Pest Alert: Armyworm Damage Found in ND Wheat

July 12, 2016

NORTH DAKOTA: North Dakota State University (NDSU) reported armyworm damage in wheat fields.

Capture

Armyworms are a native species that overwinters in southern areas of the U.S. In the spring, the moths migrate to northern areas. These pests damage cereal grain crops by:

  • Feeding on leaf tissue from the ground up
  • Stripping off awns
  • Stripping off kernels

Large numbers of armyworm larvae can strip the plants of all leaf tissue. Grain fill, type of crop or variety, and weather conditions all influence the extent of yield loss. Syngenta recommends utilizing an insecticide to get ahead of these pests. Warrior II with Zeon Technology® insecticide delivers a combination of consistently reliable performance and long residual armyworm protection for wheat and barley. This insecticide also provides:

  • Quick knockdown and longer-lasting insect control
  • Reduced mixer loader and application exposure

In addition to utilizing insecticides, Syngenta also recommends to regularly scout fields to track the presence of armyworms. It is best to check fields in the evening or early morning, which is when larvae feed on plants. If there are five or more armyworms between 0.5 and 0.75 in. long/sq. ft., be sure to take action immediately.
