The Fall Armyworm definitely lives up to its name— Given their immense appetite, great numbers, and marching ability, armyworms can damage entire fields or pastures in a few days. Armyworms are on the march due to recent rains and lower temps— come see us at J&N Feed and Seed for the right insecticide solutions for your pasture crops.
Two species of armyworms can be significant pests of Texas forage and pasture production. The “true” armyworm is more of a spring pest of cool-season grasses and tall fescue. The fall armyworm is a summer/fall pest primarily of Bermuda grass, but it can also damage fall-seeded, newly established winter annuals, fescue, and orchard grass.
Damage from true armyworms and fall armyworms can seem to appear overnight. Although the damage might appear overnight, larvae have likely been feeding for a week or more before they or their damage appears. Large armyworms may move into an uninfested field (or area of field) adjacent to a field that was just defoliated. Because armyworms are so destructive and compete with livestock for forage, producers should diligently scout susceptible fields for the true armyworm beginning in April and for fall armyworms beginning in July.
