Just yesterday I was out on an extension visit and came across more fall armyworm (FAW) damage. Pulled the turf back and found some small FAW. To get more information on what FAW look like, check out one of the latest blog posts about identification, cultural control, and a little bit about chemical controls for home owners.

With the amounts of sightings increasing I thought I would throw a list of chemical controls for turfgrass professionals for FAW.
FAW and all caterpillar pests are best controlled with insecticides when they are still small. When the caterpillars grow you will have to use a higher rate to achieve control.
