An experiment was conducted to evaluate some acaricides against chilli mite, Polyphagotarsonemus latus Banks under field condition. Acaricides viz. clofentezine, flufenzine, dicofol and sulfur were applied at recommended doses as a sole application and tank mix formulation of clofentezine and dicofol. The maximum reduction of eggs hatchability (53.03%) was recorded in clofentezine treated plots followed by dicofol (36.02%), flufenzine (27.37%) and sulfur (26.03%). The highest reduction of motile stage was observed in sulfur (78.35%) treated plots followed by dicofol (75.88%), flufenzine (42.08%) and clofentezine (25.65%). Tank mix formulation of clofentezine and dicofol at both low and high doses recorded higher mortality (87.80 and 97.66%) of mite as compared to sole application of individual acaricide, respectively. Yield of chilli was also higher in both doses of tank mix formulation treated plots (25.80 and 26.10 q ha-1), respectively.
