The Canada Thistle (Cirsium arvense) is a common weed found in the USA and Canada where it causes many agriculture problems. Pseudomonas syringae pv. tagetis, the pathogen which causes severe chlorosis of the stem apex of these plants, has possibility for controlling the Canada Thistle. We examined various vegetative structures of both control and affected plants to determine the extent of Pseudomonas infection in the terms of microbe population size and distribution within the plant. A total of seventeen plants were harvested from four different sites in Ohio. Tissues from stem apex, green leaves, stem and rhizome were homogenized with M9 broth and spread onto both ...
