MCPA-sodium is a selective endogenous transduction hormone herbicide of phenoxyacetic acid, which can damage the conduction tissues of dicotyledonous plants, interfere with the growth and development, distort the stem and leaf, expand and thicken the stem base or crack.The volatility and action rate were lower and slower than 2, 4-d. MCPA-sodium was very sensitive to the seedling stage of gramineous plants, and the resistance gradually increased after the 3-4 leaf stage, the highest at the end of tiller stage, and the sensitivity increased again at the stage of young panicle differentiation.When the temperature is lower than 18℃, the effect is obviously worse, which is not good for unexcavated weeds.Usually 30 to 60 grams per acre (active ingredient).Strictly prohibited for dicotyledon crops!

Glyphosate is a non-selective, residue-free herbicide that is very effective against perennial rooting weeds and is widely used in rubber, mulberry, tea, orchards and sugar cane fields.Mainly inhibit the enol acetone-shikimin phosphate synthetase in plants, so as to inhibit the conversion of shikimin to phenylalanine, tyrosine and tryptophan, so that the protein synthesis is interfered, leading to the death of plants.Glyphosate is absorbed by the stems and leaves and then transmitted to various parts of the plant, which can prevent monocotyledons and dicotyledons, annuals and perennials, herbs and shrubs, and more than 40 families of plants.Glyphosate is inactivated by the combination of iron, aluminum and other metal ions soon after burial, and has no adverse effect on seeds and soil microorganisms hidden in the soil.
