Abstract:Control of the two-spotted spider mite (Tetranychus telarius (L)) on lima beans in southern California was obtained for 2 to 3 months by applying granulated or liquid insecticides in the seed furrow at planting time. Seed coatings were also effective. Phorate (formerly Thimet® (O, O-diethyl S-(ethylthio)methyl phosphorodithioate)) and Di-Syston® (O, O-diethyl S-2-(ethylthio) ethyl phosphorodithioate) were used most extensively, but some of the other insecticides showed promise. Dosages of less than 1 pound per acre were as effective as higher dosages and showed no appreciable phytotoxicity. Crop yields were increased and little or no residue was found in the dry beans. Higher dosages resulted in reduced plant stands. For the control of thrips (Frankliniella moultoni Perg.), phorate was better than Di- Syston, but 2 to 4 pounds per acre were required.
