Four field tests were made with 1st- and 2 with 2nd-generation Ostrinia nubilalis (Hubner) on field corn during 1966 and 1967 to compare the control obtained with 27 chemicals applied at various rates and in several formulations. Chemicals producing control equal to that obtained with 1 lb DDT per acre (pounds active ingredient per acre in parentheses) were: phorate (1), diazinon (1), Dursban® (O,O-diethyl 0-3,5,6-trichloro-2-pyridyl phosphorothioate) (0.25), Furadan® (Niagara NIA-10242) (2,3-dihydro-2-2-dimethyl-7-benzofuranyl methylcarbamate) (0.25), EPN (O-ethyl O-p-nitrophenyl phenylphosphonothioate) (0.25), Azodrin® (3-hydroxy-N-methyl-cis-crotonamide dimethyl phosphate) (0.50), Gardona® (Shell SD-8447) - (2-chloro-1- (2,4,5-trichlorophenyl) vinyl dimethyl phosphate) (0.75), Hercules 14503 (O,O-diethyl phosphorodithioate S-ester with N- (2-chkoro-1-mercaptoethyl) - phthalimide) (1.25), American Cyanamid CL-47470 (cyclic propylene (diethoxyphosphinyl) dithioimidocarbonate) (1), Stauffer N-2790 (O-ethyl S-phenyl ethylphosphonodithioate) (0.75), parathion (0.5), a mixture of parathion + endrin (0.5 + 0.1) , and a mixture of parathion + heptachlor (0.5 + 0.5) .
