Abstract
The present invention discloses a soluble solid glyphosate preparation which comprises a glyphosate ingredient. The present invention is different from the prior art that the glyphosate ingredient adopts the glyphosate raw powder, and is added with a surface active agent and a synergism solubilization additive; the glyphosate raw powder and the surface active agent respectively accounts for 20% to 70% and 4 to 12% of the total amount, and the synergism solubilization additive is the rest amount. The present invention has the advantages of little environment pollution, low cost, cheap selling price, easy transportation, package and storage and convenient carrying and use.
Description
The weed killer herbicide that the present invention relates to use on the agricultural is a kind of steriland herbicide, specifically, be a kind of be the water-soluble solid dosage forms of Main Ingredients and Appearance with the glyphosate technicals.
Glyphosate is all bigger unique steriland herbicide of China's output and consumption, domestic large tracts of land be used for mulberry, really, tea place and uncultivated area weeding, the export volume of glyphosate technicals is also bigger, is the main pesticide species of China's foreign exchange earning.But because glyphosate can not be water-soluble, prior preparation method mainly is to add isopropylamine etc. to dissolve to form glyphosate isopropyl amine salt etc., so that its final water soluble forms aqua.As U.S. broad-mouthed receptacle for holding liquid mountain all " farming reaches " board 41% glyphosate isopropyl amine salt aqua of company exploitation, the weed killer herbicide that China generally uses, effect is best at present exactly.China is because the auxiliary agent problem that adopts, the similar products of being produced on drug effect " farming reaches " for poor, therefore, the domestic market has been full of U.S.'s " farming reaches " 41% glyphosate isopropyl amine salt aqua weed killer herbicide, and this product is actually and utilizes the auxiliary agent that adds the U.S. after former powder of glyphosate that China produces and the isopropylamine dissolving to produce, therefore, how to utilize homemade auxiliary agent to produce highy potent herbicide and become the important topic of pendulum in face of China's pesticide producing industry.
The purpose of this invention is to provide a kind of good drug efficacy, cost low, pollute less, glyphosate soluble solids formulation easy to use.
Technical solution of the present invention is: a kind of soluble solid glyphosate preparation, contain the glyphosate composition, and the difference of itself and prior art is: what the glyphosate composition adopted is the former powder of glyphosate, and with addition of surfactant and synergy solubilising additive are arranged; The former powder of glyphosate, surfactant shared proportion in total amount is respectively 20%-70%, 4-12%, and all the other are synergy solubilising additive.
What the surfactant described in the present invention adopted is natural non-ionic surface active agent, or cationic surfactant, anion surfactant etc.
Non-ionic surface active agent described in the present invention adopts commercially available SDP (being natural non-ionic additive).
Certainly, also can adopt other proper auxiliary agent etc.
Synergy solubilising additive described in the present invention comprises synergy solubilizer and filler.Certainly, also can adopt other suitable component forms.
The prescription of the product described in the present invention is: the glyphosate 30-60% of purity more than 95%; SDP5-10%; Sulfuric acid amine 8-20%; Urea 10-30%; All the other are filler.Certainly, also can adopt other suitable prescription forms.As adopt other synergy solubilizer or single synergy solubilizer etc.
The concrete prescription of the product described in the present invention is: 95% glyphosate 30% (or other suitable purities or ratio); SDP7%; Sulfuric acid amine 10%; Urea 20%; All the other are the filler glauber salt.Certainly, also can adopt other suitable concrete prescriptions.As adopt suitable synergy to increase flux, and other suitable fillers etc.
The concrete prescription of the product described in the present invention also can be: 95% glyphosate 40% (or other suitable purities or ratio); SDP10% (or other suitable zwitterion auxiliary agents); Sulfuric acid amine 10%; Urea 30%; All the other are glauber salt.Certainly, also can adopt other suitable concrete prescription and proportionings.
The concrete prescription of the product described in the present invention also can be: 95% glyphosate 50%; SDP10%; Sulfuric acid amine 15%; Urea 20%; All the other are glauber salt etc.Certainly, also can adopt other suitable concrete prescription or proportionings.As adopt four kinds or six kinds or more kinds of components etc.
The concrete prescription of the product described in the present invention also can be: 95% glyphosate 20%; SDP9%; Sulfuric acid amine 15%; Urea 25%; All the other are glauber salt etc.Certainly, also can adopt other suitable concrete prescription or proportionings.As adopt other suitable fillers, other suitable auxiliary agents etc.
The form of the product described in the present invention is powdery or sheet, bulk and graininess etc.Certainly, also can adopt other suitable solid dosages.
Advantage of the present invention is: good drug efficacy, drug effect surpasses the existing world, domestic weed killer herbicide product with glyphosate content.Environmental pollution is few, cost is low, price is cheap, be easy to transportation, packing and store, be convenient for carrying and use.The present invention is owing to add surfactant, particularly after the nonionic natural agents, ruined hydroxyl obtains repairing, replenishing after making glyphosate become aqua with other dissolution with solvents, the diffusion of surfactant simultaneously, help and synergistic effect such as ooze, so its drug effect is increased, restrain in the dosage process range with 100-300 at mu as the solvable pulvis of 30% glyphosate, preventive effect to all kinds of weeds, particularly perennial weed slightly is better than or significantly is better than the effect that U.S.'s farming reaches the processing of 41% glyphosate isopropyl amine salt aqua.And overcome the existing aqua product cost height intrinsic, used shortcomings such as inconvenience at aspects such as transportation, packing, storages.Can directly drop into the i.e. all dissolvings of stirring a little through several minutes in the water, and not have precipitation.Advantage of the present invention also can be by table 1: " 30% glyphosate soluble powder and farming reach aqua herbicidal effect relatively (behind the medicine 5-15 days) ", and table 2: " 30% glyphosate soluble powder and farming reach aqua herbicidal effect relatively (behind the medicine 25 days) ", table 3: " weeds cover degree * and plant height before the dispenser ", table 4: " 14 days weeds preventive effects after the dispenser ", table 5: " 28 days weeds preventive effects after the dispenser " waits and is illustrated.
Below in conjunction with embodiment the present invention is described in further detail:
Example 1:
Prescription: the former powder 30% of 95% glyphosate;
SDP (Nantong FeiTian Chemical Industry Co.,Ltd's production and sales) 7%;
Sulfuric acid amine 10%;
Urea 20%;
All the other are the filler glauber salt.
Earlier the former powder of glyphosate is crushed to 80-100 day (or other appropriate particle size); then with former powder and synergy solubilizer (sulfuric acid amine, urea), fill chaste tree etc. by prescription stir pulvis; certainly; also can again pulvis be pressed into sheet, piece agent through forming machine; or in comminutor, be molded into the graininess formulation again, with convenient storage, transportation and packing, use.
Example 2:
Prescription: 95% glyphosate 40%;
SDP10％；
Sulfuric acid amine 10%;
Urea 30%;
All the other are glauber salt or other suitable fillers.
The same substantially precedent of preparation method, or adopt other suitable agricultural chemicals mixing manufacture methods.
Example 3:
Prescription: the former powder 50% of 95% glyphosate;
SDP10％；
Sulfuric acid amine 15%;
Urea 20%;
All the other are glauber salt.
The same substantially precedent of preparation method.
Example 4:
Prescription: 95% glyphosate 20%;
SDP9％；
