Abstract

Fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) has emerged as a major constraint to the production of maize in India and is currently the major constraint in reducing the grain and fodder yield. Karnataka is the major maize growing state in India and the FAW was first noticed in May 2018 m Shivamogga district and later spread in different districts of Karnataka on maize causing between 20 per cent and 100 per cent leaf damage in different districts of Karnataka. Fall armyworm completes its biology in a period of 32 46 days and it completes 2- 3 generations on a single crop. Among the natural enemies recorded, Metarrhizium rileyi caused 80 to 90 per cent natural mortality of FAW during August and September in 2019 and 2020 in kharif sown maize crop. The native natural enemy's activity was more in kharif 2019 and 2020 as compared to kharif 2018. Use of non-chemical methods such as silica, plant growth regulators and biorationals is being explored. The different management tools for the fall armyworm management under R&D in Karnataka state are discussed.
