- 摘要:
- 以4种常见的有毒植物荨麻（Urtica fissa E.Pritz.）、曼陀罗（Datura stramonium Linn.）、马桑（Coriaria nepalensis Wall.）及商陆（Phytolacca acinosa Roxb.）为试材，采用抑菌圈法，研究了4种植物水提液对核桃黑斑病伴生病原菌成团泛菌（Pantoea agglomerans）抗菌抑菌活性，以期为核桃黑斑病的综合生物防治提供参考。结果表明：4种常见的有毒植物水提液均对该菌株具有良好的抗性，表现出较强的抑菌作用。其中马桑水提物对该病原菌的抑菌活性最佳，抑制率为44%。
- Abstract:
- Urtica fissa E.Pritz.，Datura stramonium Linn., Coriaria nepalensis Wall.and Phytolacca acinosa Roxb.were used as test materials，the antibacterial activity of four plant extracts against Pantoea agglomerans were tested by the method of bacteriostatic circle.The results showed that the growth of Pantoea agglomerans was obviously inhibited by biological pesticides.Such four poisonous plants could be candidates for the prevention and treatment of the associated pathogens causing blight on walnut.Coriaria nepalensis Wall.had the best inhibition effect and its inhibition rate was 44%.
