The IR4 program conducts a significant amount of research to facilitate registration of pesticides (both conventional and biopesticides) on specialty crops. The program also supports similar work on a range of non-food crops through the Environmental Horticulture program.

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...
