TAILIEUCHUNG - Insecticide usage pattern against Helicoverpa armigera (Hubner) in Karnataka State, India

An interactive survey was conducted during 2016-17 to document insecticide usage pattern adopted by the farmers of Karnataka state to manage polyphagous pest Helicoverpa armigera in different host crops growing areas. Among the different group of insecticides the most popular amongst the farmers were emamectin benzoate 5 SG ( %), rynaxypyr SC ( %) and profenophos 50 EC ( %). The dominant host crops for H. armigera different in the state were cotton, pigeonpea in Raichur and Kalaburgi, chickpea (Gadag), chilli (Haveri) and tomato (Kolar). | Insecticide usage pattern against Helicoverpa armigera Hubner in Karnataka State India 2018 7 8 875-882 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 08 2018 Journal homepage http Original Research Article https Insecticide usage Pattern against Helicoverpa armigera Hubner in Karnataka State India .

Among the different armigera Host group of insecticides the most popular amongst the farmers were emamectin benzoate Karnataka 5 SG rynaxypyr SC and profenophos 50 EC . The Article Info dominant host crops for H. armigera different in the state were cotton pigeonpea in Raichur and Kalaburgi chickpea Gadag chilli Haveri and tomato Kolar . Accepted Manually operated knapsac sprayer was commonly used in all localities except in 06 July 2018 Available Online Raichur and Kalaburgi where power operated sprayers were used. The refugia usage 10 August 2018 in Bt cotton was about 40 farmers only.

The currently noticed global and a range of vegetable crops Multani and distribution of H. armigera suggests that the Sohi 2002 CAB 2006 . pest may be most closely associated .
