On-farm tests were conducted in Craven, Wayne, Hertford, Martin, and Sampson counties to determine the potential for aphid control from insecticides applied prior to transplanting flue-cured tobacco. Plots consisted of 4 rows x 78 ft separated by vacant 5th middles and 10 ft alleys between each of 4 replications at Craven and Wayne counties and 2 replications at other sites. Some insecticides were disced into the soil prior to ridging of rows while others were added with the transplanter water. Live aphids were counted on the 2 heaviest infested leaves of 10 randomly selected plants of each plot 2, 3, and 4 weeks post-transplant. Data were subjected to analysis of variance and orthogonal partitioning of treatments.
