Abstract

A study on the assessment of IPM module for the management of fall armyworm (FAW) in maize was conducted in farmer's fields in the maize growing tract of Prakasam district during 2018-19, 2019-20 and 2020-21. The mean FAW incidence of 13, 8, 6 and 4 per cent was recorded in IPM module over 32.6, 25.3, 19.3 and 14.6 per cent in farmer's practice at 15, 30, 45 and 60 days after sowing, respectively. The mean yield of IPM module was 70.68 q/ha with net returns and C:B ratio of Rs. 70048/ha and 1:2.46, respectively. Whereas, farmer's practice recorded a mean yield of 59.89 q/ha with net returns and C:B ratio of Rs. 50604/ha and 1:2.02, respectively. The increase in yield over farmer's practice was 18.01 per cent.
