  • Abstract

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.
