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:
