The invention provides nematocide control diacylimide compositions which include compounds having the formula: ##STR1## where R and R' are selected from alkyl, alkenyl, haloalkyl and haloalkenyl having from 1-5 carbon atoms, being the same or different groups. The compositions of this invention show excellent agricultural nematocidal activity, and particularly, the control of endoparasitic and ectoparasitic worms, such as the root knot nematocide, which exist in the soil at some stage of their life cycles. The diacylimide compounds generally are prepared by reacting a suitable amide with an acyl halide. The acyl halide precursor may be prepared, if necessary, from the corresponding acid by reaction with a suitable halogenating agent, such as thionyl chloride. Similarly, a given amide may be readily prepared, for example, from the corresponding acyl halide by reaction with ammonia.
该发明提供了一种寄生虫控制二酰亚胺组合物,其中包括具有以下结构的化合物:##STR1## 其中R和R'从1-5个碳原子的烷基、烯基、卤代烷基和卤代烯基中选择,可以是相同或不同的基团。本发明的组合物表现出优异的农业寄生虫活性,特别是对内寄生虫和外寄生虫蠕虫的控制,例如存在于土壤中某个生命周期阶段的根结线虫。二酰亚胺化合物通常是通过将适当的酰胺与酰卤反应制备而成。如果需要,酰卤前体可以通过与适当的卤化剂(如氯化亚砜)反应从相应的酸制备而成。同样,给定的酰胺可以很容易地通过与氨反应从相应的酰卤制备而成。
