The objective of this study was to identify and characterize the virus complex(es) that cause disease symptoms and develop a molecular based diagnostic tool to identify them. The disease is known to cause severe downward curling of the leaves, noticeably stunted shoots, leaf chlorosis, and crumbly fruit it is the only Rubus disease that requires bioassays for detection. and Canada, the causal agents of the disease have not been identified. ![]() Although the disease has been described back in 1895 and was one of the most destructive raspberry diseases throughout the U.S. RLCD has been reported to be caused by two separate viruses causing varying symptoms in black, purple, and red raspberry cultivars. is raspberry leaf curl virus which is a causal agent of the systemic disease known as raspberry leaf curl disease (RLCD). A raspberry virus on the quarantine list for Rubus exports from the U.S. An important factor when shipping propagated Rubus across the globe is the security of clean plant material verified through pathogen detection methods which is vital in preventing disease spread. ![]() ![]()
