Abstract

In the cultivation of chili plants, there are some pathogen fungi that often attack chili plants and can reduce productivity. The pathogenicity of the genus Colletotrichum sp. is so strong that it can reduce chili production in quantity and quality, the disease called antracnose diseasse. Fusarium oxysporum mold can also reduce the productivity of chili. Trichoderma sp. is known to have a major role in controlling plant diseases. The secondary metabolites produced by Trichoderma sp. play an important role in its antifungal activity. This research aims to find endophytic fungi Trichoderma sp which are potential as a biocontrol agent against F. oxysporum causing wilt disease in chilli. In this study, the antifungal activity of volatile and non-volatile secondary metabolites of endophytic fungi Trichoderma sp. was tested against F. oxysporum and Colletotrichum sp. Antifungal activity of secondary volatile endophytic fungi Trichoderma sp. is able to inhibit Colletotrichum sp. growth by 41.11% and F. oxysporum at 12.45%. While non-volatile metabolites with a concentration of 30% displayed the greatest ability to inhibit the growth of Colletotrichum sp. by 20.58% and F. oxysporum by 13.02%.
