Nemagon, widely applied to the soil to control a number of plant parasitic nematodes, was tested for its efficacy against development stages of Haemonchus contoruts, a sheep bookworm, from egg to infective larvae, in soils of varying physicochemical compositions. Maximum efficacy of Nemagon was observed in red soil of Kanke (Bihar) followed by those of Imphal, Lucknow, Aligarh and Black cotton soil of Kota (Rajasthan) in decreasing order. The recovery rate of nemagon from different soils corresponded with its bioactivity. The differential efficacy of Nemagon in soils was possibly due to varying. degree of adsorption by clay minerals was organic matter present in different soils. Concentrations in which Nemagon is generally applied to soils (0.8 to 1.0 ton/hectare) for plant pest control is sufficient to prevent the transformation of 5% of Haemonchus eggs to infective larvae.
