Herbicidal compositions containing a bisphosphonic acid compound of the formula ##STR1## wherein n is 0, 1, 2, 3, 4, 5 or 6, or an agrochemically acceptable salt or hydrolyzable ester thereof and methods of controlling undesirable plant growth using these bisphosphonic acid containing compositions. The herbicidal compositions exhibit desirable efficacy when applied to plants post-emergence, but exhibit little significant activity when applied to plants pre-emergence. Novel aza-bisphosphonic acid compounds are also disclosed.
含有式为##STR1##的双膦酸化合物的除草剂组合物,其中n为0、1、2、3、4、5或6,或其农药学上可接受的盐或水解酯,以及使用这些含有双膦酸的组合物来控制不良植物生长的方法。这些除草剂组合物在对植物进行出苗后施用时表现出良好的效果,但在植物出苗前施用时几乎没有显著活性。还公开了新颖的氮杂双膦酸化合物。
