Creator:: Grable, Carl Ivan
Abstract:: This study was initiated to determine the tolerance to copper of Aspergillus niger, Stemphylium sarcinaeforme, Monilinia fructicola and Fusarium oxysporum f. sp. lycopersici. Included were strains of the latter two fungi that were induced to tolerate relatively high levels of copper by continual culture on sublethal levels of the toxicant....

Creator:: Strand, Larry L.
Abstract:: Polygalacturonase produced by Fusarium oxysporum f. sp. lycopersici was purified by chromatography on DEAE cellulose, CM cellulose, and hydroxylapatite. Removal of large amounts of carbohydrate by chromatography on hydroxylapatite did not affect heat stability of the enzyme. A large proportion of the remaining carbohydrate appeared to be covalently linked to...

Creator:: Elson, Joseph Earl
Abstract:: An assay for fungicidal activity of sodium N-methyldithiocarbamate (Na-MDC) and its decomposition products was developed in which there was a minimum influence due to the widely varying physical properties of the compounds (i.e. vapor pressure and water solubility). Decomposition of the toxicant during the tests was measured and held to...

Creator:: Baldwin, Charles Harry
Abstract:: This investigation was undertaken to determine 1) the effects of various carbon sources in defined media on pectolytic enzyme production, 2) the effect of the incubation period on pectolytic enzyme activity, and 3) the development of improved methods for the purification and characterization of the polygalacturonases (PG) produced by Fusarium...

Creator:: Stromberg, Erik Leslie
Abstract:: Bioassays of acetone extracts from xylem tissue in tomato stems and corresponding reductions in Fusarium oxysporum f.sp. lycopersici race 1 or 2 populations within the stems suggest that fungitoxic materials within the xylem vessels of Bonny Best, Jefferson, and Marglobe tomato cultivars initially kill a portion of the inoculum conidia....

Creator:: Danko, Stephen John
Abstract:: The fungitoxicity of acetone extracts from the xylem of Fusarium wilt disease resistant tomato plants (cv. Jefferson) inoculated with Fusarium oxysporum f. sp. lycopersici was greatly influenced by environmental factors. Extracts obtained from plants 1 h after watering were 4-times more toxic than extracts from plants subjected to water stress...
