The soil type was Plainfield Loamy Sand, pH 6.2. The moisture on this crop was 16 inches of rainfall and overhead irrigation. The 2 center rows of each plot were sprayed on July 9, 16, 23, 30, August 6, and 13 using tractor mounted Myers sprayer with a 6 ft boom delivering 33 gal of spray per acre. European corn borer egg masses at 2 egg masses per plant were pinned on one sprayed row of plants in each plot on July 29. European corn borer damage readings and yields were taken on August 18.
