 Thus, the spread of the mycovirus in American "C. parasitica" populations are inhibited by vegetative incompatibility, an allorecognition system that inhibits the fusion of hyphae between individuals that are genetically distinct at specific loci.Recently, however, "super mycovirus donor strains" of "C. parasitica" have been engineered to overcome this incompatibility system and could potentially be employed as a method of biological control.In addition to biocontrol, chestnut blight can also be managed by sanitation practices and chemical control; however, such management strategies are only feasible on a small scale, such as in an orchard.
