Abstract: Studies under field conditions were conducted on the efficacy of pesticides against mite, Tetranychus cinnabarinus (Boisduval) infesting Okra, Abelmoschus esculentus (L.) Moench at S.K.N. College of Agriculture, Jobner (Rajasthan) during kharif 2004 and 2005. The overall efficacy of pesticidal treatments at one, three, seven, ten and 15 days intervals against mite population revealed ethion (0.05%) as most effective with maximum fruit yield of 69.5 q/ha and 69.86 q/ha in 2004 and 2005, respectively; followed by monocrotophos (0.036%) with 65.25 q/ha in 2004 and 65.42 q/ha in 2005. The treatments of NSKE (5%), azadirachtin (0.00015%), datura extract (1%) proved least effective followed by calotropis extract (1%). The treatments of dicofol (0.04%), thiamethoxam (0.01%), acephate (0.05%) and imidacloprid (0.006%) existed in the middle order of effectiveness. The benefit cost ratio was highest in the treatment of ethion (1.87 and 1.84 in 2004 and 2005, respectively) and lowest in datura extract (1.09 and 1.06 in 2004 and 2005, respectively).
