How to Manage Pests

Pests in Gardens and Landscapes

Virus diseases

Several virus diseases attack cherries, including prune dwarf virus, rasp leaf virus, necrotic rusty mottle, cherry prunus necrotic ringspot, and mottle leaf. Virus diseases are often difficult to distinguish from one another based on symptoms alone. In general, virus symptoms consist of various deformities such as curled, folded, pointed, tattered, or rosetted leaves. Leaves may be thickened or puckered, spotted, mottled, necrotic or chlorotic. Small, misshapen, or discolored fruit may be produced.

Solutions

Buy and plant virus-free and certified planting stock. After symptoms on plants occur, there is no practical control. Remove infected trees and replant.
