Root rot peas in the Netherlands : fungal pathogens, inoculum potential and soil receptivity

Fungi associated to pea (Pisum sativum L.) root rot were studied. Fusarium and Oomycetes were most common. Fusarium solani f. sp. pisi, Fsp, was widely distributed and the most frequent fungus in roots of diseased crops. The pathogens Thielaviopsis basicola , Tb, and Aphanomyces euteiches, Ae, were new records for pea in The Netherlands. These pathogens showed physiological specialization on pea. Mycosphaerella pinodes and Phoma medicaginis var. pinodella were of ten found, mainly as blight diseases. For several root rot pathogens, seed infection was a source of primary inoculum. The disease p... Mehr ...
