The California Weed Science Society met two weeks ago in Monterey. As always, it was an excellent conference with numerous informative sessions across all aspects of weed management in the state.
The first session of the conference “the weed school” focused on hot topics such as drone based mapping, utilizing remote sensing and high-quality imagery to identify plants for robotic and precision-based weeding. It is amazing how advances in technologies are revolutionizing weed control in certain crops! The agenda also devoted time to five presentations focused specifically on glyphosate, which has been a hot topic as of late. Speakers from the state, Cal Poly, UC Riverside, and Bayer presented information related to...

Proper weed management is important for several reason, but in general younger orchards are much more susceptible to the negative impacts of weed overgrowth. The full canopies of mature orchards limit the amount of sunlight reaching the orchard floor, which suppresses the growth of many weed species. Younger trees also have less extensive rooting systems, putting them into direct competition with weeds for water and nutrients. The presence of weeds provides habitat for.../h3>
Why scout for weeds?
While weeds are present in every orchard, there is variation in the weed species composition and density from orchard to orchard. Scouting for weeds is the basis for a good Integrated Weed Management (IWM) plan. Information gathered from weed scouting allows growers to:
- Evaluate the current year's weed control program
- Adjust control practices for the following year
- Discover weed stands and possible resistance before they spread throughout the orchard
- Select the best control option for species of concern, such as:
- Choosing appropriate management...

Looking for Answers as Kochia Rolls Across the West
Kochia is a tumbling weed plaguing growers and ranchers from Central Canada to West Texas.
“It's salt tolerant, heat tolerant, cold tolerant,” said Kent Davis, a crop consultant with Crop Quest in Colorado. “I want to kill the damn stuff, there's no question about it, but you have to admire it at the same time.”
Davis spoke at a recent.../h3>
The U.S. Department of State and the J. William Fulbright Foreign Scholarship Board are pleased to announce that Steven Fennimore of the University of California, Davis, has received a Fulbright U.S. Scholar Program award to work in Uruguay in agriculture. Fennimore will conduct research and teaching at the INIA Las Brujas horticultural field station as part of a project to develop sustainable weed management systems in specialty crops.
Fennimore is a faculty member in the
