摘要

Field experiments were conducted between 2003 and 2005 to compare the efficacy of five interactive decision support systems (DSSs) (DESSAC, PLANT-Plus, proPLANT Expert, CerDis and Crop Protection Online (CPO)) and an in-crop system (Septoria Timer) to schedule fungicide applications to winter wheat cultivars (Madrigal and Claire) for the control of Mycosphaerella graminicola. The effectiveness of the crop management programmes proposed by the DSSs was compared with that of standard 2-spray programmes applied at GS 37 and 65 and 3-spray programmes applied at GS 32, 39 and 65. Compared with the 3-spray programme, the programme scheduled by CPO advised application of the least active ingredient to the six trials over three seasons, while together with the Septoria Timer it also advised the least number of applications (average 2-3 per crop). The PLANT-Plus system advised the highest input of active ingredient and the highest number of applications (average of 4.0 per crop). The interactive DSSs responded to cultivar susceptibility to M. graminicola by scheduling more applications to the susceptible cv. Madrigal compared with the moderately resistant cv. Claire. Whether control of M. graminicola is expressed as reduction in the proportion of necrosis per leaf or a reduction of the area under the disease progress curve, the 3-spray programme provided the most effective control. The Septoria Timer provided a similar level of control. For the remaining programmes, the effectiveness of control varied with observation date, leaf and cultivar. The 2-spray programme provided the least successful control. Fungicide application significantly increased grain yield each season. The fungicide scheduling programme that provided the highest grain yield varied by cultivar and season. Grain specific weight was enhanced by fungicide application compared with the untreated control, except for cv. Claire in 2004. The fungicide scheduling programme that provided the highest specific weight varied with cultivar and season. The highest average margin over fungicide cost was provided by the Septoria, Timer.

Graminicola的品种易感性作出反应。 Madrigal与中等抗性CV相比。克莱尔。无论是对麦葡聚糖的控制是否表达为每叶坏死比例的比例或疾病进展曲线下的区域的减少，3喷雾计划提供了最有效的控制。 Septoria定时器提供了类似的控制水平。对于剩余的计划，控制的有效性随观察日期，叶和品种而变化。 2喷雾计划提供了最不重要的控制。杀菌剂应用每个季节的谷物产量显着增加。杀菌剂调度计划提供了品种和季节变化的最高谷物产量。除了CV之外，杀菌剂应用与未处理的对照相比，杀菌剂申请增强了晶粒特异性重量。克莱尔于2004年。杀菌剂调度计划提供了最高的特异性重量与品种和季节不同。 Sememer，Timer提供的杀菌剂成本的最高平均余量。
