RESPONSE OF CELERY AND CELERIAC CULTIVARS TO INFECTION BY CERCOSPORA APII

摘要

Early blight is one of the most destructive diseases of celery, celeriac and smalage as well. In 2006-2008 18 celeriac and five celery cultivars were tested in field experiment for reaction to Cercospora apii. All the cultivars tested were found susceptible to infection (basing on applied disease severity scale). Moreover, the disease displayed substantial influence on fresh weight of leaves and roots. Mass reduction was variable, depending on year and cultivar, and reached the value up to 90% and 94% for leaves and roots respectively.
