Assessment of the influence of strobilurin application on the nutritional requirement for malting barley

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 interrelatedTo 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.本研究的整体目标为明确嘧菌酯类杀菌剂（strobilurin fungicide）施用对啤酒大麦（malting barley）氮素需求量的影响。该总目标下设若干相互关联的子研究目标，具体如下： 1. 评估相较于常规三唑类杀菌剂（triazole fungicide），嘧菌酯类杀菌剂对啤酒大麦氮素需求量的额外影响，本质上为量化病害管理与氮肥施用之间的交互作用； 2. 探明采用嘧菌酯类药剂开展病害管理对冬小麦啤酒大麦（winter wheat malting barley）产量与品质的影响； 3. 计算结合籽粒品质（grain quality）考量时，嘧菌酯类药剂与氮肥施用方案的成本效益。
