At some point each year I give up keeping track of counties and declare a statewide fall armyworm epidemic. Today is the day! Fall armyworms in pastures or hayfields have now been reported in 49 counties, as of August 13, 2014: Autauga, Baldwin, Barbour, Blount, Butler, Calhoun, Chambers, Cherokee, Chilton, Choctaw, Clarke, Covington, Crenshaw, Cullman, Dale, Dallas, Dekalb, Elmore, Etowah, Fayette, Geneva, Greene, Hale, Henry, Jackson, Lamar, Lauderdale, Lawrence, Lee, Limestone, Lowndes, Macon, Madison, Marengo, Marshall, Montgomery, Morgan, Pickens, Pike, Randolph, Russell, St. Clair, Sumter, Talladega, Tallapoosa, Tuscaloosa, Walker, Wilcox, Winston, and Washington. The fall armyworm watch map has been updated.
If you find fall armyworms in other counties in Alabama I will be happy to update the map. But the main thiing is to keep checking your grass forages for fall armyworn until first frost. I expect more armyworm problems will be discovered next week, as another generation matures. But already, we have a situation where the generations are overlapping. Now is the time to consider using insecticides with a longer residual to provide protection against larvae that hatch after the insecticide has been applied.
