Beet Armyworm Infestations Return to Tennessee Fields

August 29, 2016

According to Dr. Scott Stewart, entomologist with University of Tennessee, beet armyworms are showing up in cotton and soybeans across the state. If not managed early, this pest can be devastating to yields. Since there have not been infestations of beet armyworm in the area for a few years, growers may confuse this insect with fall armyworm. For best control, it is important to differentiate the two pests.

To protect Tennessee cotton and soybean yields, Besiege® insecticide can help control beet armyworm outbreaks. Its convenient premix formula contains two active ingredients with complementary modes of action for dual protection against key insects. Other highlights include:

  • Contact, ingestion and ovicidal activity
  • Controls lepidopteran pests, including soybean looper, armyworms and corn earworm
  • Delivers longer-lasting residual than other lepidopteran materials
  • Protects against stinkbugs, grasshoppers, adult moths and beetle species
