Insecticide usage patterns adopted by paddy growers to manage N. lugens were collected through roving surveys using a questionnaire during 2020-21 and 2021-22 Kharif season from the major paddy growing areas of Karnataka. It is evident from the survey that overall, 15 insecticides and one combination product belonging to various chemical groups with different mode of action have been sprayed in Karnataka to manage N. lugens (BPH). In which neonicotinoids and organophosphates comprise major share with 29 and 22 percent, respectively, followed by pyridine azomethines (Pymetrozine 50% WG) with 19 percent and novel mesoionic class with 10 percent. Overall, the survey found that farmers in the TBP and UKP areas were using several insecticides with repeated applications to manage N. lugens, followed by the Borewell irrigated area and the Cauvery command area. Whereas, rarely spray any insecticide for paddy pest management in hilly and coastal regions.
