| Summary: | The ovicidal property of four fertilizers such as urea, ammonium
sulphate, quick lime and ash at 1, 2.5 and 5 per cent strengths was studies both in faecal culture as well as in egg culture. In faecal culture, urea and ammonium sulphate had 100 per cent ovicidal property even at the minimum strength of 1 per cent. Quick lime had 36.52, 58.60 and 78.38 per cent ovicidal property at 1, 2.5 and 5 per cent strengths respectively. Ash showed the least efficacy of 5.62, 21.3 8 and 52.40 per cent respectively at the above strengths. In egg cultures quick lime showed highest ovicidal property (100%) even at 1 per cent strength. But urea and ammonium sulphate did not show any ovicidal property at 1 and 2.5 per cent but at 5 per cent both had ovicidal effect. But the fate of eggs directly treated with ash could not be assessed as the eggs were not clearly visible because of turbid nature of solution |
