Puccinia Polysora

The main objective of this work was to evaluate the variability of the southern rust pathogen Puccinia polysora in Brazil, based on its virulence on a set of maize (Zea mays) cultivars. Sixty single pustule isolates, from different areas of occurrence of southern rust, were evaluated for their virulence to 50 maize experimental hybrids. Six cultivars showed a clear distinction between susceptible and resistant reaction, and were used to characterize the variability of the pathogen. Seventeen virulence patterns were identified among the 60 isolates tested. The most frequent virulence patterns identified, were observed in all locations of sampling, which suggests the absence of geographical differentiation among prevalent populations of P. polysora in Brazil.

Abstract A description is provided for Puccinia polysora. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Erianthus divaricatus, E. alopecuroides, Euchlaena mexicana, Tripsacum dactyloides (= T. monastachyum), T. lanceolatum, T. latifolium. T. laxum, T. pilosum, Zea mays. DISEASE: Rust of maize causing chlorosis and premature death of leaves and leaf-sheaths. GEOGRAPHICAL DISTRIBUTION: Africa (Tropical, South, and Madagascar), Asia (S.E.), Australia (Queensland), Australasia, N. America (S. and E.), Central America and W. Indies, S. America (N.) (CMI Map 237). TRANSMISSION: By air over relatively short distances (37: 657) and by infected or contaminated material via air transport over long distances (38: 591).

Asian Soybean Rust

Bacterial pustule has not been previously reported on soybeans in North Dakota, and is unlikely to pose a direct yield threat to soybeans in North Dakota. However, the disease can be mistaken for Asian soybean rust, leading to unnecessary fungicide application and economic loss to the grower. Accepted 3 September 2014. Published 13 October 2014.

Yield Trials

The wheat stripe rust pathogen occured on several experimental wheat lines planted at Quincy, FL in early February 2003. Several experimental lines in the 2003 Advanced Wheat A, the Advanced Wheat B, and the Uniform Southern Wheat Nursery yield trials then showed traces of stripe rust on the leaves of the plants. An unusually cool and wet winter and spring encouraged a scattered outbreak of stripe rust of wheat on susceptible experimental lines of wheat. This report constitutes the first documented case of stripe rust of wheat in Florida. Accepted for publication 22 February 2005. Published 4 March 2005.
