Abstract

                                Quinalphos (Ekalux EC 25) was diluted to 4.4% ( 1.1% a. i.) and sprayed norially on cotton fields affected with pests. Simultaneously, for toxicological evaluation of the product, cattle. goats and birds were placed in the field during spraying and directly exposed to the spray. The plasma cholinesterase enzyme estimation and haematological studies were conducted in these animals and birds at pre-exposure, 24 hours and 48 hours post-exposure time. Quinalphos did not produce any toxic symptoms or any toxicity indicative deviations in the plasma cholinesterase levels or haematological parameters.
