Aims We investigated potential mechanisms by which a seed microbiome recruited from vermicomposted dairy manure alters Pythium aphanidermatum zoospore mediated pathogenesis in cucumber. Methods Bioassays were conducted to measure arrival of zoospores at the seed surface via qPCR and subsequent seedl...
