| Popis: | Granulated phorate and granulated O,O -diethyl S -2-(ethyltthio) ethyl phosphorodithioate (Di-Syston®) were applied topically to large sugar beet plants. With this method of application the large leaves and flat petioles funneled most of the granules onto the plant crown. Both materials gave excellent and persistent reductions of the green peach aphid, Myzus persicae (Sulz.), the southern garden leafhopper, Empoasca solana DeL., and the spider mite, Tetranychus cinnabarinus Bvd., the three most important pests on sugar beet plants in the Imperial Valley after the seedling stage of growth. No residues of either phorate or Di-Syston were detected in the large roots, but phorate residues in the foliage were 0.07 p.p.m. 29 days after application. Of other materials evaluated, Thiodan® (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathi-cpin-3-oxide) gave excellent mortality of the green peach aphid; Sevin® (1-naphthyl methyl-carbamate) and ethion were promising when used for control of the southern garden leafhopper; and ethion, Trithion® ( S-(p -chlorophenylthiomethyl) 0,0 -diethyl phosphorodithioate), demeton, and Kclthane® (4,4'-dichloro- alpha -(trichloromethyl)-benzhydrol) were all effective in reducing populations of spider mites. |
