Armyworm Numbers trending lower

Armyworm Numbers trending lower

Here’s the latest on Armyworm trapping from UCCE Rice Farm Advisor Luis Espino: 

Except for one field, all traps are showing very low numbers. There are still a few worms out there, but I have not seen any fields with high numbers. In some of the fields that are headed I started to notice armyworm panicle injury, but at very low levels. As fields go into heading, and moth populations start increasing, risk of panicle injury will also increase.
