This application relates to ortho-carboxylate ester sulfonylureas which are useful as agricultural chemicals and in particular have high herbicidal activity while showing tolerance to certain crops.

Herbicidal sulfonamides

Benzylsulfonylureas and arylsulfamoylureas are useful as pre-emergent and post-emergent herbicides and as plant growth regulants.

Benzylsulfonylureas and arylsulfamoylureas

This invention relates to certain herbicidally active sulfonamide compounds, suitable agricultural compositions thereof and a method for their use as general and/or selective preemergence or postemergence herbicides or plant growth regulants.

A class of ortho-alkyl- and ortho-alkenyl-substituted benzenesulfonamides are useful as general or selective pre-emergent or post-emergent herbicides and as plant growth regulants.

Herbicidal ortho-alkyl- and ortho-alkenyl-substituted benzenesulfonamides

This invention relates to certain sulfonylurea compounds having a ring structure, which is attached ortho to the sulfonyl bridge through a double bond, agricultural compositions thereof and a method of their use as general preemergence and/or postemergence herbicides or plant growth regulants.

This invention relates to herbicidally active sulfonamide compounds having an ortho cyclic saturated or partially saturated group which includes a carbonyl or sulfonyl radical.

Herbicidal ortho-heterocyclic thiophenesulfonamides

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.

Herbicial ortho-heterocycllic sulfonamides

Herbicidally active pyrazolesulfonamide compounds having an ortho cyclic saturated or partially saturated group which includes a carbonyl or sulfonyl radical having utility as herbicides and plant growth regulants.

Herbicidal ortho-heterocyclic pyrazolesulfonamides

Herbicidally active pyridinesulfonamide compounds having an ortho cyclic saturated or partially saturated group which includes a carbonyl or sulfonyl radical display utility as herbicides and plant growth regulants.

Herbicidal ortho-heterocyclic sulfonamides

Herbicidal ortho-alkyl-and ortho-alkenyl substituted benzenesulfonamides

Benzenesulfonamide compounds such as 2-[[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]aminosulfonyl]-N,N-dimethyl benzeneethanesulfonamide and 2-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]aminosulfonyl]-N, N-dimethylbenzeneethanesulfonamide, agricultural compositions containing them and their herbicidal utility are disclosed.
