The invention provides fungicidal compositions containing benzyl-tris(aryl)-phosphonium salts of the general formula ##STR1## in which R.sup.1 represents an optionally substituted alkyl or alkoxy group; R.sup.2 represents a hydrogen atom or an optionally substituted alkyl group; R.sup.3, R.sup.4 and R.sup.5 independently represent a hydrogen or halogen atom or an optionally substituted alkyl or alkoxy group; and A.sup.- represents an anion processes for the preparation of such compounds. Certain of the compounds of formula I are novel and the invention therefore also provides processes for the preparation of such compounds and their use as fungicides.
本发明提供了含有苯基三(芳基)膦鹽的杀菌组合物,其通式为##STR1## 其中R.sup.1代表可选取代的烷基或烷氧基;R.sup.2代表氢原子或可选取代的烷基;R.sup.3、R.sup.4和R.sup.5独立地代表氢原子或卤素原子或可选取代的烷基或烷氧基;A.sup.-代表阴离子,本发明还提供了制备这种化合物的过程。其中某些I式化合物是新的,因此本发明还提供了制备这种化合物以及它们作为杀菌剂的用途的过程。
