SUSTAINABLE CONTROL OF LEAF HOPPER (Amrasca biguttula biguttula Ishida) ON GRAPE VINE (Vitis vinifera L.) |  UTTAR PRADESH JOURNAL OF ZOOLOGY

The leaf hopper (Amrasca biguttula biguttula Ishida.) wreaks havoc on grape vines (Vitis vinifera L.). In West Bengal, the pest is a limiting factor in the commercial production of grapes and many other crops. To compare their efficacy against leaf hopper, one dosage of spinetoram 10 percent w/w + sulfoxaflor 30 percent w/w WG @ 100, 120, and 140 a.i. g /ha, one dose of spinetoram 12 percent SC w/v (11.7 percent w/w), sulfoxaflor 24 percent w/v (21.8 percent w/w) SC, emamectin benzoate 5 The spinetoram 10% w/w + sulfoxaflor 30% w/w WG @ 140 g a.i./ha offered the best control of leaf hopper, followed by spinetoram 10% w/w + sulfoxaflor 30% w/w WG @ 120 g a.i./ha. The same tendencies have been seen in grape yield. The insecticides tested were also found to be highly safe to grape insect-pest predators such as Menochilus sp., Syrphus sp., and Chrysoperla sp.
