| the effect of some organic substances on the mycelium of the fungus ustilago nuda (jens.) rostr. | research was performed for studying the effect of some organic compounds, considered by many authors as the products ob barley seed metabolism generated after anaerobic seed treatment, on the mycelium of the fungus ustilago nuda (jens.) rostr. the author examined the effectiveness of ethylacohol, acetaldehyde, acetic acid, succinic acid, lactic acid, and hydroquinone in concentrations from 1 m to 10(-6) m, and the effectiveness of extracts from disinfected seeds in doses from 10 g to 0.001 g/l. ... | 1976 | 1037055 |

| systemic fungicidal activity of 1,4-oxathiin derivatives. | treatment of pinto bean and barley seed with 1,4-oxathiin derivatives gave disease control by systemic fungicidal action of such pathogenic fungi as uromyces phaseoli and ustilago nuda. the two chemicals, d735 and f461, were highly specific and selective against the pathogens without injury of the hosts. | 1966 | 17779512 |
| fungicide selective for basidiomycetes. | concentrations of 2,3-dihydro-5-carboxanilido-6-methyl-1,4-oxathiin lower than 8 parts per million prevented mycelial growth of a number of basidiomycetes. by contrast, mycelial growth of various other fungi-phycomycetes, ascomycetes, and deuteromycetes-was 50 percent inhibited only by concentrations of 32 ppm or higher. two exceptions to this pattern of selective fungitoxicity were found:an isolate of rhizoctonia solani was not as sensitive as other basidiomycetes, and the deuteromycete vertici ... | 1966 | 17780003 |
| inheritance of carboxin resistance in a european field isolate of ustilago nuda. | abstract two carboxin-resistant field isolates of ustilago nuda from europe were crossed with a carboxin-sensitive field isolate from north america. meiotic tetrads isolated from germinating f(1) teliospores of one of the hybrids were tested for carboxin resistance and mating type. carboxin resistance was shown to be controlled by a single gene (cbx1r), because a 1:1 segregation of carboxin resistance was observed in all 27 tetrads. tetrad analysis indicated that the loci for carboxin resistance ... | 2000 | 18944606 |
| biological activity of sedaxane---a novel broad-spectrum fungicide for seed treatment. | sedaxane is a new broad-spectrum seed treatment fungicide developed by syngenta crop protection for control of seed- and soil-borne diseases in a broad range of crops. its physicochemical properties and activity spectrum have been optimised for use as a seed treatment providing both local and systemic protection of the seed and roots of target crops. | 2013 | 23044852 |
| fine mapping and identification of a candidate gene for the barley un8 true loose smut resistance gene. | the candidate gene for the barley un8 true loose smut resistance gene encodes a deduced protein containing two tandem protein kinase domains. in north america, durable resistance against all known isolates of barley true loose smut, caused by the basidiomycete pathogen ustilago nuda (jens.) rostr. (u. nuda), is under the control of the un8 resistance gene. previous genetic studies mapped un8 to the long arm of chromosome 5 (1hl). here, a population of 4625 lines segregating for un8 was used to d ... | 2015 | 25877520 |
