Introduction: Hexamethyldisiloxane (silicone ether, MM sealing agent) is a colorless and transparent liquid that is prone to deliquescence. Insoluble in water, soluble in various organic solvents. Used as silicone oil, silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, etc. Obtained by hydrolysis of trimethylchlorosilane. The physical properties of hexamethyldisiloxane colorless and transparent liquids. Easily deliquescent, flammable, and in contact with high heat, open flames, and strong oxidizing agents, there is a risk of combustion. Boiling point 99.5 ℃. Flash point -1.1 ℃. Relative density (d2525) 0.7606. The refractive index is 1.3750. Insoluble in water, soluble in various organic solvents. Hexamethyldisiloxane is an important primary organic silicon raw material, often used as a capping agent in the production of silicone oil, or as a cleaning agent for silicone rubber, pharmaceuticals, gas c...

Glufosinate-ammonium is a broad-spectrum contact-killing herbicide successfully developed by the former German company Egfor in the 1980s. Plants die. Glufosinate-ammonium has the characteristics of broad herbicidal spectrum, low toxicity, high activity and good environmental compatibility, and is sensitive to most glyphosate-resistant weeds, and has broad application prospects.
Huaxing Chemical is a high-end, high-content glufosinate-ammonium preparation brand developed by Huaxing Chemical after years of technological innovation, research and development and promotion.
One: glufosinate-ammonium application advantages:
As a biocidal herbicide, glufosinate-ammonium has many advantages, mainly in three aspects. First, it is relatively safe for crop roots, and will not harm crops with shallow roots. It is safe to spray between crops and can be used on all wide-row high-stem crops, including bananas, grapes, seedlings, pear trees, peach trees, Citrus, corn, etc.; secondly, the control effect of glyphosate and paraquat-resistant goosegrass and P. chinensis is more obvious; thirdly, the weeding speed is significantly faster than that of glyphosate.
Two: Analysis of mainstream glufosinate-ammonium on the market:
At present, the mainstream glufosinate-ammonium on the market has two types of three contents, the three contents are 10%, 200 g/L and 30% respectively; the two types are mainly one is pure refined powder formula, the other is pure mother liquor formula . The low content is mainly based on the mother liquor formula, and the high content is mainly based on the refined powder formula, such as Huaxing's Blitz.
In addition to the large price difference between the two formulas, the weeding thoroughness and the weed control time are also different. Generally, the grass control time of the refined powder formula can reach 40-45 days, while the mother liquor formula is generally within 30 days.
In addition, the refined powder formula has little impact on the microorganisms in the soil and will not cause soil compaction, while the pure mother liquor has a certain amount of heavy metal ions due to high impurities, which has a certain degree of damage to the soil, and the safety of shallow root crops is not as good as the refined powder formulation.
Three: The herbicidal spectrum of glufosinate-ammonium:
The herbicidal spectrum of glufosinate-ammonium is very broad, and most of the annual or perennial grass weeds and broad-leaved weeds can be well controlled, such as beef tendon grass, small fly, goldenrod, bluegrass, foxtail, crabgrass , bermudagrass, barnyardgrass, humulus japonicus, fenugreek, purslane, iron amaranth, anti-branch amaranth, hollow lotus seed grass, chickweed, mother-in-law, field bindweed, polygonum, shepherd's purse, endive vegetable, fly leech, thorn Children's dishes and so on. In particular, the control effect of glyphosate against glyphosate is better.
