Glyphosate is an organophosphorus herbicide. It is a non-selective systemic conductive herbicide for stem and leaf treatment. It was developed by Monsanto in the early 1970s. It is usually made into isopropylamine or sodium salt when used. Its isopropylamine salt is the active ingredient of the well-known herbicide trademark “Roundup”. Glyphosate is a highly effective, low-toxic, broad-spectrum herbicide with a systemic conduction effect. This product dissolves the waxy layer on the surface of the leaves, branches and stems of the weeds, and the medicinal effect quickly enters the plant conduction system to produce an effect, causing the weeds to dry up and die. It can effectively control annual and biennial grasses, cyperaceae and broadleaf weeds. It has a good control effect on perennial weeds such as thatch, cyperus rotundus and bermudagrass. It is widely used in orchards, mulberry gardens, tea gardens, and rubber Chemical weeding of gardens, grassland renewal, forest fire lanes, railways, highways, wasteland and no-till land.
Glyphosate pesticide dosage:
1. For weeding in orchards, mulberry gardens, etc., use 0.5-1 kg of 10% aqua per mu for weed control and 1-1.5 kg per mu of perennial weeds. Spray 20-30 kg of water and spray the stems and leaves of weeds.
2. Weeding in the farmland before planting the stubble in the farmland, prevent and control the weeds that have grown in the field before sowing. 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 20-30 kg of water.
3. Weeding at the 4-6 leaf stage of weeds in fallow land, field and roadside, use 0.5-1 kg of 10% aqueous solution per mu, add 100 ml of diesel oil, 20-30 kg of water, and spray weeds.
Glyphosate is a kind of biocidal herbicide, if used improperly, it will bring safety hazards to crops. Some farmers use glyphosate to weed the ridges, often because of the dispersion of glyphosate, causing phytotoxicity to nearby crops. There are also farmers who fail to clean the sprayer as required after using it. As a result, when spraying other pesticides, the residual glyphosate is sprayed on other crops, causing phytotoxicity. If phytotoxicity occurs on rice, the leaves will become chlorosis in the lighter ones, causing serious growth obstacles, and the severe ones may die early, or fail to head or deformed ears, which will cause losses to rice production.
