- 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.

- Synthesis of 1,2,4-Triazolopyrimidine-2-sulfonamides
-
The 1,2,4-triazolopyrimidine-2-sulfonamides are a new class of highly active herbicides.A novel cyclization method for the synthesis of these compounds is discussed.

- Substituted 1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamides, compositions containing them, and their utility as herbicides
-
Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonamides, e.g., 5,7-dimethyl-N-(2,6-dichlorophenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide and their agriculturally acceptable salts are prepared. These compounds and compositions containing them are useful for the control of unwanted vegetation. Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonyl chlorides and substituted anilines and their use as intermediates are also described.
