Cherry rasp leaf virus (CRLV) is a plant pathogenic virus of the order Picornavirales, family Secoviridae, genus Cheravirus.http://www.virology.net/Big_Virology/BVFamilyGroup.html Family Groups—The Baltimore Method
Causes CRLV can be transmitted by nematode (Xiphinema Americana), mechanical inoculation, grafting, or seed (10–20%).ICTVdB—The Universal Virus Database:
Symptoms Leaves become studded with projections or enations between the lateral veins and all along the midrib. As a result, the leaves become deformed and folded, looking very narrow. The face of the leaf has a bumpy texture as a result of the enations on the underside.
Initial infections begin at the lower branches and patches of the tree will show symptoms. Lateral (tree-to-tree) infection is slow and fruit production is reduced. Severe infection may result in the death of the tree.USDA-ARS. 1976. Virus Diseases and Noninfectious Diseases of Stone Fruits in North America. Agriculture Handbook 437.
