Fall Armyworms in Turf and Pastures
By Steve Bambara and Rick Brandenburg, Extension Entomologists

Despite low numbers being reported in light traps, fall armyworm (Fig. 2) infestations have exploded this week in eastern North Carolina. In turf, some lawns are disappearing overnight. The hot weather seems to be aiding their development. Moths are blown into North Carolina from states farther south each year. Within an area, female moths are attracted by light and lay eggs on anything (usually not the crop). As the eggs hatch and the caterpillars grow, they spread out from that point eating all that they can. Infestations start along a field or lawn edge such as next buildings, or along fences and street lights.
Homeowners can use some product containing bifenthrin (or similar) or Sevin can be applied. It is best to apply in morning or evening. Follow directions for the product used. In severe cases, there may be no time for granules to be rained-in and spray would be recommended. Consider pending weather conditions.
