Effect of chemical insecticides used for management of mulberry thrips on leaf yield of mulberry

Abstract

A field experiment was conducted during 2021, at Gandhi Krishi Vigyan Kendra, UAS Bengaluru, to know the Effect of chemical insecticides on leaf yield of Mulberry. The experiment was planned in Randomized Complete Block Design (RCBD) with 7 treatments T1: Acephate 75 SP, T2: Acetamiprid 20 SP, T3: Dimethoate 30 EC, T4: Fipronil 5 SC, T5: Imidacloprid 17.8 SC, T6: Dichlorvos 76 EC (std check) `and T7: Control (water spray). It was recorded that initially per plant leaf yield on 45th day after pruning showed highest in the treatment T6: Dichlorvos 76 EC (std check) and the least leaf yield per plant was recorded in T2: Acetamiprid 20 SP. Further mulberry leaf yield was calculated per hectare per crop was recorded highest in T6: Dichlorvos 76 EC (std check) and the least leaf yield per plant was recorded in T2: Acetamiprid 20 SP.
