摘要

Anthracnose disease caused by fungal pathogen Colletotrichum capsici is considered to be one of the most destructive diseases in chilli cultivation as it infects and leads to complete destruction of the crop by infecting the mature fruit in the field and/or during the storage period. The management of the disease is difficult due to the absence of any resistant cultivar and effective fungicide. The current study was initiated to evaluate the antifungal efficacy of the biosurfactant produced by strain Pseudomonas aeruginosa JS29 for biological control of anthracnose disease. The results revealed significant disease reduction using biosurfactant in plant assay which were challenge-inoculated with the fungal spore. In vitro experiments clearly showed that the biosurfactant can effectively inhibit the growth of both spore and mycelia of the pathogen. Moreover, the biosurfactant can also effectively inhibit the fungal growth in detached-fruit assay in different storage conditions. The study confirmed that the biosurfactant has tremendous potential to become a viable, cost-effective and environment-friendly alternative for managing anthracnose disease in field and in post-harvest storage condition.
