Abstract: Field bio-effectiveness of pre-mix formulation of cartap hydrochloride 50% SP + buprofezin 10% EC (KCB-2010) were evaluated against jassid (Amrasca biguttula biguttula), whitefly (Bemisia tabaci) and fruit borer (Earias vittella) during 2011 and 2012 in spring-summer crop. KCB-2010 @ 600 and 750 ml ha^-1 reduced okra fruit borer population to the tune of 73.07 % and 75.51 % in two seasons respectively. The treatments also provided significant reduction of jassid (59.33% and 60.87 %) and whitefly (69.46 % and 70.91%) population vis-à-vis highest yield (16.62 and 17.27 t ha^-1) in comparison to 6.66 t ha^-1 in untreated plots. Tested dosages were soft against natural enemies like, coccinellides, syrphids, spiders and staphylinids, with population reduction of 8.35 and 9.50%, 10.00 and 9.85%, 7.00 and 8.10% and 1.78 and 3.50%, respectively; hence can be considered as a suitable IPM compatible tool with favorable toxicological profile.
