Abstract
Complete elimination of spittlebug nymphs with high concns. of benzene hexachloride increased first cutting yields of red clover and alfalfa up to 55%. Some increase in carotenoid and protein content was also effected. Application of the insecticide as soon as possible after the nymphs complete hatching was found to be desirable. No increase in 2d cutting yields was observed. Treatment of large fields is commercially practical. In large scale tests, up to 44% increases in yield were obtained by the use of 2 to 3.2 oz. per acre of gamma isomer of benzene hexachloride. The higher concn. may be more practical to use since it gave more complete kill of the spittlebugs. The use of wettable powders in low pressure sprayers gave good control in areas covered but nozzle clogging made the operation impractical. The use of emulsions in low pressure sprayers resulted in good control.This publication has 3 references indexed in Scilit:
