How Can Genetic Control of Diseases Aid the Forest Manager

Forest diseases caused mortality and growth losses during 1952 of more than 5 billion cubic feet of growing stock and almost 20 million board feet of sawtimber in the continental United States, according to the Forest Service's Timber Resource Review (1958). Diseases were responsible for 45 percent of the losses from all causes, including fire and insects. In the South, fusiform rust alone accounted for 97 million cubic feet of growing stock and 281 million board feet of sawtimber. The situation is probably not any better today. Obviously, we must improve our control of forest diseases if we are to obtain maximum production on our forest lands.
