摘要
[目的]探索4种杀菌剂对梨火疫病的田间防治效果与安全性。[方法]采用茎叶喷雾法在新疆库尔勒市香梨园进行了田间药效试验。[结果]4种杀菌剂的各处理对香梨花、果实安全。其中2%春雷霉素水剂100 g a.i./hm2处理和3%噻霉酮水分散粒剂112 g a.i./hm2处理对梨火疫病的防治效果分别为81.56%和78.63%。[结论]抗生素类杀菌剂2%春雷霉素水剂和有机杂环类杀菌剂3%噻霉酮水分散粒剂对梨火疫病田间防治效果较好,可作为今后田间防治梨火疫病选择化学药剂的依据。
[Aims] This study aims to explore the field control effect and safety of 4 fungicides on pear fire blight.[Methods] The field efficacy test of stem and leaf spray was carried out in Xiangli Garden, Korla city, Xinjiang.[Results] The treatments of four fungicides were safe for fragrant pear flowers and fruits.Among them kasugamycin 2%AS 100 g a.i./ha and benziothiazolinone 3% WG 112 g a.i./ha treatmentsindicated control effect on fire blight of 81.56%and 78.63%, respectively. [Conclusions] Antibiotic fungicide kasugamycin 2% AS and organic heterocyclic fungicide benziothiazolinone 3% WG had better control effect on pear fire blight in the field, which could be used as the basis for selecting chemical agents for control of pear fire blight in the future.
