Bensulfuron-methyl

Description:
Bensulfuron-methyl is a selective herbicide primarily used for controlling broadleaf weeds and certain grasses in various crops, particularly rice. It belongs to the sulfonylurea class of herbicides, which function by inhibiting the enzyme acetolactate synthase (ALS), crucial for amino acid synthesis in plants. This compound is characterized by its high efficacy at low application rates, making it an environmentally favorable option compared to traditional herbicides. Bensulfuron-methyl is typically applied pre-emergence or post-emergence, depending on the target weeds and crop type. It is moderately soluble in water and has a relatively low volatility, which helps minimize the risk of off-target effects. The substance is also known for its residual activity in the soil, which can influence subsequent crops if not managed properly. Safety data indicates that, while it poses some risks to aquatic organisms, it is generally considered to have a low toxicity profile for humans and non-target species when used according to label instructions.
