Abstract

The short needle disease of pines consists of dwarfing, crooking, twisting, and excessive elongation of random needles, failure of buds to develop, reduced lateral branch development and the premature casting of needles. The disease was initially associated with a power plant source of air pollution in the eastern United States during 1969; at that time the cause of the disease was unknown.
