Thousand cankers disease -- What have we learned?

Abstract

Thousand Cankers Disease (TCD) represents a serious threat to black walnut, an important nut and timber tree in the eastern United States. TCD was first described as a lethal disease for most walnut species in 2009. A webinar sponsored by the USDA Forest Service State & Private Forestry and Forest Health Protection, the Walnut Council, and the Purdue University Department of Entomology on March 28, 2013, suggests we are making progress toward knowing the causes of the tree disease, detection of diseased trees and causal organisms, origin of the beetle and fungus, and treatments to permit transport and sale of products from infested wood.
