Sugarcane smut is caused by the fungus, Ustilago scitaminea Sydow, and it is one of the most serious diseases of sugarcane (Comstock, 2000). The disease has had a long history of spread around the world. BSES recognised the threat from smut and prepared a contingency plan in 1997 (Croft and Magarey, 1997) and commenced screening of Australian varieties for resistance to smut in Indonesia in ...

Ustilago scitaminea Sydow, which causes sugarcane smut disease, has been spreading throughout Africa and America since the 1950s. The objectives of the present study were (1) to confirm and further describe the global population structure of U. scitaminea on the basis of a larger number of isolates and (2) to infer its reproduction system.

Tissuecultured plantlets of three sugarcane (Saccharum spp.) cultivars having a known field smut reaction were screened for susceptibility to Ustilago scitaminea HP Sydow. Plantlets were inoculated with μ l of a suspension of equally mixed quantities of plus and minus mating type sporidia of U. scitaminea at concentrations ranging from 1 × 101 to 1 × 106 cells.

Sugarcane smut caused by Ustilago scitaminea Sydow was first reported in Hawaii in 1971 (Byther et al., 1971), although it had been a serious disease in other parts of the world for many years. In susceptible varieties it can spread rapidly, cause significant yield losses and reduce cane stands to unmillable grassy stalks. In Hawaii, the disease is controlled by continued monitoring of seed ...

Le charbon de la Canne à sucre, Ustilago scitaminea Sydow, a été observé pour la première fois en 1877 au Natal (Afrique du sud), puis il a été signalé en Argentine en 1940 [10]. En 1943, il était devenu la principale maladie de la Canne à sucre dans ce pays [4]. Le champignon est actuellement introduit dans tous les pays canniers du monde. Il est cosmopolite, présent jusque dans ...

Germination of chlamydospores of Ustilago scitaminea Sydow is typical of the Ustilaginaceae only on rich nutrient media such as potato dextrose agar. On sugar cane surfaces sporidia are rarely produced; the promycelia give rise directly to infection hyphae. This atypical germination sequence also takes place on nonnutrient media and on media containing only sugars (mannose, sucrose, lactose).
