Anthracnose of banana is incited by Colletotrichum musae. It is recognized as one the most destructive diseases of mature and immature banana fruits, resulting in huge economic losses all over the world. Present research deals with screening some oils both in vitro and in vivo for their antifungal activity against C.musae. Clove oil (0.1µl/ml) completely arrested the conidial germination and mycelial growth of C. musae. Fenugreek and almond oil exhibited significant inhibition of mycelial growth, 61% and 57% at a concentration of 2µl/ml. However, olive oil was least inhibitory on the test fungi. Clove oil also a showed marked reduction in anthracnose lesions on banana fruits, thereby suggesting disease control. Scanning electron microscopy revealed severely damaged mycelium and conidia. FTIR studies show the presence of important bands representing phenols, terpenes, aldehydes, and ketones. Based on our findings; clove, fenugreek and almond oil demonstrated fungicidal and fungistatic activities against anthracnose pathogen. Hence, these oils can be considered as potential alternatives to chemical treatments.
香蕉炭疽病由香蕉炭疽菌引起。它被认为是成熟和未成熟香蕉果实最具破坏性的病害之一，在全球造成巨大经济损失。目前的研究涉及在体外和体内筛选一些油类对香蕉炭疽菌的抗真菌活性。丁香油（0.1微升/毫升）完全抑制了香蕉炭疽菌的分生孢子萌发和菌丝生长。胡芦巴油和杏仁油在浓度为2微升/毫升时对菌丝生长有显著抑制作用，分别为61%和57%。然而，橄榄油对受试真菌的抑制作用最小。丁香油还使香蕉果实上的炭疽病病斑显著减少，从而表明对病害有防治作用。扫描电子显微镜显示菌丝体和分生孢子受到严重破坏。傅里叶变换红外光谱研究表明存在代表酚类、萜类、醛类和酮类的重要谱带。基于我们的研究结果，丁香油、胡芦巴油和杏仁油对炭疽病病原菌表现出杀菌和抑菌活性。因此，这些油类可被视为化学处理的潜在替代品。
