Corn Borer: June - August
Corn Borer is a non-native species and has been a substantial pest to the Midwest since the 1920s.
Like other pests, Corn Borer can have multiple generations within a growing season. The first generation will bore into whorls of leaves and then move down the stalk as they age,
Management of Corn Borers can be economically taxing but might be necessary if severe. Other ways to avoid Corn Borer damage include planting hybrids with genetically introduced Corn Borer toxins.
