Biointensive management of brinjal shoot and fruit borer, Leucinodes orbonalis Guen.: Technology demonstration and impact

Abstract

Studies were conducted to assess the impact of the biointensive management (BIM) module through field demonstrations to manage brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guen. In Tumkuru district of Karnataka. Results revealed that mean shoot infestation was 6.52% in demonstrated field compared to 29.32% check plot. Initially, the relative level of fruit damage between treated and untreated plot was not prominent. However, in later harvests the treatment effect became more evident. The average fruit infestation of 11.27% was recorded in BIM implemented plot, whereas check plot recorded the highest fruit infestation (31.07%) corresponding to higher yield (280.51q/ha) than control plot (208.02 q/ha). Management of BSFB through this technology resulted in a benefit cost ratio of 2.48 to farmers.
