Abstract
A mixture of toxaphene plus DDT and Guthion® (0,0-dimethyl S-(4-oxo-1,2,3-benzotriazin-3-(4H)-ylmethyl) phosphorodithioate) or methyl parathion gave much better control of the boll weevil (Anthonemus grandis Boh.) and the cotton fleahopper (Psallus seriatus (Reut.)) than dieldrin or toxaphene. Toxaphene was more effective than Strobane® (mixture of chlorinated terpenes with about 66% of cholorine) against thrips (Frankliniella sp.), but both materials gave poor control of cotton fleahoppers and boll weevils. In mixtures with DDT the materials were equally effective against these pests. Sevin® (1-naphthyl methylcarbamate) in a wettable-powder formulation was effective against thrips, cotton fleahoppers, and boll weevils, but rains occurring a short time after application reduced its effectiveness. Shell SD 4402 (1,2,3,4,5,6,7,8,8-octachloro-3a, 4,7,7a-tetrahydro-4,7-methanophthanlan), Shell SD 3562 (dimethyl 1-(dimethylcarbamoyl)-1-propen-2-yl phosphate), Bayer 25141 (O,O-diethyl O-(p- methylsulfinyl) phenyl phosporothioate), and dimethoate were as effective as dieldrin in thrips control.
