The effects of the soilborne pathogen Fusarium oxysporum and the bulb mite Rhizoglyphus robini on onion sprout survival were experimentally tested in pots and an in-vitro bioassay (Petri dishes). Survival after 8 weeks in potted plants although significant, was subtle. However in the invitro bioassay, within 4 days we detected severe additive effects of the pathogen and mite on onion sprout rootlet growth. The importance of host-plant, fungi and mite interactions with respect to control are discussed.
