Pythiurn spp. associated with cavity spot of carrots in Western Australia

Pythiurn spp. associated with cavity spot of carrots in Western Australia Cavity spot lesions on mature carrots from growers’ properties, and mature and maturing carrots from a disease nursery, were sampled for Pythium spp. Over 98% of the isolates were P. sulcatum; other species isolated were P. irregulare and Pythium ‘D’. P. coloratum was not found. In vitro pathogenicity tests on carrots showed that isolates of P. sulcaturn caused lesions while P. irregulare and Pythium ‘D’ did not. We conclude that P. sulcatum is the most common and most important species associated with cavity spot of carrots in Western Australia. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australasian Plant Pathology Springer Journals

Abstract

Cavity spot lesions on mature carrots from growers’ properties, and mature and maturing carrots from a disease nursery, were sampled for Pythium spp. Over 98% of the isolates were P. sulcatum; other species isolated were P. irregulare and Pythium ‘D’. P. coloratum was not found. In vitro pathogenicity tests on carrots showed that isolates of P. sulcaturn caused lesions while P. irregulare and Pythium ‘D’ did not. We conclude that P. sulcatum is the most common and most important species associated with cavity spot of carrots in Western Australia.
