This invention relates to alpha-(2-alkoxyphenyl)-alpha-alkyl-1H-1,2,4-triazole-1-propanenitriles and derivatives, their enantiomorphs, acid addition salts and metal salt complexes. These compounds, enantiomorphs, salts and complexes are highly active broad-spectrum systemic fungicides effective in controlling phytopathogenic fungi such as barley helminthosporium, cucumber downy mildew, cucumber powdery mildew, grape downy mildew, peanut cercospora, rice blast, wheat powdery mildew and wheat stem rust. The compounds have protective and curative activity against rice blast when they are applied foliarly or systemically and have superior residual activity against rice blast via foliar application.
这项发明涉及α-(2-烷氧基苯基)-α-烷基-1H-1,2,4-三唑-1-丙腈及其衍生物,它们的对映体,酸盐和金属盐络合物。这些化合物,对映体,盐和络合物是高活性的广谱系统杀菌剂,对控制大麦谷物镰刀菌、黄瓜霜霉病、黄瓜白粉病、葡萄霜霉病、花生锈病、水稻稻瘟病、小麦白粉病和小麦锈病等植物病原真菌有效。这些化合物在叶面或全株施用时对水稻稻瘟病具有保护和治疗活性,并且通过叶面施用具有优越的残留活性对抗水稻稻瘟病。
