Armyworm Monitoring Season concludes with Few Detections

Armyworm Monitoring Season concludes with Few Detections

This year’s armyworm monitoring has wrapped up, and the news is good. Here’s an update from Rice Farming Systems Advisor Luis Espino:

Our monitoring for 2021 has ended. Just like in July, the August moth peak was very small and very few worms were detected in the field. This year had very low numbers. On average, during peak weeks, the traps catch 25 to 30 moths each per night. This year the catches peaked at 5 moths/trap per night. In the field, worm numbers, defoliation, and panicle injury were low.

I want to thank all the growers and PCAs that participated in the network this year and Corteva Agriscience for funding.

Happy harvest!
