Abstract

during the period October to May 2019. Study was under taken to determine the efficacy of selected insecticides, fungicides and their combinations against major pests and disease of cashew. Among the tested chemical molecules and combinations tested, lamda-cyhalotrin in combination with copper oxychloride recorded lower incidence of die back (17.23 %) with highest per cent reduction over the control (71.89%) and produced highest yield (26.21 kg) followed by quinolphos in combination with Mancozeb (20.58%, 66.42% and 23.50 kg) and hexaconozole (22.42%, 63.43% and 22.41 kg, respectively.) compared to untreated control. No phytotoxicity symptoms were observed in treated field. So the tested combinations are compatible each other and could be safely used for the control of simultaneous occurrence of tea mosquito bug and dieback disease of the cashew.
