The latest information on weed control will be presented at the Weed Management in Agronomic Crops for a Changing Environment online event on Monday, Nov. 15, 2021 from 9:00 AM-12:00 PM (Pacific Time.) The lineup of UC Cooperative Extension (UCCE), UC Davis and Fresno State experts will discuss why we see horseweed and hairy fleabane in most parts of California year-round, herbicide trials in drill-seeded rice, integrated weed management for water-seeded rice, Italian ryegrass control in small grains, cover crops and weed management, and alternatives for managing weeds in alfalfa within changing pesticide regulations.

Processing tomatoes are important to the California agricultural economy; the state produced over 90% of the 12 million tons of tomatoes grown in...

Common chickweed (Stellaria media) (Figure 1) is a winter annual found throughout California and considered to be one of the most common broadleaf weeds infesting cereal crops (also referred as small grains) in the state (Wilen 2006). Herbicides can provide effective control of chickweed; however, overreliance on a single herbicide (or group of herbicides with the same site of action), is likely to result in resistance to that herbicide (or group of herbicides) (Tranel and Wright 2017). Even though herbicide-resistant common chickweed populations have not been confirmed in California, lack of effective control with post-emergence applications of the ALS-inhibiting herbicides pyroxsulam (Simplicity) and tribenuron (Express...
