Declare War On Armyworms

armywormsTwo 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 armyworm and fall armyworm 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 the fall armyworm beginning in July.

At Walden Farm & Ranch Supply, we’ve got solutions for armyworm control, including pasture spraying services and do-it-yourself products for your lawn and pasture.  There are several different pesticides that can be used to control armyworms in pastures and hayfields and we’ve got them in-stock. Stop by one of our area Walden FRS locations and together, we’ll come up with a plan to win the war on armyworms. Read more about armyworm control here.
