Endophytic Fusarium spp. affect yield, but can they be a solution for Botrytis control in vineyard production?

Grapevine plants can form mutualistic associations with endophytic fungi. However, to date, there is not much information on the influence of endophytic Fusarium isolates on grapevine growth, oenological characteristics or their capabilities to suppress disease. In the present study, it was demonstrated on two grapevine varieties tested in a field experiment in vineyards under natural conditions that three isolates of Fusarium do indeed enter into mutualistic interactions with their host. Results indicate a complementary relationship between grape yield and Fusarium colonization. Plants treated with Fusarium isolates not only showed increases in yield, but also had fewer losses due to shriveling and also had more vigorous development under unfavorable weather conditions. Furthermore, treatment with isolates of Fusarium solani and Fusarium subglutinans resulted in significantly lower gray mold incidence at rates of 80 %.
