Cutworms

cutworms, the larvae of several species of moths, are one of the most serious pests of all sorts of crops worldwide. They hide in the soil or under the vine’s bark during the day and emerge to feed and cause damage at night. Young vines are particularly prone to damage. When cultural practices, natural enemies, and climatic factors do not keep cutworms to tolerable levels, there are highly effective chemical agents which can prevent major losses. DDT was once used, but there are now effective contact insecticides.
