Abstract

Phosphonium stannates of the formula I EQU [(R.sup.1).sub.a (R.sup.2).sub.b P].sub.n.sup..sym. [R.sub.q.sup.3 SnX.sub.r Y.sub.t ].sub.w.sup.n.crclbar. (I), in which the symbols R.sup.1, R.sup.2, R.sup.3, X, Y, a, b, n, q, r, t and w are as defined in the description, are active biocides. They can be used both in the preservation of materials and for protecting crop plants. Their water-solubility and their low volatility are particularly valuable properties.
