UC ANR horticulture advisor Kabashima to retire after 28 years

John Kabashima
John Kabashima wrapped up his horticultural career on July 1, 2015, after 28 years with University of California Agriculture and Natural Resources. Nursery professionals lauded the UC Cooperative Extension advisor's service to the nursery and landscape industry and to homeowners in Orange and Los Angeles counties.

“He's one of the few people who could translate science into business with a sense of candor and fact-based conversation,” said Robert Crudup, president of Calabasas-based Valley Crest Tree Company, of Kabashima. “John has long-term vision, which he used throughout his career to move the nursery industry forward.”

“He is smart about political science as well as plant science,” Crudup said. On a regular basis, Kabashima would warn growers about emerging issues that were likely to affect the nursery industry, such as regulations to control the spread of polyphagous shot hole borer, red imported fire ant and palm borer.

“He's been very, very valuable,” said retired nurseryman Gary Hayakawa, noting that Kabashima not only contributed research on pest control and water issues for the nursery and landscape industries, but also persuaded people from UC campuses, the California Department Food and Agriculture and industry to work together. “Before he was involved in issues, the work was all separate. Industry didn't have input,” Hayakawa said. “What John has done is to work with all three to form a coalition.”

Crudup, whose company has nursery operations in Los Angeles, Ventura, Alameda and San Joaquin counties, agreed.

“John's biggest contribution was his work with the glassy-winged sharpshooter subcommittee,” said Crudup, who served on the subcommittee. “He brought a voice of reason that helped counterbalance emotional sides of the discussion.”

“His ability to act as the primary liaison between the nursery industry, CDFA, the UC, the county agricultural departments and the wine and grape industries was the primary reason this part of the GWSS (glassy-winged sharpshooter) program was so successful and, more importantly has resulted in the continued viability of the California nursery industry in light of significant regulatory pressures,” said Bob Wynn, who was statewide coordinator of the CDFA Pierce's Disease Control Program and who continues to oversee the program as senior advisor to Secretary Karen Ross.

“The CDFA, with advisement and counseling from John, developed what is known as the Approved Nursery Treatment Program, which allows nurseries in the infested areas of the state to ship by merely treating the plants with an approved treatment,” Wynn said.  “John was the primary author in the development of the nursery ‘Approved Treatment Best Management Practices' document published in 2008. The use of this document has allowed the nursery industry to save millions of dollars in regulatory compliance costs over time.”

A native of Los Angeles, Kabashima says he started working in his family's nursery business as soon as he was tall enough to water 1-gallon nursery plants.  “After killing thousands of plants, I was finally allowed to manage the family business from 1970 to 1976,” he quipped.

Kabashima is an avid photographer. This red palm weevil is one of his most requested photos.
In 1976, his family sold the nursery and Kabashima enrolled at California Polytechnic University, Pomona. After he earned a B.S. in agricultural biology from Cal Poly Pomona in 1979, he was hired by UC Riverside horticulture entomologist Pat Morishita as a lab technician. While working at UC Riverside, Kabashima earned a master's degree in pest management. He would later complete a Ph.D. in entomology at UC Riverside.

Kabashima earned his MBA at Pepperdine University in 1986 while managing the Ornamental Horticulture Division at Target Specialty Products. In 1987, the UC Division of Agriculture and Natural Resources recruited him to become a UC Cooperative Extension environmental horticulture advisor in Orange and Los Angeles counties. 

Over the years, he has studied the management of insects, diseases and weeds in horticulture production systems, biological control of exotic pests, and water-related problems in landscapes, golf courses, nurseries, municipalities and watersheds. 

In 1998 Kabashima took over the fledgling UC Master Gardener Program in Orange County, which as of now has trained more than 300 UC Master Gardener volunteers to extend research-based information on gardening and horticulture to the public.

The UCCE environmental horticulture advisor has also served as director of UC Cooperative Extension in Orange County and interim director of the UC ANR South Coast Research and Extension Center

In 1994, when Orange County filed for bankruptcy and the Board of Supervisors voted to discontinue funding and housing for the local UC Cooperative Extension, Kabashima worked with Gary Hayakawa to keep UCCE in the county. 

“When Orange County cut Cooperative Extension's budget, we found out that without extension you don't have 4-H or Master Gardeners,” Hayakawa said. To preserve the UC Cooperative Extension programs, Hayakawa, who was an Orange County Fair Board member, helped Kabashima secure office space in trailers on the fairgrounds. In 2014, the UCCE office moved from the fairgrounds to UC ANR South Coast Research and Extension Center in Irvine.

Kabashima belongs to many professional organizations including the Entomological Society of America, California Association of Nurseries and Garden Centers, Nursery Growers Association, Western Chapter of the International Society of Arboriculture, United Agribusiness League, and San Diego Flower and Plant Association. The scientist has served on numerous government and industry advisory committees.

Throughout his career, Kabashima's achievements in education and research have been recognized by various organizations. To name a few, he received the 1987 Education and Research Award from the Orange County Chapter of the California Association of Nurseries and Garden Centers (CANGC), 1993 CANERS Research Award from CANGC, 2002 Nursery Extension Agent Award from the American Nursery and Landscape Association, 2008 Western Extension Directors Award of Excellence, 2010 Entomological Society of America's National IPM Team Award and the 2011 California Agriculture Pest Control Advisors Association Outstanding Contribution to Agriculture Award. In 2014, he and his friend Hayakawa were inducted into the Green Industry Hall of Fame.

Being a UCCE advisor has suited Kabashima. “I love learning new things, sharing that information with others, and using my skills to solve problems facing California, such as the ever-increasing arrivals of exotic and invasive pests,” he said. The avid photographer has been able to unite his avocation with his vocation. His photographs of insects have been used to illustrate textbooks, websites and news articles.

“Success in one's field is often a combination of natural ability, informal and formal training and education, being mentored, and networking with collaborators and colleagues, all sprinkled with a little bit of luck and support from one's family and friends,” Kabashima said.

In retirement, Kabashima plans to seek new culinary experiences with his wife Janet and daughter Misa, at home and in their travels together. He has been granted emeritus status by UC ANR and he will continue his efforts to help UC Irvine save trees on its campus that are infested with polyphagous shot hole borer.

UC Berkeley honors Allen-Diaz

Barbara Allen-Diaz receives Berkeley Citation.
For her contributions to UC Berkeley and beyond the University, Barbara Allen-Diaz was awarded the prestigious Berkeley Citation. On behalf of Chancellor Nicholas Dirks, Keith Gilless, dean of the UC Berkeley College of Natural Resources, presented the campus's highest honor to the head of the University of California's Division of Agriculture and Natural Resources on June 19 at her retirement celebration at Lawrence Hall of Science in Berkeley.  

“I am incredibly honored to receive this special award,” said Allen-Diaz, who was visibly surprised and moved by Gilless's announcement.

The Berkeley Citation recognizes academic achievement and University service of the highest order. In addition to her contributions as a researcher, graduate student mentor and professor of range science, Allen-Diaz has served in many leadership roles for UC Berkeley and UC Agriculture and Natural Resources (ANR).

“Her leadership as chair of the Department of Environmental Science, Policy, and Management, as Executive Associate Dean of the College of Natural Resources, and finally as the Vice President for Agriculture and Natural Resources has produced a legacy of accomplishments that few academics can match,” Gilless said. “The college would not have its remarkable Geospatial Innovation Facility without her foresight and willingness to make the necessary investment. ANR would not have the strategic plan that has guided a resurgent sense of how to implement the University's land grant mission.”

Allen-Diaz has served as a member of the Intergovernmental Panel on Climate Change, the National Academy of Sciences and the Association of Public and Land Grant Universities. She has authored more than 170 research articles and presentations. In February, she became the first woman to receive the Society for Range Management's highest award, the Frederick G. Renner Award.

After earning her bachelor's, master's and doctoral degrees at UC Berkeley, Allen-Diaz took a job with the U.S. Forest Service. In 1986, she joined the faculty at UC Berkeley faculty, where she studied the effects of livestock grazing on natural resources, oak woodlands and ecosystems of the Sierra Nevada and the effects of climate change on rangeland species and landscapes. At the end of June, she will retire as UC vice president and as Russell Rustici Chair in Rangeland in the Department of Environmental Science, Policy and Management at UC Berkeley.

The Berkeley Citation was created in 1968, when the University of California celebrated its 100th birthday, to honor individuals or organizations that had rendered distinguished or extraordinary service to the university.

UC ANR leader in Butte County Susan Donohue retires

Susan Donohue, left, brought UC ANR nutrition education to Butte County.
A leader in UC Agriculture and Natural Resources nutrition education in Northern California, Susan Donohue retires July 1 after 38 years of service to UC Cooperative Extension and the community.

Donohue began working in extension after earning a teaching credential at the University of Hawaii and a master's degree in family studies at Michigan State. She was named home economist and 4-H advisor for Butte and Tehama counties in 1978 and held many positions over the years combining 4-H and home economics. "Home economist" was renamed “nutrition, family and consumer sciences advisor” during her career to more accurately reflect the job's scope.

As the nutrition, family and consumer sciences advisor, Donohue was responsible for setting up the first federally funded Expanded Food and Nutrition Education Program in her part of the state. The program provides training to low-income families to help them follow federal nutrition guidelines, including the current iteration, MyPlate. Donohue also established an educational program for CalFresh (formerly food stamp) recipients, called UC CalFresh. The program helps families make the best use of their benefits with meal planning, smart shopping and home cooking, among other strategies.

In time, Donohue was promoted to director of UC ANR Cooperative Extension in Butte County. In that role she helped establish UC Master Gardeners in the region, a program which enlists volunteer gardening enthusiasts to share research-based information with the public on sustainable landscaping, orchards and vegetable gardening. Donohue also was instrumental in attracting a technology transfer initiative to monitor and maintain honey bee health to UC ANR Cooperative Extension in Butte County.

The “Bee Informed Partnership,” created with a $5 million grant from the USDA's National Institute of Food and Agriculture in 2011, identified common beekeeping management practices and developed best practices on a regional level. In addition to involving institutions already doing pollinator work, the partnership included local citizens working in beekeeping and associated industries.

Later in her career Donohue worked on a statewide leadership council for UC ANR's Expanded Food and Nutrition Education Program.

“I really enjoyed the administrative component of the job,” Donohue said. Nevertheless, during the last year of her tenure she returned to the county for a chance to again work directly with local clients and organizations on nutrition education.

“There is no better job than Cooperative Extension,” Donohue said.

In retirement Donohue said she plans to enjoy a slower-paced life, national and international travel and volunteering.

Maxwell Norton, director of UCCE in Merced County, to retire after 36 years

Maxwell Norton
Maxwell Norton, UC Cooperative Extension director and advisor in Merced and Mariposa counties, plans to retire on July 1. Norton, who specializes in tree fruit, grapes and farmland preservation, has served Merced County growers for UC Agriculture and Natural Resources for 36 years.

Norton is “probably the kind of person everyone would like to know – a kind and gentle soul who exudes knowledge and wisdom,” said Bill Martin, executive director of Central Valley Farmland Trust.

For the past 10 years, Martin has worked on conserving farmland with Norton, who was a founding member of the Merced County Farmland and Open Space Trust, which merged with two other land trusts to become Central Valley Farmland Trust.

“He has an understanding of the landscape that is greatly appreciated,” Martin said of Norton. “He's very low-key, observant and provides timely input on provocative issues that come up at board meetings.”

Raised on a farm near Salida, north of Modesto, Norton studied pomology at Fresno State University, earning a B.S. and an M.S. in plant science before joining UC Cooperative Extension.

During his career, the UC Cooperative Extension advisor has helped Merced County growers solve problems in kiwifruit, Asian pears, prunes, peaches, strawberries, figs and pomegranates.

“When I started in 1979, there was rapid growth of two new industries – kiwifruit and Asian pears,” Norton said. “I conducted some early research trials on kiwifruit and authored a chapter of the new UC Cooperative Extension production manual for kiwifruit. I also spent a lot of time diagnosing Asian pear problems.” 

Early in Norton's career, UC scientists introduced a device for measuring soil moisture called a neutron probe.  The young advisor tested the device in peach orchards on clay-loam soils, attempting to correlate the probe, gypsum blocks, tensiometers and pressure chamber data. 

“All of these tools were relatively new then,” said Norton. “Mid-day values had not been established yet so data collection entailed going out at 3 a.m. to pick leaves and measure the leaf water potential while crouching in the back seat of my government-issued Plymouth Fury.”

Over his 36-year career, Norton has worked with kiwifruit, Asian pears, prunes, peaches, strawberries, figs and pomegranates.
Over the years, he has collaborated on many UC Cooperative Extension research projects for processing peaches, including mating disruption for oriental fruit moth. “Growers who farmed near towns were especially desperate for pest management tools that were more acceptable to urban neighbors,” he said.  

Collaborating with his UC Cooperative Extension colleague Roger Duncan in Stanislaus County, Norton conducted several research projects aimed at reducing labor costs in peaches. Projects included mechanical fruit thinning, chemical blossom thinning and various types of mechanical blossom thinning. 

Research by Norton and his fellow Cooperative Extension advisors showed that mature prune trees could be pruned every other year and still produce desirable fruit size and maintain yields. Growers widely adopted the practice of alternate year pruning.  Later, Cooperative Extension set out to demonstrate the new integrated prune farming practices where IPM tools were integral parts of the system.  

In the early 1980s, when many grape growers were spraying pesticides three to four times a year, leafhoppers developed resistance to some insecticides. Norton and other UC experts saw the potential for biological control by the Anagris parasitic wasp.  UC Cooperative Extension advisors persuaded growers to not spray the first or second generations of leafhoppers and let the beneficial insects control the pests. Now grape growers rarely have to spray for leafhoppers. 

Over Norton's career, agriculture in Merced County has diversified. He began having strawberry meetings translated into Hmong or Lao for immigrant growers and studying pomegranates and figs.

Off the farm, Norton has been active in community development, organizing workshops for farmers on how to export their products, chairing the Merced County Economic Development Task Force twice and serving twice as president of the county's Chamber of Commerce.   

“My favorite part of the job has always been doing farm calls, where I went out and visited growers and diagnosed problems, explaining the nature of the problem, and most importantly, suggest things to try,” Norton said.

In retirement, Norton plans on playing his tenor and bari sax in jazz bands, training UC Master Gardeners and volunteering with the local historical society and other organizations.

He has also been granted emeritus status by UC Agriculture and Natural Resources.
