Phoma exigua var. foveata is present in Poland
Studies were carried out in Poland on seed potatoes of native cultivars, from 1981 to 1987. Among 326 samples tested, 15 % showed infection by Phoma exigua var. foveata (EPPO A2 quarantine pest), 10 % by P. exigua var. exigua and 18 % by P. eupyrena. This confirms earlier 'unconfirmed records' on the occurrence of P. exigua var. foveata in Poland.
