Updates from University of California on a new Herbicide and Armyworm

The steady flow of information from UC Cooperative Extension (UCCE) rice experts continues with two new posts. 

From UCCE Rice Advisor Whitney Brim-DeForest is this post from today of a new rice herbicide available this year for use: RebelEX®, manufactured by Corteva.

From Rice Farming Systems Advisor Luis Espino is this week’s armyworm monitoring update:

On average, we are getting 30 moths/day in the traps. This is as high as the average peak we saw in 2018 and 2019. However, the number of larvae in the fields we are monitoring remains very low. Injury to the foliage is minimal.

As fields go into heading, and moth populations start increasing, risk of panicle injury will also increase.
