Plant quarantine significance of dwarf bunt of wheat to China

EPPO Bulletin, 1995
The adaptability of Tilletia controversa was studied in particular relation to China, where wheat is cultivated under various climatic conditions. Teliospore germination is closely influenced by temperature, light and soil humidity. Establishment of T. controversa depends on: (1) persistent low temperature (0–10°C) within the surface layer of the soil,

New Races of Common Bunt Useful to Determine Resistance of Wheat to Dwarf Bunt¹

Crop Science, 1978
Two new races of the common bunt fungus, Tilletia caries (DC.) Tul., were obtained from inoculations with teliospore mixtures. One race, T‐29, was virulent on wheat, Triticum aestivum L., cultivars carrying combinations of bunt resistance genes Bt1,2,7,9 and 10. The other race, T‐30, was virulent on cultivars carrying combinations of Bt 1,2,4,6,7,9 and

he organism causing dwarf bunt of wheat

Canadian Journal of Plant Pathology, 1954
When Fischer described Tilletia brevifaciens as the organism causing dwarf bunt of winter wheat, he showed that it was specifically distinct from T. caries (Fr.) Tul. However, he failed to indicate how his new species was separated from other species of Tilletia already described. Some of these species were restudied.

Fate of Dwarf Bunt Fungus Teliospores During Milling of Wheat into Flour

Cereal Chemistry, 1999
ABSTRACTWheat contaminated with teliospores of Tilletia controversa Kühn (TCK) was mixed with uncontaminated wheat and processed through the Kansas State University pilot mill. Two 50‐bu lots of the contaminated mixture were cleaned, tempered, and milled.

STUDIES ON THE CONTROL OF DWARF BUNT IN WINTER WHEAT

Canadian Journal of Plant Science, 1961
The development of satisfactory measures for the control of the dwarf bunt disease in winter wheat is complicated by the long persistence of the causal fungus in the soil and also by the occurrence of physiologic races. A brief review of literature dealing with these problems is presented.The present paper deals primarily with the use of fungicidal ...

Difenoconazole Seed Treatment for Control of Dwarf Bunt of Winter Wheat

Plant Disease, 1993
We evaluated difenoconazole (Dividend 3FS), thiabendazole (Mertect LSP), triadimenol (Baytan 30F), and carboxin plus thiram (Vitavax 200) as seed treatments for control of dwarf bunt (caused by Tilletia controversa) on the susceptible winter wheat (Triticum aestivum) cultivars Nugaines and Hatton.

Effect of Winter Wheat Cultivar and Difenoconazole Seed Treatment on Dwarf Bunt

Plant Disease, 1995
Four hard red and four soft white winter wheat cultivars (Triticum aestivum) of varying susceptibility to dwarf bunt (Tilletia controversa) were evaluated with and without difenoconazole seed treatment at 0.24 g a.i./kg. Difenoconazole provided complete control of dwarf bunt regardless of cultivar susceptibility.

Dwarf Bunt of Wheat in China: Potential Sites from Satellite Studies¹

Agronomy Journal, 1986
AbstractCommon bunts of wheat (Triticumspecies) caused by Tilletia caries(DC.) Tul. and T. foetida(Wall.) Liro are present in China, but dwarf bunt has not been reported. Beginning in 1974, wheat shipments from U.S. Pacific Coast states to the People's Republic of China were stopped because they contained spores of the dwarf bunt fungus (Tilletia ...

STUDIES OF TILLETIA CONTRAVERSA, THE CAUSE OF DWARF BUNT OF WINTER WHEAT

Canadian Journal of Botany, 1958
The occurrence and distribution of dwarf bunt of winter wheat in Ontario since 1952 is noted. While the severity of the disease has not been great, indications are that it is present in most areas of the province where winter wheat is produced in quantity and thus is of concern particularly to growers of seed wheat.The germination of T.
