UC Weed Science

Roundup Ready technology incorporates genetic resistance to glyphosate into crops and it's an excellent tool for weed control. Initial screening in the early 2000s found good alfalfa crop safety, and many growers currently rely on glyphosate as the only herbicide.

David E. Bayer, Emeritus Professor in the UC Davis Department of Plant Biology, passed away on January 20, 2024 in Davis, CA. Dr. Bayer earned his B.S and M.S. degrees from Oregon State University and his Ph.D.

Keep an eye out for this potential problem weed in southern California: Stipa capensis. First reported in 1995 in Riverside, this species is native to the Mediterranean and has established in the Coachella Valley of the Sonoran Desert.

Congratulations to UC Davis weed science graduate student Erika Escalona (Fennimore Lab) for winning 1st place in the student poster presentation category at the 2024 California Plant and Soil Conference on Feb. 6-7, 2024 in Fresno, CA.

California rice growers will have a new herbicide available this year: Cliffhanger, manufactured by Gowan Company. The active ingredient is benzobicyclon, which is the same as one of the two active ingredients in the currently registered herbicide, Butte.
