This invention relates to herbicidally active sulfonamide compounds, agriculturally suitable compositions thereof and a method of their use as general and/or selective herbicides or plant growth regulants. More specifically the herbicidally active sulfonamides of this invention have an ortho cyclic saturated or partially saturated group which includes a carbonyl or sulfonyl radical. In the most common situation, the control of undesired vegetation is desired to permit the growth of useful crops such as cotton, rice, corn, wheat and soybeans, to name a few. Unchecked weed growth in such useful crops can cause significant losses, reducing profit to the farmer and increasing costs to the consumer. In other situations, herbicides are desired which will control all plant growth. Examples of areas in which complete control of all vegetation is desired and areas around fuel storage tanks, ammunition depots and industrial storage areas. There are many products commerically available for these purposes, but the search continues for products which are more effective, less costly and environmentally safe.
本发明涉及具有除草活性的磺酰胺化合物、其农业适用组合物以及它们作为普通和/或选择性除草剂或植物生长调节剂的使用方法。更具体地,本发明的除草活性磺酰胺类化合物具有一个正交环饱和或部分饱和的基团,其中包括一个羰基或磺酰基基团。在最常见的情况下,控制不需要的植被是为了促进有用作物的生长,如棉花、稻米、玉米、小麦和大豆等。这些有用作物中的未受控制的杂草生长可能会导致重大损失,降低农民的利润并增加消费者的成本。在其他情况下,需要除草剂来控制所有植物生长。需要完全控制所有植被的区域的例子包括燃料储存罐、弹药库和工业储存区域。有许多商业上可用的产品用于这些目的,但仍在寻找更有效、更经济和环境安全的产品。
