ABSTRACT:
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.
