1,3,4-thiadiazole-2-carboxylic acid derivatives of the formula ##STR1## wherein R is C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -alkinyl or C.sub.3 -C.sub.6 -cycloalkyl, R.sub.1 is C.sub.1 -C.sub.6 -alkoxycarbonyl, aminocarbonyl, C.sub.1 -C.sub.8 -alkylaminocarbonyl, C.sub.3 -C.sub.6 -cycloalkylaminocarbonyl, di-C.sub.1 -C.sub.8 -alkylaminocarbonyl, cyclohexylmethylaminocarbonyl, alkoxyalkylaminocarbonyl, morpholinocarbonyl, pyrrolidinocarbonyl, piperidinocarbonyl or cyano, and n is 0.1 or 2. The compounds where n is 1 or 2 have both a high fungicidal and nematocidal activity. The compounds in which n is 0 are the starting products or intermediate products in making the compound in which a sulfonyl or sulfinyl group is present (n=1 or 2) but have also nematocidal properties of their own. All compounds of the invention avoid the undesirable environmental properties and other shortcomings of the prior art products, particularly those of the broadly used mercury compounds.
公式为##STR1##的1,3,4-噻二唑-2-羧酸衍生物,其中R为C.sub.1-C.sub.6-烷基,C.sub.2-C.sub.6-烯基,C.sub.2-C.sub.6-炔基或C.sub.3-C.sub.6-环烷基,R.sub.1为C.sub.1-C.sub.6-烷氧羰基,氨基羰基,C.sub.1-C.sub.8-烷基氨基羰基,C.sub.3-C.sub.6-环烷基氨基羰基,二C.sub.1-C.sub.8-烷基氨基羰基,环己基甲基氨基羰基,烷氧基烷基氨基羰基,吗啉羰基,吡咯烷羰基,哌啶羰基或氰基,n为0、1或2。其中n为1或2的化合物具有高度的杀菌和杀线虫活性。n为0的化合物是制备有磺酰基或亚磺酰基(n=1或2)化合物的起始产品或中间产物,但它们本身也具有杀线虫性质。本发明的所有化合物都避免了先前技术产品的不良环境特性和其他缺点,特别是广泛使用的汞化合物。
