1) Evaluate the integrated effects of fungicide treatment and genetic resistance on FHB, FDK, and DON; and 2) Evaluate the effects of postanthesis fungicide treatments of FHB and DON as influenced by cultivar resistance and disease intensity.
The trial will use six cultivars (four soft red and two soft white cultivars) possessing differing levels of susceptibility to FHB. The treatments will be inoculated and non-inoculated untreated checks, application of Prosaro (6.5 fl oz/A + 0.125% Induce) at 50% anthesis (Feekes 10.5.1), and three post-anthesis applications (2, 4, and 6 days after anthesis). In addition, we will include a pre-anthesis (10.5) application and a treatment where Prosaro is used 10.51 followed by an application of Caramba or Proline six days post-anthesis. The trial will have a split plot design and four replications. Individual plots would measure approximately 14 x 50 feet. FHB intensity will be assessed in each plot at the soft dough growth stage, Feekes 11.2.
