title: Stimulation by caffeic acid, coumalic acid, and corilagin of the germination of resting spores of the clubroot pathogen Plasmodiophora brassicae.
abstract: Some chemicals were examined for their effects on the germination of resting spores of the clubroot pathogen Plasmodiophora brassicae, and on the control of clubroots in Chinese cabbage. Caffeic acid, coumalic acid, and corilagin stimulated the germination of Plasmodiophora spores and prevented the formation of clubroots in Chinese cabbage. Clubroot might be controlled by agents with germination-stimulating effects.
