Armyworm Update Week of September 1st - Last update
The number of moths caught in the traps continue to go down. At this point, rice is maturing and the stage when it is susceptible to armyworm panicle injury is past. There are still a few worms in the field, but these are the last of the population and will not cause problems. I expect the numbers will continue to go down.
This is the last armyowrm email update for this season. We will continue to check traps for two more weeks to have the complete picture the armyworm dynamics for the season. I want to thank all the growers and PCAs that let us put traps in their fields and gave us updates on the armyworm, the California Rice Commission for helping disseminate the information, and Corteva (formerly Dow AgroSciences) and the Rice Research Board for funding. We plan on removing the traps on September 15, but if you need the traps removed before then, just let me know.
