The ovicidal property of four fertilizers such as urea, ammonium sulphate, quick lime and ash at 1%, 2.5% and 5% was studied both in faecal culture as well as in egg culture. In faecal culture, urea and ammonium sulphate had 100% ovicidal property even at the minimum strength of 1% while quick lime had 36.52, 58.60 and 78.02% ovicidal property at 1, 2.5 and 5% strengths, respectively. Ash showed the least efficacy of 5.62, 21.38 and 52.40%, respectively at the corresponding strengths. Quick lime showed highest ovicidal property of (100%) even at 1% strength in egg cultures. However, urea and ammonium sulphate did not show any ovicidal property at 1 and 2.5% but at 5%, both had ovicidal effect.
