Usage

Definition

ChEBI: An N-sulfonylurea in which the sulfur atom is attached to a 2-carboxythiophen-3-yl group and in which the non-sulfonated nitrogen is substituted by a 4-methoxy-6-methyl-1,3,5-triazin-2-yl group. The corresponding methyl ester, known as t ifensulfuron-methyl, is used as a post-emergence herbicide for the control of grass and broad-leaved weeds.

HERBICIDAL COMPOSITIONS

The present invention provides compositions comprising herbicidally active compounds (A) and (B), where (A) represents one or more compounds of the general formula (I) or agrochemically compatible salts thereof [component (A)], and (B) represents one or more herbicides [component (B)]. The application further relates to a method and to the use of the herbicidal composition according to the invention for controlling harmful plants or for regulating growth.

Herbicidal compositions with increased crop safety

Disclosed are herbicidal concentrate formulation compositions having reduced grass crop plant phytotoxicity comprising certain sulfonamide or sulfonylurea herbicides in admixture with a non-herbicidal organic or inorganic acid or mixture thereof in an amount sufficient to insure that during the post-emergent agricultural uses thereof in water diluted form the pH of the mixture is below about 5; also disclosed is the preparation of said compositions, aqueous formulations of said concentrate and the use of said formulations.

Herbicidal heterocyclic sulfonylurea compositions safened by herbicidal acids such as 2,4-D below a pH of 5

Disclosed are herbicidal concentrate formulation compositions having reduced grass crop plant phytotoxicity comprising certain sulfonamide or sulfonylurea herbicides in admixture with a herbicidal organic acid from the group consisting of clopyralid, 2,4-D, 2,4-DP, dicamba, dichlorprop-P, fluroxypyr MCPA, MCPP, mecoprop-P, picloram, triclopyr or mixtures of said acids; also disclosed is the preparation of said compositions and the pre- and post-emergent agricultural uses thereof in water diluted form.
