 ABSTRACT

Field trail was conducted on farmer’s field at two different locations in the Dangs during 2017-18 to evaluate the bio- efficacy of six  different treatment comprised of insecticide molecules and azadirachtin 10000 ppm against tea mosquito bug in cashew. The results revealed that, among the different treatment tested significantly highest 62.60 per cent mortality of tea mosquito bug was observed in treatment T6 (buprofezin, azadirachtin, buprofezin). The next effective treatments were T4 (diafenthiuron, azadirachtin, diafenthiuron) and T5 (pymetrozine, azadirachtin, pymetrozine) which remained at par and proved equally effective as they registered 54.24 and 52.69 per cent mortality of tea mosquito bug. The highest nut yield (1027 kg/ha) and cost benefit ratio (1:7.13) was recorded in treatment T6 (buprofezin, azadirachtin, buprofezin).
