Abstract
Abstract Prunus stem pitting disease was first described and recognized as a specific, infectious disease in 1967 and is now known to affect a number of Prunus species. Apricot trees affected by stem pitting show stunted terminal growth and chlorotic, drooping leaves that curl upward and lengthwise. The lower trunk may become enlarged at ground level or below with very thick, spongy bark. Removal of the bark from the affected lower trunk reveals pits and grooves on the woody cylinder. Wood pitting begins below ground, then gradually spreads into the roots and the trunk above ground. Stem pitting is caused by certain strains of the tomato ringspot virus. The causal agent is soil‐borne and also graft transmissible but is not uniformly distributed through infected trees. Naturally infected apricot trees may show a slow decline, or rapid dieback of the terminal growth. The severity of symptoms is determined by the cultivar and the strain of tomato ringspot virus. Control measures for Prunus stem pitting should include: use of propagation material from healthy trees and rogueing of pitted trees in nurseries and orchards. Repeated use of infested nursery sites for stone fruit nurseries should be avoided
