Now is the time to look for cutworm damage in corn.  Leaf feeding is evidence of the presence of young cutworms.  Larger cutworms cut plants at the soil line or tunnel into the base of the plant.

Cutworms are more likely to be found in fields that had weed growth prior to tillage this spring.  Late-planted fields often show the highest damage.  Also, don’t depend on insecticides applied at planting time for complete control of cutworms.

Act quickly when cutworms hit because damage occurs rapidly.  Apply insecticides with plenty of water and in the evening if possible.  Tillage following insecticide application is also helpful for best control of cutworms.

When deciding on the need for treatment consider the size of the worms and the area of the field infested.  Make sure the control action will be profitable.
