ABSTRACT

 

Earthworms are beneficial to agriculture. Pesticides are widely used in agriculture for pest management. However, due to injudicious and indiscriminate use of pesticides beneficial flora and fauna has been influenced. Hence the present investigations were carried out to study the influence of lindane and endosulfan on the population of earthworm. Ten earthworm cocoons were released in container containing unfortified and fortified soil at 0, 5, 10 and 20 ppm level of lindane 20 EC and endosulfan 35 EC. Treatments were replicated thrice. Population count in untreated soil ranged between 99.6 to 104.3 as against 94.4 to 102.0 at fortification level of 5 to 20 ppm of the pesticides. Negligible variation was registered between fortified and unfortified soil which did not indicate the adverse effect on the population of the earthworm upto 20 ppm fortification level of the lindane and endosulfan in the soil. Based on present investigations, it could be concluded that 5 ppm level of fortification of these pesticides could be considered comparatively safe to the earthworms in the soil.
