STUDIES ON THE CONTROL OF DWARF BUNT IN WINTER WHEAT
Canadian Journal of Plant Science, 1961The 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 ...

Dwarf bunt on rye in Czechoslovakia.
Česká Mykologie, 1965The article reports the first confirmed occurrence of Tilletia controversa (dwarf bunt) on rye in Czechoslovakia, found in 1963 near Slovenská Ľupča. The disease is important from a phytopathological perspective and spreads via infected seeds and residues.

Fatty acids in teliospores and mycelium of the dwarf bunt fungus, Tilletia controversa
Phytochemistry, 1971Abstract Teliospores of the dwarf bunt fungus contain about 35% lipids; free fatty acids accounting for 52% and bound fatty acids 26% of the total lipids. Lipids make up 5·8% of the dry weight of the mycelium, with free fatty acids accounting for 48% and bound fatty acids 14% of the total lipids.

Difenoconazole Seed Treatment for Control of Dwarf Bunt of Winter Wheat
Plant Disease, 1993We 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.

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.

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.

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

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 ...
