Validation of integrated pest management tools against Lepidopterous insect pest of rice

Studies on IPM module and its comparison with farmer’s practices revealed that the incidence of Scirpophaga incertulas recorded from 15 to 113 DAT varied widely ranging from 1.17 to 5.32% in IPM module whereas, in farmer’s practices the incidence varied from 5.15 to 6.95 during kharif, 2018. Incase of the incidence of leaf damage by Cnaphalocrocis medinalis from 15 to 113 DAT ranged from 2.94 to 7.72% incidence of leaf damage as compared to 6.61 to 9.86% leaf damage in farmers practices. Similarly, it was evident that the incidence of stem borer recorded at 15 DAT up to 113 DAT varied widely ranging from 0.98 to 6.12% in IPM module whereas, in farmers practices the incidence varied from 6.51 to 10.19 during kharif, 2019. The data on effect of IPM technologies as against farmer’s practices presented shows that the incidence of leaf damage recorded from 15 to 113 DAT ranged from 2.46 to 6.26% incidence of leaf damage as compared to 6.94 to 9.83% leaf damage in farmers practices.
