A COMPARATIVE STUDY OF ACORUS CALAMUS OIL, BIOSAL AND DELTAMETHRIN ON MORTALITY OF CALLOSOBRUCHUS ANALIS BY FILTER PAPER IMPREGNATION METHOD

Abstract

Mortality effect of three pesticides Acorus calamus (AC) essential oil and Biosal® (Neem formulation=NF) (Neem pesticides registered by APTA) and Deltamethrin (DM) was tested against Callosobruchus analis by Filter paper impregnation method (FIM) after 24 hours of treatment. The mortalities were observed after 24 hours treatment of (AC) 30%, 44%,65%, 84%, 92%, mortalities were observed after 24 hours treatment of Biosal® 34%, 53%, 60%, 72%, 89% whereas the mortalities were found after 24 hours treatment of deltamethrin 24%, 38%, 49% 76%, 81%. The LC₅₀ value of (AC) and (NF) was found to be 0.09999 µl/cm², 6.94503 µl/cm² respectively whereas LC ₅₀ value of (DM) was observed as 0.034721 µl/cm².
