Tribenuron-methyl, a sulfonylurea herbicide categorized as an acetolactate synthase (ALS) inhibitor, is employed to manage specific broadleaf weeds in cereal and grass crops. Its application extends to non-crop areas and turfgrass. Operating as a systemic herbicide, tribenuron-methyl is absorbed by plants and transported through their vascular systems. Within scientific research, tribenuron-methyl serves as useful for investigating the impact of ALS inhibitors on plant growth and development. It finds use in genetic engineering studies, where the effects of herbicides on gene expression are explored. Additionally, tribenuron-methyl has been employed in studies examining the influence of herbicides on soil microbial communities. The mode of action of tribenuron-methyl involves the inhibition of the enzyme acetolactate synthase (ALS), a vital component in the synthesis of branched-chain amino acids within plants. Through this inhibition, branched-chain amino acids accumulate within the plant, ultimately resulting in its demise.
