DescriptionThe history of Scleroderris canker in the Lake States Region is reviewed. U.S.D.A. Forest Service studies on the distribution, degree of infection, rate of spread, and general biology of the disease organism are described. On National Forest land in Upper Michigan and northern Wisconsin, where the disease is most serious, 66 percent of the red pine plantations and 88 percent of the jack pine plantations are infected with Scleroderris lagerbergii. In infected stands Scleroderris canker is the main identified cause of tree mortality. The life cycle of S. lagerbergii is described as well as proposed control methods and future studies planned.
