Development of bipm module against brinjal shoot and fruit borer leucinodes orbonalis guenee for northeast india

The effectiveness of biointensive IPM (BIPM) against brinjal shoot and fruit borer (BSFB) was investigated in comparison with highly chemical dependent farmers’ practice with pesticides and untreated check. The BSFB caused 9.27, 12.25 and 17.30% shoot damage, and 17.02, 19.86 and 29.05% fruit damage with BIPM, farmers’ practice and untreated check, respectively. Although, the yield of the BIPM module (233.64 q/ha) was slightly lesser than farmers’ practice (234.40 q/ha), both were significantly differing in terms of yield. The cost: benefit ratio of BIPM module (1:3.85) was more than that of farmers’ practice (1:3.33) due to higher cost of pesticide than biocontrol agents.
