Glyphosate is a non-selective, non-residual herbicide that is very effective against perennial root weeds. It is widely used in rubber, mulberry, tea, orchards and sugarcane fields. Due to the different sensitivity of various weeds to glyphosate, the dosage is also different. 1. Weeding in orchards, mulberry orchards, etc. Use 0.5-1 kg of 10% aqua per mu for the control of 1-year-old weeds, and 1-1.5 kg of 10% aqua per mu for the control of perennial weeds. Mix 20-30 kg of water to spray the stems and leaves of weeds. 2. Farmland weeding: Prevent and control the weeds that have grown in the field before planting the stubble. The dosage can refer to the orchard for weeding. In the cotton growing period, a directional spray with a hood is required. Use 0.5-0.75 kg of 10% aqua per mu and add 20-30 kg of water. 3. Weeding in fallows, fields, and roadsides. At the 4-6 leaf stage of weeds, use 0.5-1 kg of 10% water solution per mu, add 100 ml of diesel oil, add 20-30 kg of water, and spray the weeds. 4. For some malignant weeds, such as Cyperus rotundus, 200 grams per mu of land can be added with adjuvants, the effect of weeding is good.
