摘要： 对设施内草莓白粉病的发生时期、品种抗性做了观察，结果表明，2-3月，草莓白粉病在叶片上发生一般，进入4月，白粉病明显加重，至5月上旬叶片发病达到高峰。同时看出3月之前，果实发病较轻，进入4月后果实发病明显加重。19个草莓品种中，8个高抗、5个抗病、3个感病、3个高感，品种间存在明显的抗病差异性。对9种药剂的筛选试验结果表明，苯醚甲环唑、己唑醇药剂的防效在80%以上，控制病害的效果较好。

Abstract: Study on occurrence period and variety natural disease resistance of strawberry powdery mildew in greenhouses, The results indicate that strawberry powdery mildew occurred is general on leaf in February to March, disease becomes aggravated in April, and the highest could reach in May. Results also showed that disease occurrence was milder on fruit before March, and disease condition becomes more serious after April. The high resistance, resistant, susceptible, highly susceptible were 8, 5, 3 and 3 of 19 strawberry varieties, there was obvious resistance difference between cultivars. Study on screening out fungicides proved that the effect of nine fungicides such as difenoconazole and hexaconazole was above 80%, had a better effect on strawberry powdery mildew.
