Pest Alert: Black cutworm found in Illinois corn

May 23, 2016

ILLINOIS: Corn growers need to be on the lookout for black cutworms this spring.

In some areas, black cutworms have already been observed. According to moth traps from the University of Illinois, black cutworm damage can likely become a problem in mid-May for growers in south central Illinois. This means growers could start seeing cut plants in their area soon.

Syngenta advises that it’s important to scout fields frequently where corn is emerging. Signs of black cutworms include:

  • Leaf feeding
  • Cut plants
  • Wilted plants
  • Missing plants

One black cutworm larva can kill 4-5 plants, and with the cooler temperatures Illinois has been having, they can kill more. Black cutworms can destroy up to 10% of corn plants overnight. Utilizing an insecticide can help control black cutworm populations and help grow more corn.

Warrior II with Zeon technology® insecticide delivers the combination of consistently reliable performance, modern formulation technology, and long residual insect protection. Zeon® Technology, a patented quick-release, micro-encapsulated formulation with a powerful UV blocker, ensures fast knockdown and residual control of the most damaging insects, including black cutworm. Look at the Technical Recommendation sheet below on how an application of Warrior II with Zeon Technology can help control black cutworm.

Additionally, Syngenta offers Force® CS and Force 3G insecticides for control of corn rootworms, wireworms, cutworms, white grubs and other troublesome soil pests. Force provides consistent protection, even in heavy pressure zones, to help plants grow fully-developed roots and stronger stands, which ultimately helps improve yield and grow more corn.
