An anthracnose of celery caused by Colletotrichum orbicuLare (Berk. & Mont.) Arx

Abstract

Since May 1959, sporadic outbreaks of a h1therto undescribed disease of celery have been recorded from south-eastern Queensland. Although the disease has occasionally been serious in individual farms, it has not so far caused general heavy losses in celery-growing areas of Queensland. An anthracnose disease of celery caused by Colletotrichum orbiculare is described. Glasshouse pathogenicity trials show that three varieties of celery grown in Australia - White Plume, Solid White and South Australian White are susceptible to the disease.
