Dealing with Fall Armyworms

There are a number of insecticides that will work well for control.  The following chart from Dr. Lisa Baxter, UGA Extension Forage Specialist outlines some specific ones:

Be sure that you are checking fields regularly for armyworm infestations.  If you need help assessing your situation, would like more information or want to learn how to scout for them, give me a call at the Burke Co. Extension Office at (706)554-2119.
