Armyworm Monitoring

End of 2021 Season

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 grower and PCAs that participated in the network this year and Corteva Agriscience for funding.
 
Happy harvest!

End of season
