Potentiality of fungal and bacterial antagonists against Fusarium pallidoroseum (Cooke) Sacc. Causing wilt of coriander in vitro

Abstract

Coriander (Coriandrum sativum L.) is an important annual herbaceous crop known to infect by various fungal plant pathogens. Among them, wilt caused by Fusarium pallidoroseum (Cooke) Sacc. marks the first reported instance affecting coriander in Saurashtra region. Looking to the importance of disease, attempts were made to evaluate potentiality of seven fungal and six bacterial antagonists against F. pallidoroseum in vitro. The results revealed that Trichoderma koningii among fungal antagonists exhibited maximum mycelial growth inhibition of 62.38 per cent in vitro. While, Trichoderma hamatum remained the least effective with 20.27 per cent. Bacillus cereus on the other hand showed maximum mycelial growth inhibition of 63.92 per cent among bacterial antagonists. Whereas, Bacillus thuringiensis remained the least effective with 27.94 per cent mycelial growth inhibition of F. pallidoroseum under laboratory condition.
