Abstract

A study was conducted to determine the median lethal concentration of neem for common carp (Cyprinus carpio) as a non-target organism. Five test concentrations and a control were used in triplicates to determine the 72 hour MLC of neem gold pesticide. With the increase of dose concentration (0.05, 0.07, 0.09, 0.12 and 0.17 ml/L-1) and exposure duration significant increase in the mortality level was noticed. The 72 h LC50 values (with 95% confidence limits) of Neem Gold for common carp juvenile were found to be 0.09799 ml/L-1.
