Abstract

                                Different animal excrements were assayed for fungitoxicity against Fusarium oxysporum f.sp. lycopersici, the causal agent of tomato wilt. Among them, cold and hot water extract of buffalo urine at 10 per cent concentration recorded complete inhibition of the mycelial growth. Physical properties like autoclaving at temperature 90°C for 10 minutes did not alter the toxicity. Toxin and hydrolytic enzyme production was also inhibited by buffalo urine. Seed treatment with buffalo urine enhanced the seed germination, growth and vigour of tomato seedlings.

Key words : Buffalo urine, Fungicidal activity, Fusarium oxysporum f.sp. Lycopersiciq
