New ELISA test to distinguish between Markus and Dideron strains of plum pox potyvirus
A new ELISA test which allows to distinguish between Markus and Dideron strains of plum pox potyvirus (EPPO A2 quarantine pest) has been tested in France. This new ELISA test gave good results and can be used routinely, in particular for surveys. In 1999, 100 Prunus samples (apricot, cherry, plum and peach) collected from Languedoc-Roussillon were tested by this method. Results showed that a majority of peach samples were infected by Markus strain.
