Compositions for regulating the growth of plants containing phospholanium salts of the formula: ##STR1## in which R.sup.1 is optionally substituted alkyl, alkenyl, alkynyl or cycloalkyl, or aralkyl which is optionally substituted in the aryl part, R.sup.2 is optionally substituted alkyl, alkenyl, alkynl or cycloalkyl, or aralkyl which is optionally substituted in the aryl part, R.sup.3 is halogen or alkyl, n is 0, 1 or 2, and A.sup.- is one equivalent of an anion of a nonphytotoxic acid Are outstandingly useful to inhibit, enhance, or modify the growth of plants, even at relatively low dosages.
含有磷酸氨盐的植物生长调节剂组合物的化学式为:##STR1## 其中,R.sup.1是可选的取代烷基、烯基、炔基或环烷基,或者是在芳基部分可选的取代的芳基烷基;R.sup.2是可选的取代烷基、烯基、炔基或环烷基,或者是在芳基部分可选的取代的芳基烷基;R.sup.3是卤素或烷基;n为0、1或2;A.sup.-是非植物毒性酸的一个阴离子当量。这些组合物在相对较低的剂量下,可以杀菌、促进或改变植物的生长,非常有用。
