    • The present invention relates to novel acrylate-type N-methyl E-2-(2-methylphenyl)oxymethyl)-6-methylphenyl-glyoxylamide O-methyl oxime represented by formula (1), its preparation method and its use as fungicides. The compound of the present invention has not only stronger fungicidal effect on plant pathogens at low concentrations but also broader fungicidal spectrum than the conventional fungicides. Especially, because the compound has excellent systemic and curative effect as well as no toxicity, it can be used as an efficacious agricultural fungicide. In addition, the compound of the present invention can be useful as environmental-friendly fungicide capable of causing less environmental pollution fungicide due to its strong fungicidal effect at low concentrations.
    • 本发明涉及由式(1)表示的新型丙烯酸酯型N-甲基E-2-(2-甲基苯基)氧甲基)-6-甲基苯基 - 乙醛酰胺O-甲基肟,其制备方法及其作为杀真菌剂的用途。 本发明的化合物不仅具有比常规杀真菌剂在低浓度下对植物病原体更强的杀真菌作用,而且具有更广泛的杀真菌作用。 特别是因为该化合物具有优异的全身和治疗效果以及无毒性,因此可用作有效的农药杀菌剂。 此外,本发明的化合物由于其在低浓度下具有强烈的杀真菌作用,因此可用作能够减少环境污染杀真菌剂的环保杀真菌剂。
