Whitney Brim-Deforest and Sarah Marsh sit down to talk about herbicide resistance in California rice. Herbicide resistance is continually quoted as a primary concern among rice producers and researchers. Due to a myriad of reasons, there are very few chemistries available for weed control in CA rice; among these, herbicide resistance has been reported in all but the most recent.

• Annual Rice Field Day on August 28
• Rice Pest Management Course on September 4 *registration required*

Today Whitney Brim-Deforest and I will be sitting down to talk about weedy rice in California. Weedy rice is the same species as cultivated rice, Oryza sativa, which contributes to the difficulty in controlling it; any herbicide that would kill weedy rice would also hurt the crop. Weedy traits of weedy rice including seed shattering and long dormancy. What that means is that the seeds fall off the panicle really easily and can remain dormant in the soil seedbank for years before germinating.

Today Luis Espino and I will be talking about Rice Armyworm Monitoring Program and the second generation of armyworms in rice.

Two true armyworm generations occur in rice; moths fly in spring and early summer, laying eggs in rice fields and surrounding vegetation. The larvae that emerge feed on rice foliage. A second moth flight occurs in mid-summer, followed by larvae feeding on rice foliage and panicles.
