| 摘要 |
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.
