摘要:

旨在筛选具有较好的水溶性、绿色环保、对植物病原菌具有较强杀菌性的杀菌剂。利用琼脂平板稀释法测定不同碳链长度的含吡啶杂环氯化铵(简称C8,C10,C12,C14,C16)阳离子表面活性剂对四种植物病原菌的离体杀菌活性,求出毒力回归方程,并计算有效抑菌浓度EC50值。结果表明:碳链长度为12的含吡啶杂环氯化铵(C12)阳离子表面活性剂对水稻纹枯病原菌的EC50=9.69×10 -3 g/L、对照药井岗霉素的EC50=7.02×10 -2 g/L;对西瓜枯萎病原菌的EC50=2.93×10 -2 g/L、对照药甲基布拖津的EC50=0.506 g/L;对苹果腐烂病原菌的EC50=1.57×10 -5 g/L、对照药苯醚甲环唑的EC50=3.50×10 -4 g/L;对番茄灰霉病原菌的EC50=1.85×10 -4 g/L、对照药菌恶唑的EC50=2.04×10 -3 g/L。即C12对四种病原菌的EC50值明显低于对照药剂,具有较好的杀菌活性,具有进一步研究的价值。通过相同试验方法进一步得到C12对四种病原菌的最小抑菌浓度(MIC)分别为0.094,0.091,0.083和0.087 g/L。为含吡啶杂环氯化铵阳离子表面活性剂对植物病原菌的防治研究提供依据。

Abstract:

The purpose is to screen fungicides with good water solubility, environmental protection and strong bactericidal effect on plant pathogens. The bactericidal activity of pyridine-containing heterocyclic ammonium chloride cationic surfactants with different carbon chain lengths (C8, C10, C12, C14, C16) against four kinds of plant pathogens was tested by agar plate dilution method. The toxicity regression equation was obtained, and the effective antibacterial concentration (EC50) was calculated. The results show that the pyridine-containing heterocyclic ammonium chloride cationic surfactants with a carbon chain length of 12 (C12) has a significant antibacterial activity for Rhizoctonia solani Kühn, watermelon Fusarium wilt, apple valsa canker and Botrytis cinerea Pers. with the EC50 of 9.69×10 -3, 2.93×10 -2, 1.57×10 -5 and 1.85×10 -4g/L, respectively. While the EC50 of the control drugs containing jinggangmycin, methyl butazine, difenoconazole and mycoazole for the above plant pathogens individually are 7.02×10 -2, 0.506, 3.50×10 -4 and 2.04×10 -3 g/L, respectively. The EC50 value of C12 for four pathogens are significantly lower than the control drugs, which has good bactericidal activity and further research value. The minimal inhibitory concentration (MIC) of C12 against the four plant pathogens are 0.094, 0.091, 0.083 and 0.087 g/L, respectively. It provides the basis for the research on the prevention and treatment of plant pathogens by pyridine-containing heterocyclic ammonium chloride cationic surfactants.

Key words: pyridine-containing heterocyclic ammonium chloride cationic surfactants, plant pathogens, in vitro, minimum inhibitory concentration, fungicidal activity
