概括
素 (PH3),硫化 (SF) 和甲基异硫酸 (MITC) 在控制松病 (PWD) 方面表现有前途. 将它们与甲基化物 (MB) 结合,可以显著减少MB的使用,并增强对松木线虫 (PWN) 的疗效.
科学领域:
- 农业科学 农业科学
- 林业林业 林业 林业 林业
- 遗体学 遗体学 是一个学科.
背景情况:
- 松病 (PWD) 是由松木线虫 (PWN) Bursaphelenchus xylophilus引起的,是对松树林的重大全球威胁.
- 甲基化物 (MB) 是一种常见的烟雾剂,但其使用受到限制.
- 需要替代性烟雾剂和组合策略来有效控制PWN.
研究的目的:
- 评估素 (PH3),硫化 (SF) 和甲基异硫酸盐 (MITC) 对PWN的杀菌效果.
- 研究将这些烟剂与MB结合的协同效应.
- 为了确定协同烟雾剂组合的最佳比率.
主要方法:
- 对单个烟剂 (MB,PH3,SF,MITC) 对松树进行比较性无毒杀菌试验.
- 对二进制烟雾剂组合的评估 (PH3+MB,SF+MB,MITC+MB,PH3+SF,PH3+MITC,MITC+SF). 这些组合的组合包括:
- 剂量减少分析和最佳协同作用比的确定.
主要成果:
- PH3,SF和MITC表现出与MB相当的杀菌活性.
- PH3,SF或MITC与MB的组合显示出显著的协同效应,将MB剂量减少至少60%.
- 确定了最佳的协同效应比率: 1:9 (PH3:MB), 1:9 (SF:MB), 3:7 (MITC:MB), 1:9 (PH3:MITC) 和 5:5 (SF:MITC).这些比率均为 1:9 (PH3:MB), 1:9 (SF:MB), 3:7 (MITC:MB), 1:9 (PH3:MITC) 和 5:5 (SF:MITC).
- 在MITC和PH3或SF之间观察到明显的协同作用.
结论:
- PH3,SF和MITC是MB对PWN控制的有效替代品.
- 将这些烟雾剂与MB结合起来,提供了一种减少MB依赖的策略.
- 协同作用,特别是MITC和PH3或SF之间的协同作用,支持在集成PWN管理中使用它们.

Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene
5.7K
Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.
