Sustainable Management of Fall Armyworm (Spodoptera frugiperda) in Maize through Integrated Approaches
Abstract
Frontline demonstrations were conducted in twenty locations in various adopted villages of Krishna district, Andhra Pradesh to evaluate the efficacy of Integrated Pest Management (IPM) practices against fall armyworm (Spodoptera frugiperda) in maize during rabi, 2022-23 and 2023-24. The pooled results of two consecutive seasons revealed that IPM treated plots comprising erection of pheromone traps, spraying of Bt formulations and need based spraying of recommended insecticides had resulted in 66.9 & 70.03 per cent reduction in plant damage and 57.8 & 62.8 per cent reduction in cob damage due to fall armyworm incidence in maize during 2022-23 and 2023-24, respectively. The yield gain was observed to be 17.05 and 9.3 per cent with BC ratio of 1.79: 1 and 1.96: 1 during 2022-23 and 2023-24, respectively.
