Field bioefficacy of flufenzin and fenpyroximate on red spider mite, Tetranychus cinnabarinus (Boisd) infesting brinjal*

Field-bioefficacy of flufenzin, fenpyroximate and dicofol @ 60,80,&100, 15,20,&25 and 250 g a.i./ha, respectively was evaluated against red spider mite (Tetranychus cinnabarinus) on brinjal. Fenpyroximate was more effective than flufenzin in protecting the crop against the mite. Relationship of profit margins-contributed by the acaricides suggested that all the three dosages of fenpyroximate and the higher dosage of flufenzin effectively controlled the mite and extended better monetary returns. None of the acaricides exhibited any phytotoxicity.
