Field evaluation of biological compatibility of selected agrochemicals against cotton leafhopper, Amrasca biguttula biguttula (Ishida)

Author(s): Bontha Rajasekar and CP Mallapur
Abstract:
A field trial was conducted to evaluate the bioefficacy of combinations of insecticides with fungicides / fertilizer / growth regulator, as foliar application on Bt cotton against cotton leafhopper. The lowest population of leafhopper was recorded in diafenthiuron 50 WP @ 0.6 g + carbendazim 50 WP @ 1.0 g (2.87 / 3 leaves) followed by diafenthiuron 50 WP @ 0.6 g alone (2.99 / 3 leaves) with 74.30, 73.21 high per cent reduction over control. Sequentially in the efficacy, treatments i.e., spinetoram 12 SC followed by acetamiprid 20 SP, nimbecidine, thiamethoxam 25 WG were alone and its combinations found effective in reducing the leafhopper population in 60 days cotton old crop.
