Discoloration and Decay in Red Maple and Yellow Birch: Reduction Through Wound Treatment

Abstract Several chemicals were introduced into fresh increment borer wounds in red maple and yellow birch. After 3 years, study trees were felled and dissected. The chemicals generally reduced the extent of discoloration and decay in red maple and of discoloration in yellow birch. Althoughwide variations occurred, some chemicals appeared to retard development of discoloration by restricting entrance of air to the wound. Forest Sci. 17:402-406.
