Abstract

A study was conducted in the College Research Farm, Rajendranagar for two years 2020-21 and 2021-22 to evaluate various ecofriendly practices for the management of fall armyworm in maize. Two year pooled results revealed that among the biological and biorational methods, significantly least number of damaged plants plot-1 were seen in Trichocard+Bt plots (41.09 %) and pheromone (41.24%) and highest were seen in control plots (88.83%). Trichocard+Bt treatment (8.67 plot-1) and chemical treated plots (9.83 plot-1) recorded significantly highest no. of dead larvae, while pheromone plots (1.30) and control plot (0.00 and 2.30) recorded minimum dead larvae. Yield and benefit: cost ratio was significantly higher in Trichocards+Bt treated plots (2.79 t a-1 and 2.54 resp.) among the biological treatments and this was followed by the pheromone treatment (1.11 t a-1 and 2.19 resp.). Biological pest management methods have an important role to play in integrated pest management and have to be popularized among the farming community for better conservation of the ecosystem.
