Abstract

This publication describes a technique used to evaluate the relative performance of insecticides in protecting corn roots from feeding damage by corn rootworm larvae.

Insecticides applied at planting or cultivation time are commonly used in continuous corn to protect the roots from damage by western and northern corn rootworms.

Measuring the relative performance of these insecticides in protecting corn roots from rootworm larval damage is important.
