Metsulfuron-methyl is a systemic herbicide commonly used to control a broad spectrum of weeds in various crops, pastures, and non-crop areas. It inhibits the production of branched-chain amino acids in susceptible plants, disrupting their growth and ultimately leading to their death.
Metsulfuron-methyl is valued for its effectiveness at low application rates, long-lasting residual activity, and selective action against broadleaf weeds while being relatively safe for grasses.
However, it requires careful application to avoid damage to desirable vegetation and minimize the risk of environmental contamination.
Adherence to label instructions and stewardship practices is essential for maximizing the efficacy and safety of metsulfuron-methyl.
