Synopsis

Fusarium oxysporum, Phytophtora infestans and Alternaria alternata  are a soil borne fungal pathogen that attacks plants through roots at all stages of plant growth, causes major economic losses by inducing necrosis and wilting symptoms. Trichoderma sp. tested against the selected fungi under in vitro conditions. The results revealed that Trichoderma sp. showed maximum inhibition against the three pathogenic fungi Alternaria alternata strain (A), Fusarium oxysporum strain (F) and Phytophtora infestans (P). It may be therefore a promising ecofriendly bio controlling sources and cost effective for the safe agricultural practices as well as to farmers.
