Sclerotium rolfsii is more prevalent in the southernmost than in the other apple-growing areas of Georgia. Recovery of the fungus from naturally infested areas is inconsistent, however. Captafol effectively reduces growth of S. rolfsii at 100 ppm in vitro and as a drench treatment. Both captafol and copper sulfate reduce recovery of S. rolfsii from roots and trunk tissue of apple trees.
