Evaluation trail of synthetic acaricides, botanicals and bio-pesticides were conducted against different life stages of two spotted spider mite, Tetranychus urticae Koch under poly house condition during summer season of both 2013-14 and 2014-15. Mite population was recorded after 12, 24, 36, 48, 60 and 72hrsof application. The efficacy of clofentazine 50 SC was found superior against egg, immature stage and adult female mites with reduction of 74.88 %, 74.98 % and 68.93 % respectively. In case of adult male, fenpyroximate 5 EC caused greater mortality (81.98 %) followed by cyflumetofen 20 SC (78.67 %). The efficacy of three botanicals remained very close to each other with performances observed below 50 %. Among the bio-pesticides used the P. fumosoroseus1x106 EC formulation caused greater percent reduction of egg (23.60 %), immature stages (24.47 %) and adult female mites (27.89 %) than the WP formulation, which was good in controlling adult male population (30.16%). In control plot there was comparatively less mortality.
