Day has deep roots in Tulare County. He was raised on a Dinuba farm established by his grandfather in 1906, where he farms peaches and nectarines to this day.
With bachelor's and master's degrees from Fresno State, Day launched his UC career in 1985 at the UC Kearney Agricultural Research and Extension Center in Parlier as a staff research associate, working with UC Davis plant physiologist Ted DeJong. With DeJong, Day participated in the development of the “Kearney Perpendicular V,” a high-density tree training and pruning system that brings peach and nectarine orchards into full production at an earlier age.
Determined to climb the career ladder under his own terms, Day waited for the ideal position to be offered by UC in his beloved home county of Tulare. In July 1991, Day joined the Tulare County academic staff as pomology advisor with years of hands-on research experience and established relationships with Kearney- and UC campus-based specialists.
Day is highly regarded as an expert in stone fruit cultural practices. He conducted research to manage light exposure within tree canopies, pruning and training systems, irrigation, fertilization and pest management. He wrote the first published research on summer pruning of stone fruit trees in California and introduced a revolutionary tree fruit orchard establishment practice he termed “benign neglect.”
“Benign neglect changed the way farmers looked at pruning trees in new orchards,” Day said. “We don't prune fruit trees at all in the first year or two. This saves the cost of labor, and brings the tree into production years before new orchards that have been trained and pruned conventionally.”
In addition to many stone fruit growers, almond, walnut and pistachio farmers around the world have been able to cut costs and increase profitability by following this production practice.
In all, Day has written more than 500 papers on tree fruit management, including peer-reviewed articles in scientific journals, magazine articles in popular publications and research reports. His specialty is in presenting practical information to farmers in accessible language, which helped him earn notoriety in national and international stone fruit circles. In 2012, he became the first county advisor or agent to be honored with the National Peach Council's Carroll R. Miller Award, which recognizes “noteworthy research relating to improved marketing and utilization of peaches.”
Day said he greatly appreciated the flexibility his career has afforded, being able to work with growers to respond to problems as they arose and adjust his focus when circumstances changed.
“I could work on a new disease that popped up. I could study developing insect issues,” Day said. “When people were planting apples in the (19)80s and 90s, I was able to study pruning, training, light management and fruit quality in apples.”
In 2015, Day was promoted to director of Cooperative Extension in Tulare and Kings counties. In this role, he has helped shape academic staffing decisions for the local area and mentor newly hired advisors.
Day has been honored with emeritus status by the University of California. In addition to tending his own tree crop farm in Dinuba, he plans to continue work on a sweeping project at Kearney that is being managed as the “orchard of the future.”
With dwarfing rootstocks and pruning advances developed over decades, the orchard has been designed to minimize the need to use ladders for pruning, thinning and harvesting. Keeping farm workers on the ground is safer, and reduces labor costs by 40 to 60 percent, Day said.
In retirement, Day said he also is looking forward to spending more time reading, pursuing his musical interests, fly fishing, hunting and playing with his six rescue dachshunds, a diminutive dog breed that captured his heart 30 years ago.

California-grown alfalfa seed – a crop valued at nearly $1 billion annually – is shipped around the globe, where farmers use it to grow high-quality hay for dairy cows, horses, beef cattle and other livestock.
“Words cannot express the gratitude the industry has for Shannon,” said JD Allen, manager of the Alfalfa Seed Production Research Board. “Her incredible dedication and commitment to the alfalfa seed industry over the years manifested itself in many ways.”
Mueller, who earned a bachelor's degree in plant science at UC Riverside, worked on alfalfa during her studies at Cornell University, where she completed a master's degree and Ph.D. She was educated about alfalfa seed production by expert farmers producing the crop in Fresno County.
Information is widely available to guide production decisions for alfalfa hay, but seed production is more complicated. There is a delicate balance to achieve with irrigation, pest management and pollination. All factors influence each other.
“If you don't align the variables, there are real consequences in terms of yield and seed quality,” Mueller said.
Having learned the complexity of seed production, Mueller conducted research to find solutions to challenges farmers faced. She studied alfalfa seed pollination with leafcutter bees, dodder control, optimizing plant spacing, gene flow and many other topics.
“Shannon Mueller was a strong advocate for California alfalfa seed producers," said Jonathan Reich, global alfalfa breeding lead at Alforex Seeds. "Throughout her career she engaged with alfalfa seed industry stakeholders to identify research priorities aimed to deliver solutions to problems which had the potential to improve productivity, profitability, and sustainability.”
Mueller's work also focused on dry bean, alfalfa hay and honeybee management.
Mueller said she valued the opportunity to choose her own academic path as a UC Cooperative Extension advisor and work on issues that were of importance to the industry.
“I was able to address critical matters, and make changes over time,” Mueller said. “What I started out doing bore little resemblance to my more recent research.”
In 2011, Mueller was named co-director of UC Cooperative Extension in Fresno and Madera counties with viticulture farm advisor Steven Vasquez. Two years later, after his departure, she took the reins herself.
“I've been lucky,” Mueller said. “We have very intelligent, hardworking academics, program professionals, nutrition educators and staff in Fresno and Madera. I've had the opportunity to learn about our nutrition, 4-H and Master Gardener programs. Along with our agriculture and natural resources programs, I see the tremendous value they bring to Cooperative Extension.”
The University of California has honored Mueller with emeritus status. She plans to focus on expanding the Davis-based California Master Beekeeper program to additional sites in San Diego and Fresno. The new program has received a start-up grant from UC Agriculture and Natural Resources and will begin training volunteers to disseminate science-based information about the importance of honey bees, preserving bee health and responsible beekeeping.
Mueller also plans to travel during retirement, beginning with a month-long trip to Ireland this summer. Upon her return, she plans to take up quilting, get back into painting, and spend more time in the Sierra Nevada.
Livestock operations and fresh produce growers in California are among the most highly regulated in the country, but confusion often exists about what each community does to keep our food safe. The California Good Agriculture Neighbors Workshop: The Produce-Livestock Interface Workshop aims to clarify those roles.
Fruit and vegetable growers, livestock owners and others interested in assuring the safety of fresh produce grown in the vicinity of livestock and wildlife are invited to explore collaborative methods that advance food safety.
At locations in the Central Valley and Imperial Valley, food safety scientists, regulators, growers and ranchers will share what they know about the produce-livestock interface and discuss how we can make food even safer.
“Produce and livestock farmers in Southern California won't want to miss this seminar on food safety June 11 at Desert Research and Extension Center in Holtville,” says Jose Luis Aguiar, UC Cooperative Extension vegetable crops advisor for Riverside County. “Come and hear directly from scientists and regulators about the latest research and regulatory news. The agricultural industry is doing its part to be a good neighbor and work collaboratively to make food safer.”
Participants will gain a better understanding of how co-management of neighboring farms can further enhance food safety, reduce potential for fresh produce outbreaks, and limit liability for both growers and ranchers.
In the morning, speakers will cover laws, regulations and practices that already exist to protect food and environmental safety. In the afternoon, participants will break out into groups to examine how these practices can be leveraged.
There will be time for discussion with Ag Innovations facilitating the meeting. Participants will be encouraged to share their experiences and to ask produce safety questions.
The free workshop, subsidized by a grant from the California Department of Food and Agriculture, is being offered in Holtville and Stockton. Lunch will be provided. For more information and to register, visit www.wifss.ucdavis.edu/good-ag-neighbors.

Researchers who have been investigating the impacts of the Camp Fire and other urban fires in Northern California will gather June 4 in Chico to share what they have learned. Members of the public are invited to attend the Camp Fire Water Resources Monitoring and Research Symposium, which will be held at the California State University, Chico Farm located at 311 Nicholas C Shouten Lane, Chico, CA 95928.
“The recent urban fires across California have raised questions about the fire impacts on watershed health, food safety and groundwater,” said Tracy Schohr, UC Cooperative Extension livestock and natural resources advisor for Butte, Plumas and Sierra counties, who is organizing the symposium.
“The Camp Fire Water Resources Monitoring and Research Symposium on June 4 creates a forum for researchers across a broad spectrum of disciplines to share findings from research conducted in Butte County and across the North State.”
“Chico State is partnering with University of California Cooperative Extension to host this educational symposium to help our community understand the impacts of the Camp Fire,” said Kasey DeAtley, Chico State professor in the College of Agriculture. “In a region rich in natural resources and agriculture production, there has been significant interest in the topic of urban fire implications and researchers have been working hard to find answers that will be shared at the symposium.”
The program will start at 9 a.m. and will feature three sessions. The day will kick off with a session titled “First Year Findings,” looking at initial rapid response for water quality, surface water monitoring, groundwater monitoring and more.
The second session is on “Urban Fires Impacts on Food and Agriculture” and will feature research presentations from UC Cooperative Extension on livestock drinking water quality and forage, eggs laid by backyard poultry, fruits and vegetables grown in gardens, and post-fire forest management.
The symposium will conclude with a session on future investigations, with Chico State professors sharing an overview of a comprehensive study underway to understand the impacts of the Camp Fire on water quality and soil health.

People who are interested in using drones for real-world mapping are invited to attend a three-day intensive drone workshop in the Monterey Bay Area. The third annual DroneCamp will be offered June 18-20 by UC Agriculture and Natural Resources' Informatics and GIS Program. No experience with drone technology is needed to participate.
Drone mapping involves taking high-resolution photos with drones and stitching them together with software to make extremely accurate, orthorectified maps. More difficult than videography, it is widely used in agriculture, construction, archeology, surveying, facilities management and other fields. DroneCamp will cover all the topics someone needs to make maps with drones, including:
- Technology - the different types of drone and sensor hardware, costs and applications
- Drone science - principles of photogrammetry and remote sensing
- Safety and regulations - learn to fly safely and legally, including tips on getting your FAA Part 107 Remote Pilot Certificate
- Mission planning - flight planning tools and principles for specific mission objectives
- Flight operations - hands-on practice with both manual and programmed flights
- Data processing - processing drone data into orthomosaics and 3D digital surface models; assessing quality control
- Data analysis - techniques for analyzing drone data in GIS and remote sensing software
- Visualization - create 3D models of your data
- Latest trends - hear about new and upcoming developments in drone technology, data processing, and regulations
On the first day, DroneCamp instructors will discuss drone platforms, sensor technologies and regulations. On the following two days, participants will receive hands-on instruction on flying safely, using automated flight software, emergency procedures, managing data, and turning images into maps using Pix4D mapper and ArcGIS Pro.
Registration is $900 for the general public and $500 for University of California students and employees. Registration includes instruction, materials, flight practice and lunches. Scholarships are available.
This year DroneCamp is being held in conjunction with the Monterey Bay DART (Drones Automation & Robotics Technology), which is holding an industry symposium on Friday, June 21. DroneCamp participants get a $50 discount to attend the symposium.
