Similar experiment – different conclusion; a response to the recent proposition of Septoria lepidii as a potentially important biological control agent for weedy species of Lepidium in North America

Abstract

ABSTRACTFollowing preliminary host-specificity testing Septori lepidii Desm. was recently proposed as a potentially important biological control agent for invasive Lepidium species in North America. Conversely, a previous, unpublished assessment of S. lepidii for biocontrol of Lepidium latifolium found the pathogen to be unsuitable due to infection of the American native Lepidium huberi.
