Popis:	A number of chemical insecticides and some formulations of commercially produced microbial preparations containing Bacillus thuringiensis var. thuringiensis Berliner were applied as spays and/or dusts to cabbage, cauliflower, and bead lettuce for control of the cabbage looper, Trichoplusia ni (Hbn.). Only one of the chemical materials, General Chemicals 3583® (diethyl-1-(2,5-dichlorophenyl)-2-chlorovinyl phosphate) appeared to be comparable to the standards, DDT-toxaphene and parathion. However, several insecticides, including Dibrom® (1,2-dibromo-2,2-dichloroethyl dimethyl phosphate), ethion Guthion® ( O, O -dimethyl S-4-oxo-1,2,3-benzotriazin-3 (4H)-ylmethl phosphorodithioate), malathion, Perthane® (1,1-dichloro-2,2-bis ( p -ethylphenyl)ethane), Thiodan® (6,7,8,9, 10, 10-hexachloro-1,5, 5a , 6,9,9a-hexahydro-6,9-methan0-2,4,3-henzodioxathiepin 3-oxide), and Sevin® (1-naphthyl methylcarbamate) gave fair results. The microbial materials from different manufacturers varied in their effectiveness. Two gave good control of all sizes of cabbage loopers and displayed satisfactory residual activity. At the dosages used, they were as effective in quickness of kill and residual activity as the best of the chemical insecticides.
