Fall Armyworm Control on Peanuts, 1984

Seven insecticides were evaluated for fall armyworm (FAW) control on peanuts near Palmyra in northern NC. Seed were planted in early May into Norfolk fine sandy loam soil on 36-inch rows. Plots were 4 rows by 40 ft arranged in a randomized complete block design with 3 replications. A backpack sprayer calibrated to deliver 8 gal H2O acre at 50 psi and 4 mph with one TX-8 nozzle per row was used for the low volume treatments; 3 TX-6 nozzles per row delivering a total 18 gal/acre were employed for the high volume treatments over each row. A pretreatment FAW count yielded 12 larvae/row ft. Treatments were made on 30 Aug. Live FAW larvae were sampled from 3 row ft from each plot on 4 Sep.
