【摘要】 采用生长速率测定法室内测定了 4种N 硝基 N 取代酰基 2 ,4 ,6 三氯苯胺类新化合物(F1～F4 )对多种植物病原真菌的抑菌活性。结果显示 ,F1,F2 ,F3对植物病原真菌的抑菌活性较弱 ,只有F4 (N 硝基 N 六氢吡啶酰基 2 ,4 ,6 三氯苯胺 )对花生白绢病病原菌、油菜菌核病病原菌有较强抑制作用 ,在 7 5× 10 - 4g·L- 1浓度下 ,对两种病原菌的校正抑制百分率分别为80 0 %和 86 2 %。本文对抑菌机制也进行了初步讨论更多还原

【Abstract】 By means of growth velocity method,the activity four new N nitroanilinelic compounds(F 1 F 4) to plant pathogenic fungi were tested.The result showed that the compounds F 1,F 2 and F 3 exhibited weak inhibitory activity to plant pathogenic fungi.The compound F 4 exhibited good inhibitory activity against Sclerotium rolfsii and Sclerotinia sclerotiorum. The efficiency was 80% and 86 2% respectively.The mechanisms of four new N nitroanilinelic Compounds to plant pathogenic fungi were also discussed in this article.更多还原
