Powdery mildew, caused by Podosphaera aphanis, is an important disease of strawberries and currently its control in the UK is very dependent on conventional fungicides. A series of experiments were carried out to integrate conventional fungicides with biopesticides and biostimulants for mildew control. In 2015–2016, the biopesticides Sonata (Bacillus pumilis) and AQ10 (Ampelomyces quisqualis) achieved at least as good as or better mildew control where they were applied alone rather than alternated with or tanked mixed with conventional fungicides. Three mildew management programmes were evaluated in 2017 on an ever-bearer cultivar. In the B. pumilis based programme, the need for treatment and the choice of products were partially determined by predicted mildew risks. The incidence of mildew on leaves was very low in untreated plots with virtually no mildew observed in the other treated plots. By contrast, mildew on the fruit rose rapidly from 2 % in late July to >90 % in late August in untreated plots. In treated plots, the percentage of fruit with mildew did not rise above 3 % with the three managed programmes based on B. pumilis. There were no significant differences in total yield and marketable yield between the managed programmes and the routine fungicide programme, but all were significantly greater than the untreated control. Most of the unmarketable fruit in the untreated control was due to infection with powdery mildew. The results suggested that strawberry powdery mildew can be effectively managed by the integrated use of biopesticides, biostimulants and conventional fungicides.

由Podosphaera aphanis引起的白粉病是草莓的一种重要病害，目前在英国的防治非常依赖常规杀菌剂。进行了一系列实验以将常规杀菌剂与生物农药和生物刺激剂结合以控制霉菌。在 2015-2016 年，生物农药奏鸣曲 ( Bacillus pumilis ) 和 AQ10 ( Ampelomyces quisqualis ) 在单独使用而不是与传统杀菌剂交替使用或与传统杀菌剂混合使用时，至少达到了与或更好的防霉效果。2017 年对一个常生品种评估了三个霉菌管理计划。在B. pumilis基于程序，治疗的需要和产品的选择部分取决于预测的霉菌风险。在未经处理的地块中，叶子上的霉菌发生率非常低，在其他处理过的地块中几乎没有观察到霉菌。相比之下，在未经处理的地块中，果实上的霉菌从 7 月下旬的 2% 迅速上升到 8 月下旬的 >90%。在处理过的地块中，使用基于短小芽孢杆菌的三个管理程序，水果的霉变百分比没有上升到 3% 以上. 管理计划和常规杀菌剂计划之间的总产量和可销售产量没有显着差异，但都显着高于未处理的对照。未经处理的对照中大部分滞销水果是由于感染了白粉病。结果表明，综合使用生物农药、生物刺激素和常规杀菌剂可以有效防治草莓白粉病。
