Fate of Dwarf Bunt Fungus Teliospores During Milling of Wheat into Flour
Cereal Chemistry, 1999ABSTRACTWheat 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 OF TILLETIA CONTRAVERSA, THE CAUSE OF DWARF BUNT OF WINTER WHEAT
Canadian Journal of Botany, 1958The 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.

Growth and sporulation of the dikaryons of the dwarf bunt fungus in wheat plants and in culture
Canadian Journal of Botany, 1989In the wheat plants infected with dwarf bunt, sporulation occurs only in developing kernels. The dikaryon was isolated from infected kernels and from the rachis of infected spikes. The development of pathogenic hyphae and teliosporogenesis in vivo and in vitro is described.

Identification of New Pathogenic Races of Common Bunt and Dwarf Bunt Fungi, and Evaluation of Known Races Using an Expanded Set of Differential Wheat Lines [PDF]
Plant Disease, 2012 Pathogenic races of Tilletia caries and T. foetida, which cause common bunt of wheat (Triticum aestivum), and Tilletia contraversa, which causes dwarf bunt of wheat, have been identified previously by their reaction to 10 differential wheat lines, each containing single bunt resistance genes Bt1 through Bt10. The reactions of races to the differential

Effect of Winter Wheat Cultivar and Difenoconazole Seed Treatment on Dwarf Bunt
Plant Disease, 1995Four 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.

Effect of seed treatment in preventing transmission of dwarf bunt of winter wheat to new areas
Pesticide Science, 1990AbstractThe effectiveness of various fungicide formulations containing carboxin and thiabendazole in eradicating teliospores of Tilletia controversa (dwarf bunt) from winter wheat seed was evaluated in the laboratory and the field. In the laboratory tests, the viability of teliospores washed from treated infested seed was greatly reduced as compared to

Dwarf Bunt of Wheat in China: Potential Sites from Satellite Studies1
Agronomy Journal, 1986AbstractCommon 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 ...

Wheat dwarf bunt, one of the important international quarantine diseases, is caused by Tilletia controversa. Tilletia caries is a close relative species of T. controversa and the teliospore morphology and genomic structure of T. caries are very similar to those of T. controversa. In order to distinguish between them, a random amplified polymorphic DNA (

Barley Chromosome Location and Expression of Dwarf Bunt Resistance in Wheat Addition Lines
Plant Disease, 1996Barley (Hordeum vulgare) is resistant to dwarf bunt of winter wheat (Triticum aestivum) caused by Tilletia controversa. Nine wheat-barley addition lines were utilized to determine which barley chromosomes and chromosome arms carry resistance genes. The lines included six disomic addition lines, WB1, WB2, WB3, WB4 WB6, and WB7, and three ditelosomic ...

Tilletia controversa Kühn (TCK) is an important quarantine pathogen that causes wheat dwarf bunt and results in devastating damage to wheat production. The fungus is difficult to be distinguished from T. caries and T. laevis, which cause wheat common bunt, based on morphological, physiological and symptomatological characteristics of the pathogens. The
