Description: Full-grown cutworm larvae
are 1.5 to 2 inches long. Coloration will vary among species, but all tend
to be stout-bodied caterpillars with four sets of prolegs. They have the
tendency to curl into a ball when disturbed.
Hosts: Almost any plant can be attacked in the seedling stage.
Cotton and certain vegetables sometimes have stand reductions. Climbing
cutworms, such as the granulate cutworm, can be serious foliage feeders on
some crops such as peanuts.
Damage: Seedlings are girdled at the soil line, and stands may be
significantly reduced in some cases. Foliage and peg damage occur in
peanuts.
Life Cycle: Life cycles vary among the different species. Several
generations may occur each year, but overwintering larvae and the first
generation in the spring are the most damaging. Larvae overwinter in the
soil, especially in grassy or weedy situations.
Control: Fall and spring cultivation will help reduce populations
of overwintering larvae. Insecticides are effective if applied in a timely
manner and directed at the soil around the base of the crop plants.
Hi-Yield BT Dust - Biological insecticide that can be used up to day
