Phytophtora citrophthora was isolated from the blighted foliage of container-grown giant redwoods (Sequoiadendron giganteum) grown under overhead irrigation at a nursery in southerm California. The isolate caused both foliar blight and root rot when inoculated onto greenhouse-grown redwood seedlings. Scanning electron microcopy of the foliar blight stage showed that zoospores aggregate at and infect via stomata. Inoculation of roots of 1-mo-old seedlings resulted in a significant reduction in the mean dry weight of the foliage after 3 mo (51.1 and 33.6 g for the uninoculated and inoculated treatments, respectively) and a change in the morphology and distribution of the roots within the pots. Isolates of P. citrophthora from Penstemon, Ceanothus, and Citrus and an isolate of P. parasitica from Pinus pinea also caused foliar blight. |
