Abstract
The invention relates to a glyphosate water-based composition. The glyphosate water-based composition is characterized in that: the weight percentage of the glyphosate (based on glyphosate acid) in the composition is more than or equal to 20 percent; and the weight percentage of sulfate ions or hydrogen sulfate ions is more than or equal to 20 percent. The glyphosate water-based composition can be processed into an aqueous agent and a suspending agent. The composition has the advantages of promoting plants to adsorb and transmit the glyphosate, enhancing the herbicidal activity of the glyphosate, reducing the using amount of the glyphosate and having special effect of weeding noxious weed such as cogongrass, alligator alternanthera, scandent hop and the like.
Description
Technical field
The present invention relates to a kind of herbicidal composition, particularly relate to glyphosate water-based composition and preparation thereof.
Background technology
Glyphosate (glyphosate), formal name used at school N-((phosphonomethyl)) glycine, N-((phosphonomethyl)) amion acetic acid (Phosphonomethyl Imino Acetic Acid) is a kind of organophosphorus herbicide.Glyphosate absorbs by plant leaf blade and non-woody stem as non-selective, noresidue herbicide after seedling, conducts to the plant corpus each several part, and is very effective to dark root perennial weed and annual and biennial grass family, sedge family and broad leaved weed.The most outstanding characteristics of glyphosate are in can being conducted to underground rhizome downwards and be tillered by the cauline leaf absorption, and are extremely strong to weeds underground organization destructive power.In China, glyphosate is used widely, is the weed killer herbicide of China's usage amount maximum.Yet, glyphosate in use, the medicament availability is low, fails to obtain due control efficiency as a rule.Agricultural chemicals in developed country annual nearly 25% is wasted because of improper use, in China then up to 60%.The bioavailability that how to improve pesticidal preparations is most important to agricultural sustainable development.
Studies show that in a large number ammonium sulfate can play synergistic effect to the activity of weeding of glyphosate.Its main mechanism be can eliminate spray in the water, on the plant stem-leaf and even the cations such as Ca2+, Mg2+ that exist in inside plants tissue and the glandular secretion thing antagonism that glyphosate is played, sulfate radical wherein can be combined into water-soluble little calcium sulphate with cations such as Ca2+, Mg2+, magnesium sulfate is separated out.Simultaneously, the transporting in weeds has significant facilitation to ammonium sulfate to glyphosate.
But because the solvability of ammonium sulfate in water is limited, the amount of adding ammonium sulfate in the glyphosate more than 30% (in the glyphosate) waterborne preparation is smaller or equal to 15%, and the easy crystallization of formulation products.The ammonium sulfate concentrations that can add in the disclosed glyphosate formulation of Chinese invention patent application CN1649494 is up to 180g/L.After yet 15% ammonium sulfate diluted 150 times in use, concentration had only one thousandth, and synergistic effect is limited.Up to the present, also do not have sulfate ion or hydrogen sulfate ion content more than or equal to 20% water baseization glyphosate formulation research report, do not contain sulfate radical or bisulfate ion compound research report yet as the glyphosate synergist about beyond the ammonium sulfate all the other.
Summary of the invention
The objective of the invention is to strengthen absorption and the availability of weeds, improve preventive effect glyphosate in order to improve the concentration of sulfate ion in the glyphosate waterborne preparation or hydrogen sulfate ion.The researcher has carried out in the high content glyphosate preparation research of adding multiple inorganic and organic amine salt, and finds first: the other forms of sulfate ion except that ammonium sulfate or its synergistic effect of hydrogen sulfate ion of adding in the high content glyphosate preparation 20% or more are compared better with interpolation 15% ammonium sulfate.Main performance comprises that resistance to hard water strengthens, and what glyphosate absorbed and conducted in weeds speeds up, and activity of weeding strengthens, and preparation is more stable.Through a large amount of prescription screenings, successful has developed glyphosate (in glyphosate) content more than or equal to 20%, sulfate ion or hydrogen sulfate ion content is more than or equal to 20%, and cloud point is more than or equal to 50 ℃, and crystalline temperature is smaller or equal to 0 ℃ stable aqua and stable suspersion agent.
When composition was aqua, its prescription consisted of:
Glyphosate or salt (in glyphosate) 20%---50%
Sulfate ion or hydrogen sulfate ion 20%---50%
Surfactant 7%---15%
Water surplus
Wherein surfactant is one or more in benzylphenol APEO, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, alkyl glycoside, tallow amine ethyl group thing, Tea Saponin, cocoa butter amide compound, the organosilicon.
When composition was suspending agent, its prescription consisted of:
Glyphosate 20%---50%
Sulfate ion or hydrogen sulfate ion 20%---50%
Surfactant 3%---10%
Antifreeze 2%---3%
Thickener 1%---2%
Defoamer 0.1%
Water surplus
Wherein: surfactant is one or more in JFC, agricultural newborn 603#, agricultural newborn 600#, alkylphenol polyoxyethylene or its phosphate, fatty alcohol-polyoxyethylene ether, lignosulfonates, the naphthalenesulfonate formaldehyde condensation compound; Antifreeze is an ethylene glycol; Thickener is an xanthans; Defoamer is a silicone.
With the agent of existing glyphosate list or the glyphosate formulation that adds ammonium sulfate mutually this, the present invention has following advantage:
1. weeds improve 10% to absorption, the conductive quantity of glyphosate---and 30%
2. resistance to hard water strengthens, and in 342ppm hard water, synergy is obvious.
3. preparation stability is higher, with the glyphosate formulation that adds ammonium sulfate mutually this sulfate ion content improved 50%---260%.
4. reduce consumption 10%---30%, the usage amount of saving agricultural chemicals has reduced the pollution to environment.
