Sharanabasappa, Pavithra HB, Maruthi MS and Nagarajappa Adiveppar

A field experiment was conducted on the efficacy of different insecticides against mango leafhoppers during 2014-2015 and 2015-2016 at Doddabbigere of Chennagiri Tq of Davavagere District. The results revealed that among the different insecticidal treatments, dinotefuron 20 SG found to be best the treatment which recorded a significantly lowest number of nymphs and adults, followed by imidacloprid 70 WG and acetamaprid 20 SP found to be more effective against leafhoppers. The next best treatments were, buprofezin 25 SC, thiamethoxam 25 WG, and imdidacloprid 17.8 SL. The plots treated with dinotefuron 20 SG registered the highest (97.50 q/ha) yield which was followed by imidacloprid 70 WG (89.38 q/ha). The treatments of acetamaprid 20 SP, buprofezin 25 SC and thiamethoxam 25 WG produced a satisfactory yield of 85.32 q/ha 86.25 q/ha and 83.50 q/ha respectively. Economics of different treatments showed that Incremental CB ratio were obtained in case of dinotefuron 20 SG (1:4.15), imidacloprid 70 WG (1: 3.93), Acetamiprid 20 SP (1:3.84).
