Johnsongrass in organics: Mow it?
Yes, mow it! Mowing works to at least prevent seed spread and regular mowing will weaken rhizomes.
Seed establishment has the greatest potential for the establishment and spread of johnsongrass and must be prevented. Therefore, mowing works to at least prevent seed spread. An individual plant can produce 28,000-30,000 seeds and a single inflorescence can measure 1,240 seeds...

Impatiens Necrotic Spot Virus (INSV) in the Salinas Valley is a tospovirus that is spread primarily by western flower thrips (Frankliniella occidentalis). It has a wide host range of over 600 species of plants, including vegetables such as lettuce, tomatoes and peppers, ornamental such as fuchsias, dahlias and gazanias, and many weeds (see below). In the summer months when INSV is well established, lettuce production fields serve as the primary host of the virus, and thrips fly from infected fields that are being harvested to younger unharvested fields, and in that way, propagate and spread...

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...
