Chemical Control and Damage Potential of Shoot Fly, Atherigona naqvii on Spring Sown Maize
Efficacy of seed treatment with chlorpyriphos, imidacloprid and endosulfan @ 5ml/kg seed; foliar application of chlorpyriphos 20 EC @ 250 ml/acre, imidacloprid 200 SL @ 40 ml/acre, endosulfan 35 EC @ 200 ml/acre and cypermethrin 2.8 EC @ 40 ml/acre were tested for the control of shoot fly, Atherigona naqvii Steyskal on spring sown maize along with recommended granular application of carbofuran 3G @ 5 kg/acre or phorate 10 G @ 4 kg/acre. Further, its damage potential was quantified in terms of reduced plant height and grain yield/plant under natural infestation. Seed treatment with chlorpyriphos or imidacloprid and foliar application of endosulfan proved to be effective along with recommended granular application of carbofuran and phorate in controlling shoot fly. Plant height and grain yield/plant were significantly reduced (48.5 and 61.2%, respectively) in shoot fly infested plants.
