Certain N-[(heterocyclic)aminocarbonyl]thiazolesulfonamides, such as N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-4-thiazolesulfonamide, are useful as herbicides and/or plant growth regulants.

Herbicidal thiazole derivatives

Thiazole derivatives

The invention relates to certain pyridine sulfonamide compounds having haloalkenyl substituents ortho to the sulfonylurea linkage.

Herbicidal sulfonamides

This invention relates to certain sulfonylurea compounds having substituents ortho to the sulfonyl-urea linkage that includes a 3- or 4-membered carbocyclic ring, a saturated 5- or 6-membered carbocyclic ring of a heterocyclic ring which contains 1 hetero-atom selected from O, S and NR.sub.3, agriculturally suitable compositions thereof and a method of their use as herbicides or plant growth regulants.

The invention relates to certain sulfonamide compounds having substituents ortho to the sulfonylurea linkage, said substituents including alkenyl, substituted alkenyl, cycloalkenyl, substituted cycloalkenyl, alkynyl and substituted alkynyl.

The invention relates to certain pyrazole sulfonamide compounds having haloalkenyl substituents ortho to the sulfonylurea linkage.

The invention relates to certain thiophene sulfonamide compounds having alkenyl substituents ortho to the sulfonylurea linkage.

This invention relates to novel disubstituted benzylsulfonamides and benzenesulfamates, agriculturally suitable compositions thereof and a method of their use as preemergent or postemergent herbicides or plant growth regulants.

Herbicidal 2,6-disubstituted benzylsulfonamides and benzebesulfamates

This invention relates to certain sulfonylurea compounds having substituents ortho to the sulfonylurea linkage that includes a 3- or 4- membered carbocyclic ring, a saturated 5- or 6- membered carbocyclic ring or a heterocyclic ring which contains 1 heteroatom selected from O, S and NR.sub.3, agriculturally suitable compositions thereof and a method of their use as herbicides or plant growth regulants.

Sulfonylurea compounds which contain dihydroisobenzofuran, dihydroisobenzothiophene, or isoindoline 4-sulfonamide substituents such as 1,3-dihydro-N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]benzo[c] furan-4-sulfonamide and their use as agricultural chemicals, including plant growth regulants and herbicides.
