The mean number of leaves damaged, the leaf area damaged and mean number of plants infested in the treatments of emamectin benzoate and chlorfenapyr were on at par with each other and significantly less than all other treatments followed by metaflumizone. These treatments also recorded higer yield parameters in terms of cured leaf, bright leaf and grade index.
