    • 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 wherein 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.
    • 式I的1,3,4-噻二唑-2-羧酸衍生物其中R是C 1 -C 6 - 烷基,C 2 -C 6 - 烯基,C 2 -C 6 - 炔基或C 3 -C 6环烷基,R 1是C 1 C 1-6 - 烷氧基羰基,氨基羰基,C 1 -C 8 - 烷基氨基羰基,C 3 -C 6 - 环烷基氨基羰基,二-C 1 -C 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,吗啉代羰基,吡咯烷基羰基,哌啶子基羰基或氰基,n为0.1或2.其中n为 1或2具有高杀菌和杀线虫活性。 其中n为0的化合物是制备其中存在磺酰基或亚磺酰基的化合物(n = 1或2)的起始产物或中间产物,但也具有自己的杀线虫性质。 本发明的所有化合物避免了现有技术产品,特别是广泛使用的汞化合物的不良环境特性和其它缺点。
