Usage

General Description

Sulfometuron is a selective herbicide commonly used to control a wide range of grasses and broadleaf weeds in various agricultural and non-crop areas. It belongs to the chemical class of sulfonylurea herbicides and works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for the biosynthesis of branched-chain amino acids in plants. As a result, the affected plants stop growing and eventually die. Sulfometuron is known for its long-lasting residual activity and low application rates, making it an effective and economical choice for weed control. However, it should be used with caution as it has the potential for leaching into groundwater and posing risks to non-target plants and animals. Therefore, proper application practices and adherence to label instructions are necessary for safe and effective use of sulfometuron.

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.

Agricultural sulfonamides

N-(heterocyclicaminocarbonyl)arylsulfonamides in which the aryl radical is substituted in the 2-position by a carboxy radical, ester, thioester, or amide thereof; e.g. N-[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide or N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide; are useful for the regulation of plant growth and as pre-emergence and post-emergence herbicides.
