Armyworms are the larval form of a moth that feed on lawns, wheat and improved pastures.
Sansone said armyworms derived their name by consuming most available foliage in an area and then migrating as a group in search of more foliage. Producers are concerned about how the infestation might affect this year's wheat crop. If there is not any wheat around, they are feeding on grain sorghum fields, hay fields and corn fields. Sansone said the high cost of insecticide is a large economic concern for producers. We don't know how much right now.
