Laboratory Evaluation of Granular Soil Insecticides for Control of Sugarcane Beetle in Field Corn, 1981

Four granular soil insecticides labeled for control of corn rootworm were tested for effectiveness against the sugarcane beetle. Treatments consisted of the amounts of each material that would be applied to 6 inches of row at the labeled rate and at 1.5 and 2.0 times the labelled rate for corn rootworm control. Furadan at 0.5 times the labeled rate was also included. All treatments were replicated 4 times. Treatments were applied by hand to soil in 6 inch plastic pots in a manner that approximated in-furrow and 7 Inch band applications in the field. In-furrow treatments were applied across the pot at a depth of 1.5 inch and covered with soil. Band treatments were sprinkled onto the soil surface and covered with 0.25 inch of soil. Four ‘Pioneer 3147’ corn seeds were planted and the pots watered after treatment.
