Field evaluation of fluazinam against clubroot (Plasmodiophora brassicae) of cruciferous vegetable crops

摘要

Clubroot (caused by Plasmodiophora brassicae) is the most serious soilborne disease of cruciferous vegetable crops in Australia. It occurs in most of the major crucifer growing regions and is a serious threat to export industries. The disease is difficult to control and few chemicals are registered for this purpose. Fluazinam, a fungicide of the diarylamines group of chemicals has given good control of late blight, Phytophthora infestans (2) and powdery scab, Spongospora subterranea (1) in potatoes. The potential of fluazinam for controlling clubroot of broccoli was examined in a series of field trials in 1995-96.
