摘  要：
【目的】筛选对梨树腐烂病防治效果最佳的药剂,为梨树腐烂病的绿色防控及科学防治提供依据。【方法】以19a(年)生‘早酥’梨为试材,通过田间试验比较10种药剂对梨树腐烂病刮除病斑后的治愈率、愈合宽度和复发率,对梨树腐烂病的防治效果进行筛选,将筛选出的较好药剂进行田间综合防治试验。【结果】拂蓝克、腐殖酸铜和40%氟硅唑乳油500倍液处理后治愈率较高,与其他药剂防效存在显著差异(α=0.05),拂蓝克、腐殖酸铜和甲硫·萘乙酸田间试验具有很好的防治效果。【结论】拂蓝克、腐殖酸铜和甲硫萘乙酸可作为梨树腐烂病田间综合防控药剂。

摘  要：
【Objective】In order to provide the theoretical basis for the comprehensive and scientific control of pear Valsa canker,the optimal effect was screened out.【Methods】The cure rate,healing width and recurrence rate of 10 kinds of fungicides on pear Valsa canker were compared by field experiment with 19 years old‘Early Crisp'pear.The control effect was screened,and the field comprehensive control effect experiment was carried out.【Results】After treated with Fluranc,Copper of Humic Acid and 40% Flusiazole Emulsifiable oil,the cure rate was significantly higher than other chemicals.A field comprehensive control experiment was carried out with Fluranc,Copper of Humic Acid and Methyl Thionaphthylacetic Acid,which showed the better effect.【Conclusion】It's suggested that Fluranc,Copper of Humic Acid and Methyl Thionaphthylacetic Acid could be used for controlling pear Valsa canker in production.
