S2White pine blister rust (Cronartium ribicola, Fischer) is a virulent and potentially serious disease of eastern white pine (Pinus strobus, L.) Control of this introduced rust has been carried on since about 1910 in the eastern United States. Today, after more than 50 years of control effort, the occurrence of blister rust in this region is gratifyingly infrequent. Because of effective and continuing control programs, blister rust has been brought under control, and is not now a serious threat to pine management in most areas of the East. Yet, control must continue if blister rust is to remain under control in the future.S3.

Download Improvement in Butt-log Grade with Increase in Tree Size, for Six Hardwood Species Book in PDF, ePub and Kindle
S2Work carried out by the Northeastern Forest Experiment Station in West Virginia in the past 12 years provides useful information about the relationships between tree d.b.h. and butt-log grade. The upper logs are not included in the relationships. Being smaller and containing more knots, these upper logs are generally of lower grade than the butt logs. Thus the average grade of all material in the sawlog portion of the tree is generally lower than the average grade of the butt log. In the West Virginia data, species differences in d.b.h.-grade relationship are readily apparent. This inherent tendency for species to have different proportions of the various grades in logs of the same size is a familiar phenomenon to grade-conscious foresters who work with hardwoods. The results in this paper provide a quantitative evaluation of this tendency for six of the local species.S3.
