Assessment of the influence of strobilurin application on the nutritional requirement for malting barley locations
Aims
  • The overall objective is to determine the influence of strobilurin fungicide application on the nitrogen requirement for malting barley.
  • Within this overall objective there are a number of component objectives that are interrelated
  • To assess the impact of strobilurin fungicide over and above conventional triazole fungicides on nitrogen requirement for malting barley, in effect to quantify any interaction between disease management and applied nitrogen. 
  • To measure the effect of disease management using strobilurins on the yield and quality of winter wheat malting barley.
  • To calculate the cost-effectiveness of strobilurin and applied nitrogen in relation to grain quality.
Key messages

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.
