Abstract

Fall army worm Spodoptera frugiperda (J E Smith) is a significant invasive pest in maize, feeding from young seedlings till maturity. Field experiments were conducted to assess the effectiveness of new insecticides in maize during 2024 and 2025. The lowest incidence was observed in Spinosad 2.5%SC (9.87 and 13.18%); it was followed by plots treated with Bacillus thuringiensis and Metarhizium anisopliae. Application of cartap hydrochloride 50SP @ 2 ml/ l and Novaluron 10EC@ 2 ml/ l also recorded less larval incidence as compared to control. Among the treated plots, diflubenzuron 2%G @2 ml/ l recorded the highest incidence.
