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.
