McCain Y1 - 1992/05/01 UR - http://auf.isa-arbor.com/content/18/3/161.abstract N2 - When five sycamore cultivars (Bloodgood, Columbia, Liberty, Yarwood, and Saratoga 86-336-C), grown in 5 gallon containers, were exposed to natural infection by the sycamore anthracnose fungus, Apiognomonia platani, Bloodgood was significantly less affected than Columbia, Yarwood and Liberty. Saratoga 86-336-C was highly susceptible. In contrast, Bloodgood was highly suscepitible to powdery mildew, Microsphaería penicillata, while Yarwood displayed the highest degree of resistance to the disease. ER -
