers even if they might consider their husbands or fathers to be the primary operators of the farm.

Humiston told the audience there are many career opportunities for women in agriculture, not just on the farm. She encouraged the young women and girls in the audience to look for opportunities in allied industries. For career advancement, women can join professional organizations and serve on committees, take advantage of training programs and run for leadership positions.

The panelists suggested that women also identify mentors — both men and women — who can help steer young professional women into successful agricultural careers.

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 129^th APLU Annual Meeting in Austin, Texas.
