 Sanitation practices like the pruning of symptomatic limbs and removal of infected trees can serve to eliminate sources of inoculum and limit the spread of the pathogen.Additionally, some fungicides have been shown to be effective at controlling disease.In a study on the chemical control of chestnut blight in "Castanea sativa", it was found that the external application of both copper oxychloride and carbendazim could reduce the rate of disease by almost 50%.
