Pseudocercospora heveae associated with the leaves of the rubber tree



Pseudocercospora heveae associated with the leaves of the rubber tree



Summa Phytopathologica 18(3-4): 283-286



Beginning in 1986, leaf spots in mature leaves of Hevea, rubber trees clone RRIM 600, were found in full grown rubber tree plantations localized in the Paulista platean (Brazil). The spots, 3-5 mm diameter in size were found on the upper side of the leaf and were circular to irregular, with a light brown center and dark margins or of a uniform reddish-brown colo. On the underside the coloration was an opaque dark brown. The occurrence of many leaf spots caused yellowing of the leaf and leaf drop. In these spots frutifications of Pseudocercospora heveae (Vincens) Deighton were found. This represents the first report of this fungus, in Brazil, outside of the Amazon Valley.
