Abstract

Since it first appeared in Tanganyika in 1957, red band needle blight has become a major forest disease around the world. Apparently spread by high altitude winds, the blight has been found killing Monterey and other pines in California's northwest coastal counties. About 30 pine species are susceptible. Caused by the fungus Dothistroma pini (sexual stage Scirrhia pini), the disease usually damages only young trees. Climate may hold the disease in check in most of California.
