Singh named UCCE tech and innovations advisor for small farms
Manpreet Singh began working on Feb. 15 as a UC Cooperative Extension technology and innovation advisor for small farms and serves Fresno, Kings, Tulare, Madera and Merced counties.
Singh is responsible for testing and evaluating new technologies that can resolve challenges that small farms experience. With a variety of technological advancements becoming available, Singh will help small farms determine the feasibility and economic impact of their options. His role will not only prioritize crop production efficiency, but post-harvest and marketing of crops as well.
A few areas of concern that are top of mind for Singh are weed control and water efficiency. “Weed control is a major part of agricultural operations and a logistical nightmare,” he said. “Since I did a lot of research in irrigation, I also want to help small farms adapt to smart irrigation controllers.”
Singh earned a master's in horticulture, specializing in vegetable science, and a bachelor's in agriculture from Punjab Agricultural University in India. During his master's program, Singh focused his research on hybrid breeding of melons.
After completing his master's, he moved to the United States to join the Ph.D. program at Texas Tech University where he worked as a teaching assistant for Principles of Horticulture labs. His Ph.D. research focused on limited irrigation strategies for vegetable production in West Texas.
“In the past, I did some extension work, but I never had a chance to work directly with the farmers. I'm ready to do some applied research that involves the farmers. So, this job provides me a great opportunity to do those things,” said Singh.
Singh is based out of the Kearney Agricultural Research and Extension Center and can be reached at mansing@ucanr.edu.
Ott to advise growers in Tehama, Butte, Shasta and Glenn counties 
Since the beginning of this year, Jaime Ott has been settling in at UC ANR as the new UC Cooperative Extension orchard systems advisor for Tehama, Butte, Shasta and Glenn counties.
“Officially I am covering walnut, prune, almond and olive in these counties,” Ott said. “But since there is only one other advisor in my office, Josh Davy, the joke is that he covers anything with feathers, fins and fur – and I cover anything with chlorophyll.”
Ott said she hopes to help California agriculture become more robust, profitable and sustainable – economically, socially and environmentally – far into the future.
“I want to help serve as a bridge, communicating the needs of the growers in my area to the researchers on UC campuses to make sure that we are doing the right research, research that will help to move our production systems forward,” she explained.
After growing up in El Dorado County, Ott earned her undergraduate degree in biological sciences from UC Davis. She received her M.S in marine science from the College of William & Mary, and then joined the Peace Corps, through which she worked with farmers in Zambia to raise tilapia.
Since returning from Africa in 2014, Ott has been working in the lab of Greg Browne at UC Davis and pursuing her Ph.D. in the Department of Plant Pathology. Her research has focused on which Phytophthora species are affecting almonds and walnuts in California and the ways the pathogen is introduced into orchards.
“My experience in Zambia really highlighted how powerful information can be, and I want to make sure that California growers have access to all of the practical information that UC and UC Cooperative Extension scientists are generating,” she said.
Ott, based at the UCCE office in Red Bluff, can be reached at njott@ucanr.edu and (530) 527-3101.
Justin Tanner joins UCCE as grape advisor 
Justin Tanner joined UC ANR on Jan. 3 as a UC Cooperative Extension viticulture advisor for San Joaquin, Stanislaus and southern Sacramento counties.
Tanner is responsible for implementing an innovative extension education and applied research program to address high-priority production issues in wine and table grapes including pest, disease, and water management.
Specifically, he supports entry-level growers who are seeking basic viticulture and pest management practices, while providing experienced growers information on new technologies to remain competitive. All producers face mounting pressures from increased regulatory and environmental compliance requirements as well as cost-competitiveness in an increasingly global marketplace.
Tanner attended Colorado State University and earned a Ph.D. in horticulture, focusing on germplasm conservation of temperate fruit trees. He also attended Texas A&M University, where he earned a master's degree in horticulture for citrus virology, as well as a bachelor's degree in agriculture for environmental soil science.
As a postdoctoral scholar in the Department of Viticulture and Enology at UC Davis, Tanner designed and implemented research projects at Oakville Station in Napa County. During his time there, he investigated various factors that affect wine grape production such as examining the effects of cluster thinning and irrigation practices on grapevine red blotch virus-positive vines to evaluate the efficacy of cultural management practices on mitigating virus impact on grape quality and yield. He also conducted trials to identify rootstock and scion combinations as well as trellis systems to optimize production under warming climate conditions.
To understand the needs and challenges of the growers he supports, Tanner is working closely with growers, industry leaders, the Lodi Winegrape Commission and pest control advisers in the region.
“I see the spread of grapevine leafroll-associated virus by the vine mealybug as a huge challenge for grape growers within San Joaquin and Stanislaus counties,” said Tanner. “As vine mealybug reproduces prolifically and spreads easily, controlling this invasive pest will require an integrated pest management approach with a concerted and sustained effort at the community level.”
Tanner is excited to contribute to the success of grape growers and the wine industry using a science-based approach. “The growers and pest control advisers I have already had the opportunity to meet with have been kind, intelligent and hardworking people who I enjoy working with,” he said.
Tanner is based out of the UCCE San Joaquin County office in Stockton and can be reached at jdtanner@ucanr.edu.
