Abstract

Parathion was the most effective ovicide for European corn borer eggs. Six other materials gave at least 50% mortality at 100 p.p.m., but 17 had little or no activity. Corn borer larvae were more susceptible to insecticides, and probit-mortality data was determined for 17 materials.

In 1970 and 1971 heavy populations of borer were controlled on sweet corn and peppers by twice-weekly sprays of carbaryl, Lannate, and Phosvel. Furadan applied weekly provided good control, and several of the experimental compounds were effective.
