A comparison was made of several soil insecticide-rate combinations with the 0.75 Ib rate of Bux l0® (m- (l-ethylpropyl) phenyl methylcarbamate mixture (1-4) with m- (I-methylbutyl) phenyl methylcarbamate) for control of larvae of Diabrotica virgifera LeConte. Baygon® (o-isopropoxyphenyl methylcarbamate) at 0.75 and 1.0; Dasanit® (O,O-diethyl O-[p- (methylsulfinyl) phenyl] phosphorothioate) at 0.75 and 1.0; Dyfonate[ (O-ethyl S-phenyl ethylpliosphonodithioate) at 0.25, 0.50, 0.75, and 1.0; Furadan[ (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) at 0.25, 0.50, 0.75, and 1.0; Dursban[ (0,0- diethyl 0-3,5,6-trichloro-2,-pyridyl phosphorothioate) at 0.75; Landrin[ (3,4,5-trimethylphenyl methylcarbamate) at 1.0; and phorate at 1.0 1b actual toxicant per acre gave control comparable to the Bux 10 standard. Although these rates were not significantly different from the Bux 10 standard, it was concluded that under environmental conditions similar to 1967, Bux 10 at 0.75; Dasanit at 0.75 and 1.0; Dyfonate and Furadan at 0.25, 0.50, 0.75, and 1.0; and Landrin and phorate at 1.0 1b actual toxicant per acre would be expected to perform comparable to Dyfonate at 1.0 1b actual toxicant/acre, the best treatment in this study. Evaluation under differing environmental situations is required before a definite application rate can be determined.
