Susceptibility of Planetrees to Anthracnose and Powdery Mildew in California    (View PDF)

Pavel Svihra and Arthur H. McCain

Abstract: 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, Microsphaeria penicillata, while Yarwood displayed the highest degree of resistance to the disease.
