Effect of Straining Caused by Sapstreak Disease on Sugar Maple Log and Lumber Values

Abstract

Sapstreak, a killing disease of sugar maple (Acer saccharum Marsh.), caused by the fungus Ceratocystis coerulescens (Munch) Bakshi, was first described by hepting in 1944 in North Carolina. It was reported in the Lake States by Kessler and Anderson in 1960 and in the Northeast by Houston and Fisher in 1964. It has also been found on occasional yellow-poplars (Liriodendron tulipifera L.) in scattered locations in Tennessee and North Carolina (Roth et al. 1959). In 1963, Ohman and Kessler reported several new cases in the Upper Peninsula of Michigan, including one stand in which the incidence was probably about 10 percent. They also presented evidence indicating that the fungus enters primarily through root wounds caused by logging.
