Yesterday, July 7, I found fall armyworms in a bermudagrass hayfield. It is early to find them in the county. They usually show up around the end of July. I recommend you check your pastures and hayfields.
Information on fall armyworms can be found in this Alabama Extension publication on Management of Fall Armyworm in Pastures and Hayfields.
UGA Extension insecticide control options can be found here.
