Özet:

Endophytic fungi are able to infect a wide range of host plant, which this is in some cases in plants associated to endophytes have shown increased resistance to plant pathogens, particularly fungal pathogens. The research aimed to investigate of endophytic fungi e.g Aspergillus sp, Beauveria sp, Culvularia sp, and Trichoderma sp isolated from healthy branches of cocoa plant towards vascular streak dieback disease on Seedling of cocoa plant in the field condition. All of fungal endophytes isolates showed the suppression of VSD and significantly different. Endophytic fungi Curvularia sp. and Trichoderma sp. was isolated from the offshoots of the seedling of cocoa plant after three months of inoculation. The fungal endophytes Curvularia sp. and Trichoderma sp. are endophytic fungus which provide potential biological control for Vascular Streik Dieback (VSD).
