There was no evidence that the use of strobilurin fungicides lowered grain protein relative to untreated crops, despite yield increases of over 30%, contradicting European work where strobilurin application lowered grain protein through yield dilution. In this study strobilurin treatment was associated with either no effect or higher grain protein levels relative to untreated crops fertilised with the same amount of nitrogen. However, there was a slight trend to suggest that strobilurin treated crops utilised higher N rates better than untreated crops since where there was a margin advantage to nitrogen application it tended to be greater with the strobilurin treatments.
