Nematode injury to the roots of trees and vines frequently is responsible for the appearance of aboveground symptoms of disease. These symptoms are variable since their expression may be influenced by such factors as soil type, soil fertility, irrigation practice, presence of other root parasites, age of the plant, and the severity of the root injury.
