Clubroot (Plasmodiophora brassicae) became the main limiting factor of cabbage production in Semberia, one of the important producing region of this plant in Yugoslavia. This disease was probably introduced and spread by infected seedlings in all localities of cabbage producing area in the region. The damage increased very much in a relatively short time because of growing cabbage as a monoculture (cabbage being second crop after barley, wheat, ect), on acid soils and on irrigated plots. The efficacy of some fungicides has been tested against cabbage Clubroot on heavy infested fields by the parasite. Water solutions of fungicides were applied by three different methods: dipping of seedling root, drenching of transplanted plants, and a combination of two previous methods. There was no decrease of the disease attack by dipping seedling root in water solutions of the tested fungicides. In the comparison with untreated plots a significant decrease of the Clubroot infestation has been found in the treatments with envoit and benlate by using two other methods of application.
