In the wheat field with more lacquer (Pentaphorus), mother-in-law, and barnyardgrass, the application of a mixture of Astragalus, 20% of which can increase its dosage to 35-40 ml per mu.
To see cornfields such as Acacia, Japanese Acacia, Hardgrass, and Wild Oats, etc., use 6.9% of the 6.95% PUMA oil per acre, or 10% of a 75 to 100 mL of a Chinese herb, or 25% Isoproturon 300-350g must be applied from mid-late February to early March.
