Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...

When faced with foliar fungal diseases in cereals, control and damage limitation strategies need to be tailored to the rainfall region, variety resistance status and the disease... Foliar fungal diseases of wheat and barley, such as stripe, leaf and stem rust as well as powdery mildew, can result in substantial losses in all but resistant varieties if left unchecked (Figure 1)... yield increases of 56 per cent have been obtained from GS71 (watery ripe stage) applications in research conducted in WA...

In order to take account of any possible product shortages in an epidemic year, fungicide products were evaluated across a range of rates (N.B. the use of fungicide or use at rates lower than the label does not constitute a recommendation in this report)... Seven fungicides were evaluated at four trial sites: 1...
