SUMMARY Apple chlorotic leafspot virus (CLSV) was detected in 27 of 109 hawthorn and three of 67 blackthorn plants sampled in various parts of Britain. The CLSV isolates possessed similar properties to those isolated from other rosaceous species but differed in the severity of symptoms they induced in woody indicators. No seed or aphid transmission of CLSV was detected. Prunus necrotic ringspot (PNRV) and prune dwarf (PDV) viruses were detected in four and three respectively of 67 blackthorn plants. The PNRV and PDV isolates were serologically closely related to isolates from cherry. Arabis mosaic virus was detected in one blackthorn plant, but plum pox virus was not found in any of the tested plants.
