Introduction of 74223-64-6 :

Metsulfuron-methyl is a systemic sulfonylurea herbicide that has been widely used to control broadleaf weeds and annual grasses in rice, corn, wheat, and barley. Metsulfuron-methyl exhibits high herbicidal activity and low mammalian toxicity, with an LD50 for rats exceeding 5000 mg/kg[1][2][3]. In Vivo:Metsulfuron-methyl (0.045 or 0.45 g a.i./ha, spraying, speed of 1 m/s, delivering 0.02 L/m2, with reference to the control group’s maturation time) effectively inhibits the growth and reproduction of five plants (including monocots and dicots, terrestrial and aquatic species: Mimulus ringens, Bidens cernua, Sinapis arvensis, Phaseolus vulgaris, and Echinochloa crusgalli), and the most effective herbicidal control was observed during the seed stage[2].
Note: g a.i./ha indicates the number of grams of active ingredient applied per hectare of land.
