This research discovered beneficial fungi naturally present in British Columbia vineyards that can protect grapevines from destructive diseases. The scientists identified seven different species of Trichoderma fungi, including two previously unknown species, and showed that some were highly effective at preventing infection through pruning wounds. This natural biocontrol approach could provide grape growers with sustainable alternatives to chemical fungicides. Impacts on everyday life: • Supports production of healthier grapes for wine and table consumption • Reduces need for chemical fungicides in agriculture • Advances sustainable farming practices • Helps protect economically important wine industry • Demonstrates value of discovering and utilizing beneficial organisms already present in local environments
