COMPARATIVE EFFICACY OF ORGANOPHOSPHATES, ORGANOCHLORINES, PYRETHROIDS AND BIOPESTICIDES IN LONG-TERM PROTECTION OF PEA POD BORER, Lampides boeticus (LINN.) UNDER NATURAL CONDITION

摘要

An experiment was conducted to study the efficacy of organophosphates, organochlorines, pyrethroids and biopesticides in long-term protection of Pea pod borer, Lampides boeticus (Linn.) in the experimental field of Department of Life Sciences, ManipurUniversity. Among the treatments evaluated against the pod borer, L. boeticus on pea crop, Monocrotophos (0.05%) afforded highest reduction (88.63% in 2000 and 93.72% in 2001) in both the years. Endosulfan (0.05%) was also observed at par in reducing the pod damage percent with Monocrotophos (0.05%). From rest of the treatments, Biopesticides such as Bioneem registered effective treatment with the reduction percent of 78.99 in 2000 and 89.26 in 2001.
