Armyworm Monitoring

2019 Armyworm Trapping

Update August 21

True armyworm moth numbers remains low, except for the location near Knights Landing. This site tends to have higher moth numbers, most likely due to the diveristy of crops around it. However, armyworm damage in this site has always been low. 

Other sites I have visited had very few medium size worms, and damage to the panicles was very low. The traps seem to indicate that in most locations we won't have a high peak, and that worm infestation should not be a problem. Keep scouting in late planted fields, especially in areas of more crop diversity.

Thanks to Corteva Agriscience for helping fund the 2019 armyworm trapping network.

I'm using the FarmDog app to keep track of sampling sites and moth counts.
