To assess the impact of commercially available seed treatments on wheat yield and quality.
This trial showed considerable infection of striperust at flag leaf stage through to grain filling stage.There were visual differences in stripe rust levels between the control and stripe rust treatments at flag leaf stage. A foliar fungicide application would have undoubtedly protected the plant in the later growth stages, thereby providing higher yields. The soil root disease test showed no
problem with the root diseases listed above. One disease, which cannot be commercially tested for at this stage, is pythium. Dividend does not claim to have any effect on stripe rust so the increase in yield in the Dividend treatment could be attributed to pythium. The other treatments have clearly had a yield benefit from stripe rust suppression, as this was the only visible foliar disease in the trial. The trial will be extended in 2005 to include foliar fungicide applications and other combinations of products used in this trial.
