Sulfometuron-methyl

Description:
Sulfometuron-methyl is a selective herbicide primarily used for controlling annual and perennial weeds in various agricultural settings, particularly in crops like soybeans and corn. It belongs to the sulfonylurea class of herbicides, which function by inhibiting the enzyme acetolactate synthase (ALS), crucial for the synthesis of branched-chain amino acids in plants. This inhibition leads to the cessation of growth and eventual death of the targeted weeds. Sulfometuron-methyl is characterized by its systemic action, allowing it to be absorbed through both foliage and roots. It is typically applied pre-emergence or post-emergence, depending on the specific weed management strategy. The compound is moderately soluble in water and has a relatively low volatility, which helps minimize the risk of drift during application. Environmental persistence can vary, but it is generally considered to have a moderate half-life in soil. Safety measures should be observed during handling, as it can pose risks to non-target plants and aquatic organisms if misapplied.
