BIOEFFICACY OF NEONICOTINOID INSECTICIDES AGAINST THRIPS PEST (Thrips palmi) ON GRAPE VINE (Vitis vinifera L.) |  UTTAR PRADESH JOURNAL OF ZOOLOGY

The grape thrips (Thrips palmi) is a major pest that causes significant losses in commercial grape production (Vitis vinifera L.). In West Bengal, India, it has become a significant pest of grape vine. The efficacy of neonicotinoid insecticides spinetoram 10% w/w + sulfoxaflor 30% w/w WG @ 100, 120, and 140 a.i. g /ha, 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% SG and bu Spinetoram 10% w/w + sulfoxaflor 30% w/w WG @ 140 g a.i./ha was the most effective against thrips on grapes, and it was on par with spinetoram 10% + sulfoxaflor 30% WG @ 120 g a.i./ha. The same tendencies can be seen in yield. The pesticides tested were also found to be less toxic to predators such as Menochilus sp., Syrphus sp., and Chrysoperla sp.

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.
