Garlic mustard is an invasive Eurasian biennial spreading in deciduous forests of North America. Garlic mustard plants in Ohio can be infected with a strain of Xanthomonas campestris, the causal agent of black rot disease in brassicas. I examined variation in susceptibility to X. campestris among garlic mustard populations, several native wild species, and agricultural crop varieties. Twenty-four garlic mustard populations were universally susceptible to X. campestris, though disease severity varied. Cardamine concatenata and Cardamine diphylla were susceptible but can phenologically escape infection in the field. Of the 14 agricultural crops tested, three cultivars (Raphanus sativus, Brassica rapa var. Rapa Hakurei, and cv - Brassica oleracea var. capitata) were susceptible to the X. campestris strain that infects garlic mustards. Nutrient availability enhanced disease susceptibility and severity, but light had a limited effect. A survey of 31 garlic mustard populations in Ohio, Kentucky, and Indiana revealed that X. campestris is established throughout a 120 km radial distance from Dayton, Ohio. The strain of X. campestris infecting garlic mustard in the Wright State University woods was identified by sequencing as X. campestris pv. incanae.
