Effectiveness of Slurry Treatments in Controlling Individual Endothia parasitica Cankers on American Chestnut

Four different slurries of hypovirulent strains were used to treat virulent Endothia parasitica cankers on American chestnut growing at three locations in West Virginia. The slurries included: a mixture of debilitated white strains (B-type); a mixture of Italian strains o1 intermediate pathogenicity; a pigmented but debilitated mixture of strains (Jr -type); and, a general slurry containing a combination of all strains (General). New cankers were treated at monthly intervals as they developed from May to November by punching 0.5 cm holes to the cambium at 1 cm intervals around the canker margin.
