三唑并嘧啶磺酰胺类除草剂的研究概况

摘要

三唑并嘧啶磺酰胺类除草剂是将磺酰脲类除草剂通过脲桥的结构改造和修饰而得,它既保持了磺酰脲类除草剂的超高效性,又克服了一些磺酰脲类除草剂品种在土壤中残留期较长、易对后茬作物造成伤害等缺点.本文综述了三唑并嘧啶磺酰胺类除草剂的结构、主要品种、作用机理、应用研究和发展前景.%Triazolo[1,5-α]pyrimidine-2-sulfonanilide herbicides were achieved by modification of the urea linkage of sulfonamide herbicides.The advantages of super-efficiency of the sulfonamide herbicides were retained, and the disadvantages of long-term residue in soils were overcome.The structures, main varieties, mechanism, application and development perspectives of the triazolo[1,5-α]pyrimidine-2-sulfonanilide herbicides were reviewed in this article.
