Pest control professionals and land managers who resolved this year to take a whack at buffing up their weed control expertise won't want to miss the popular Weed Science School developed by University of California scientists.

The intensive, three-day school is offered Oct. 18-20 at the University Club Conference Center on the UC Davis campus. Twenty-two hours of DPR continuing education credit have been requested for the school, the only one of its kind in the western United States. Enrollment is limited.

Developed by the UC Davis Weed Research and Information Center (WRIC), the school is geared toward public and private professionals involved in consulting, research, development and sales of agricultural chemicals.

The school will emphasize herbicides registered for use in California and important weeds within the state. Participants can expect to come away with a working knowledge of the mode and mechanism of herbicide activity in plants and the fate of herbicides in the environment. Specific topics include weed biology, ecology and seed bank dynamics, as well as herbicide selectivity, resistance and additives. A hands-on laboratory will focus on herbicide symptoms and broadleaf and grass weed identification.

Registration for the Weed Science School is $550, which includes all course materials and lunch each day. An online registration form and additional information can be accessed through the WRIC Web site at http://wric.ucdavis.edu or call Gale PĂ©rez at (530) 752-1748. Accommodations are not included; however, convenient lodging can be found at www.davisvisitor.com.
