Soil treatment before sowing: For some turf live field and high-density grazing direct weeds (such as rice leeks), the 10% glyphosate soluble liquid is 500ml per mu. Or use 125% of the 41% nutrient soluble liquid agent, or 150ml of 50% gram of traceable soluble liquid agent, spray evenly on the rice about 7 days before sowing, and eliminate the weeds.

Post-emergence treatment: rice 2 leaves to 3 leaf stage, with 36% dichloro-benzyl WP WP 30g ~ 50g, spray 40kg of water on stems and leaves to control valerian, sedge, broadleaf grass.
