Abstract:
Fall armyworm (FAW) is an important and destructive pest causing heavy damage to maize crops throughout India and abroad. Considering the importance of FAW, an experiment was conducted to evaluate various modules against Spodoptera frugiperda infesting maize. Modules viz., Bio-intensive module, chemical intensive module and Integrated Pest Management (IPM) Module were framed and the its evaluation was carried out under field conditions for two years during kharif, 2021 and 2022. The IPM module consisted of border crop of sunflower; seed treatment with cyantraniliprole 19.8% + thiamethoxam 19.8% FS, 2.38 g a.i./kg seeds (6 ml/kg seeds); collection and destruction of egg masses and neonate larvae during initial crop stages; spraying of Bacillus thuringiensis 1% WG, 20 g/10 litres of water at 30 DAS; whorl application of soil, 5 g/plant at 45 DAS; and spraying of chlorantraniliprole 18.5 SC (3 ml/10 litres of water) at 60 DAS. Of the evaluated modules significantly the least larval population (0.44 larva/10 plants), plant (5.14%) as well as cob damage (17.77%) and highest grain (2945 kg/ha) as well as dry fodder yield (4132 kg/ha) and ICBR (1:2.37) was recorded in the Integrated Pest Management (IPM) module. It was followed by the chemical intensive module with mediocre and bio-intensive module with lesser effectiveness against fall armyworm infesting maize.
