Abstract

A field experiment was conducted in a randomized block design to find out the effective management of fall armyworm, Spodoptera frugiperda (J S Smith) in maize (Zea mays L.) through different insecticides and bio-pesticides during kharif 2019 and 2020 at Agronomy farm, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur, Rajasthan. The three sprays of chlorantraniliprole 18.5 SC were found most effective treatment against S. frugiperda and gave the better results with maximum reduction of larval population, lowest plant damage (%), lowest leaf damage (%), lowest cob damage (%) and highest grain yield. It is followed by emamectin benzoate 5 SG and found at par at 5th day after each spray. The next effective treatments were spinosad 45 SC, thiodicarb 75 WP, Beauveria bassiana, Metarhizium anisopliae and azadirachtin 10000 ppm. The maximum Incremental Benefit Cost Ratio was obtained from the three sprays of emamectin benzoate 5 SG.
