Weeds are a pervasive and expensive problem in California. They can choke waterways, crowd out native species on rangeland, and rob farmers of crop yields. According to the California Invasive Plant Council, the annual cost of invasive plant work in California is at least $82 million.
The University of California has robust educational resources to help those engaged in the battle, and this summer UC Davis and UC Agriculture and Natural Resources personnel are offering a trio of programs to help in the effort.
Weed Day: July 7, 2016
The 60th annual Weed Day will be held at UC Davis on July 7 from 8 a.m. to 4:30 p.m. The program gets under way in the Buehler Alumni Center.
Weed Day will be of interest to pest control advisers, chemical company cooperators, faculty, students and regulatory officials. It is an opportunity to learn about the latest research and to visit current weed-control field trials. The event begins with a bus tour to the research plots. Following lunch, staff and students will present information on projects that are either not in-season or located too far off campus for viewing.
“We have tomatoes, walnuts, and almonds, as well as aquatic research results, and a weed identification quiz,” said professor and UC Cooperative Extension specialist Kassim Al-Khatib, chair of this year's event. “We'll be hearing about control of medusahead, management in grapes, a new herbicide for rice, and many studies on herbicide resistance issues.”
Diagnosing Herbicide Symptoms: July 8, 2016
The Weed Research and Information Center at UC Davis is offering a new course, Diagnosing Herbicide Symptoms, on July 8 at the Bowley Plant Science Teaching Center.
This program will be of interest to pest control advisers, chemical companies, field investigators and insurance adjusters. The course focuses on how an herbicide injury situation can arise, what information can help diagnose herbicide problems during field investigations, and what tools are available.
Topics include herbicide modes of action, symptom development, recovery from herbicide injury, economic damage, and other areas. Instruction takes place in a lecture, field visit, and hands-on demonstrations. Course instructors include UC Cooperative Extension (UCCE) specialists Kassim Al-Khatib and Brad Hanson, UCCE farm advisor John Roncoroni, and Napa County Agricultural Commissioner Greg Clark.
Aquatic Weed School: Sept. 7–8, 2016
The Aquatic Weed School will be held Sept. 7–8 at the Bowley Plant Science Teaching Center.
This intensive course is designed for those involved in consulting, research and management of aquatic weed systems throughout the western United States. Topics include ecological classification and impacts of aquatic weeds, biology of aquatic weeds, physical and chemical characteristics of aquatic ecosystems, regulatory issues, developing an aquatic management plan, aquatic weed identification, equipment demonstration, adjuvants and surfactants for aquatic systems, pest prevention for aquatic weeds, physical and mechanical control methods, biological control, chemical and non-chemical control, and a case study of a complex management plan.
