咪唑啉酮类除草剂的应用及降解

咪唑啉酮类除草剂虽具有高效广谱的特点，但有较长的残留活性，长期使用会造成作物药害，并且会制约正常的作物轮作。因此，如何解决其残留问题已成为目前的重要课题。本文介绍了咪唑啉酮类除草剂的种类和特性，阐述了此类除草剂在杂草体内的作用方式、代谢机制、应用情况及其在土壤中的降解途径，并对该类除草剂的应用与降解研究进行了展望。

Applications of imidazolinone herbicide and its degradation

Imidazolinone herbicides were persistent in soil, although they are efficient and of broad spectrum. They will cause crop injury and restrict the normal crop rotation with long term use. So the studies on how to solve the residues of imidazolinone herbicides are very important. This paper introduced the types and characteristics of imidazolinone herbicides, described the action modes and metabolic mechanisms in weeds, applications of imidazolinone herbicides and degradation of the herbicides in soil. The future applications and researches on degradation were also discussed.
