【摘要】 【目的】筛选抑制梨火疫菌(Erwinia amylovora)的药剂,为防控梨火疫病提供参考与依据。【方法】采用最低抑制浓度和抑菌圈比较的方法,对30种抑菌制剂进行筛选。【结果】内吸性抑菌制剂1.8%辛菌胺醋酸盐,有机类抑菌制剂3%噻霉酮(ME)、3%噻霉酮(WP)和30%壬菌铜,植物源类型制剂80%乙蒜素以及微生物制剂荧光假单胞杆菌3000,是室内试验对梨火疫菌抑菌效果较好的制剂。【结论】不同药剂之间、同一种药剂不同剂型之间抑菌效果差异较大,研究筛选得到的6种抑菌制剂可为梨火疫的防治提供参考。更多还原

【Abstract】 【Objective】 Fire blight(Erwinia amylovora) is one of the most devastating bacterial diseases of plant species in the Rosaceae family. Screening of the agents and microorganism preparation against fire blight bacteria can help prevent and control the disease.【Method】Thirty kinds of antibacterial agents and preparations were screened in the laboratory using the methods of minimum inhibitory concentration and bacteriostatic circle comparison.【Result】The results showed that among 30 kinds of agents, 1.8% symplectic bacteria amine acetate, 3% benziothiazolinone(ME) and 3% benziothiazolinone(WP), 30% nonyl bacteria copper, 80% ethylicin, and the microorganism preparation Fluorescence pseudomonas 300 billion spores per gram were the agents and microorganism preparation with better bacteriostatic effects.【Conclusion】 The antibacterial effects of different agents and different dosage forms of the same agent were significantly different. The six antibacterial agents obtained in this study can provide theoretical and practical basis for the quarantine control of fire blight.更多还原
