Seedborne Black Aspergillus Species As Maize Seedling Pathogens: Role Of Fumonisin Production And Interaction With Soilborne Pythium Species, Laura Kaelia Weieneth Jan 2015

Seedborne Black Aspergillus Species As Maize Seedling Pathogens: Role Of Fumonisin Production And Interaction With Soilborne Pythium Species, Laura Kaelia Weieneth

Graduate Theses and Dissertations

Twenty-six strains of black Aspergillus (Aspergillus section Nigri) were studied as seedling pathogens of maize. There were two major research components. The first component was an evaluation of the pathogenicity of isolates from several black Aspergillus species and a comparison of the pathogenicity of isolates with and without fumonisin production. This was accomplished by testing inoculated seeds in warm germination and cold tests, and by evaluating growth of inoculated seeds in rolled paper towel assays. In the second component, four of these species were selected for evaluation of interactions between Aspergillus and Pythium as a seedling disease complex in maize ...


Effectiveness Of Foliar Fungicides By Timing On Hybrid Corn, Alison E. Robertson, John M. Shriver, David Rueber Jan 2013

Effectiveness Of Foliar Fungicides By Timing On Hybrid Corn, Alison E. Robertson, John M. Shriver, David Rueber

Iowa State Research Farm Progress Reports

Fungicide use on hybrid corn has increased considerably in the past several growing seasons, primarily due to reports of increased yields, even in the absence of disease and higher corn prices. A number of fungicides are registered for use on corn. The objectives of this project were to 1) assess the effect of timing of application of fungicides on standability, 2) evaluate the yield response of hybrid corn to foliar fungicide application, and 3) discern differences, if any, between fungicide products.
