Evaluation of Seed Treatments in Corn and Soybeans for Control of Soil Dwelling Insects

Abstract

<p>Corn producers battle a variety of soil dwelling insect pests. Seedcorn maggots, wireworms, white grubs and several species of cutworms can attack either the seed or seedling plants and reduce the plant stand. Corn rootworm larvae feed on corn roots during midsummer and can significantly reduce the uptake of moisture and nutrients. Extensive feeding by corn rootworm larvae can reduce the roots to a point where wind causes the plants to lodge. Lodged plants slow harvest and grain yields can be reduced from both the root injury and the lodging.</p>
