Bioefficacy of bioagents against Fusarium oxysporum f. sp. capsici

Abstract

Chilli (Capsicum annum L.) is associated with various diseases, which can lead to substantial yield reductions. Timely detection of causal pathogens is essential for the implementation of effective management strategies, thereby preventing epidemic development and minimizing losses. accordingly, the present investigation designed to evaluate the performance of selected bio-agents against Fusarium oxysporum f. sp. capsici. In-vitro evaluation of four biocontrol agents Trichoderma asperellum, Trichoderma harzianum, Pseudomonas fluorescens and Bacillus subtilis against F. oxysporum f. sp. capsici were assessed in dual culture technique. The highest growth inhibition percentage was also recorded in Trichoderma harzianum (82.08%), followed by Trichoderma asperellum (80.63%), Pseudomonas fluorescens (76.01%) and Bacillus subtilis (73.12%).
