Conventional acaricide Dicofol 18.5EC along with novel acaricides Propargite 57EC, Clofentazine 50EC, Cyflmetofen 20SC, Fenproximate 5EC, Dicofol 18.5EC and botanical Azadirachtin 0.03EC were evaluated against T. neocaledonicus on brinjal in laboratory and in field condition on brinjal crop var. Punjab Sadabahar. Fenproximate 5EC was most toxic with lowest LC50 value 7.095ppm, followed by Dicofol 18.5 EC 20.971ppm, Cyflumetofen 20SC 22.53ppm, Clofentazine 50SC 87.20ppm, Propargite 57 EC 108.62ppm and least was Azadirachtin 0.03 EC 319.35ppm. Relative toxicities of Fenproximate 5EC, Cyflumetofen 20SC, Clofentazine 50SC, Propargite57 EC, Azadirachtin 0.03 EC and Dicofol 18.5 EC was 2.955, 0.930, 0.240, 0.193, 0.065 and 1.00 respectively. The mean percent mortality of T. neocaledonicus in field condition was highest that of Clofentazine 80.36 &73.07 percent followed by 59.28 & 62.29 percent by Fenproximate, 53.83 & 57.85 percent by Cyflumetofen, 51.38 & 60.77 percent by Propargite, 50.56 & 52.3 by Dicofol and lastly 25.22 & 33.81 percent mortality by Azadirachtin in first and second spray. All the acaricides proved superior over control and gave protection to the crop upto 14 days after spray and the novel acaricides were much effective over standard acaricide Dicofol in field condition.
