There were eight treatments viz., Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 375 + 37.5 g a.i./ha, Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 500 + 50 g a.i./ha, Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 625 + 62.5 g a.i./ha, Chlorpyriphos 50% EC @ 225 g a.i./ha, Chlorpyriphos 50% EC @ 600 g a.i./ha, Cypermethrin 10% EC @ 60 g a.i./ha, Deltamethrin 2.8% EC @ 12.5 g a.i./ha and untreated control tested against leaf miner infesting ground nut. The results of two sprays against leaf miner infesting ground nut revealed that the lowest leaf miner damage was recorded by the treatments Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 625 + 62.5 g a.i./ha, Chlorpyriphos 50% EC @ 600 g a.i./ha, Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 500 + 50 g a.i./ha and Deltamethrin 2.8 EC @ 12.5 g a.i./ha after two sprays during 2019. Whereas, in year 2020 the leaf miner damage was lowest in the treatment Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 625 + 62.5 g a.i./ha, Chlorpyriphos 50% EC @ 600 g a.i./ha, Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 500 + 50 g a.i./ha, Deltamethrin 2.8% EC @ 12.5g a.i./ha and Chlorpyriphos 20% EC @ 225 g a.i./ha after second spay.

Results on yield basis proved that the treatment Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 625 + 62.5 g a.i./ha recorded maximum yield 2175 Kg per ha and 2205 Kg/ha during both the years.
