摘要: Grapevine trunk diseases (GTDs) are the most widespread fungal diseases, affecting grapevines in all major growing regions of world, and their complete eradication is still not possible. Aiming to search alternatives avoid spread high incidence these present work intended molecularly identify grapevine endophytic community, phytopathogenic fungi associated with GTDs vineyards within Alentejo region, test potential antagonist microorganisms as biological control candidates against GTDs-associated fungi. community showed a wide variety GTDs' asymptomatic symptomatic plants, nine them previously described prevalent identified plants were Diaporthe sp., Neofusicoccum H. viticola. Almost also detected which shows importance investigating interactions communities confirms need for early diagnosis diseases. Direct inhibition antagonism tests performed among endophytes fungi, endophyte biocontrol agents. Our findings suggest that promising use due antagonistic activity mycelia growth some
