Propiconazole (AlamoTM) is the only fungicide clinically evaluated and also proven efficient for this purpose. The majority of the tree losses in the oak wilt facilities occur from the activity of the virus through origin grafts from infected trees to healthy and balanced ones. This can be avoided by establishing an obstacle line around the infected location, which includes an 8-inch trench dug at least 48 inches deep between contaminated and healthy oaks. The trench can be produced using a commercial ditching equipment, a rock saw or a backhoe.
