Chemical and biological insecticides were evaluated for control of Heliothis zea (Boddie) on sweet corn during 2 years in central and south Florida. CIBA C-9491 (O-(2, 5-dichloro-4-iollophenyl) O,O-dimethyl phosphorothioate), diazinon, Dursban® (O,O-diethyl O-(3,5,6-trichloro-2- pyridyl) phosphorothioate), Fundal® (N-(4-chloro-o-tolyl) -.N,N-dimethylformamidine hydrochloride, Gardona® (2-chloro-I-(2.4.5-trichlorophenyl)\vinyl dimethyl phosphate), methomyl, Monitor® (O,S-dimethyl phosphoroamidothioate), parathion + methyl parathion, parathion + toxaphene, Phosvel® (O-(4-bromo-2,5-dichlorophenyl) O-methyl phenylphosphonothioate), and Union Carbide UC-34096 (4- [[ (dimethylamino)methylene]amino] -m- tolyl methylcarbamate hydrochloride) gave 95% or higher control when applied approximately daily, whereas certain other chemicals and the HD-l Brownsville strain of Bacillus thyuringiensis Berliner were inadequate. Insecticides applied at less frequent intervals did not give adequate control.
