Abstract
The invention belongs to the technical field of pesticide and relates to a water-soluble paste agent containing paraquat dichloride. The water-soluble paste agent comprises 0.5-45% of paraquat dichloride amounting to 0.362-32.58% of paraquat cation, 5-40% of surfactant, safe auxiliary components of emetic, warning coloration, stink agent and bitter agent, etc. and the balance of water. According to the invention, paraquat is processed into a paste agent, which can effectively avoid human or animal skin calcination caused by splashing of paraquat preparation; because the water-soluble paste agent has low fluidity, accidental taking or impulse swallow is reduced, and safety of the paraquat is enhanced substantially.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of water-soluble paste containing paraquat two villaumites.
Technical background
Paraquat (paraquat), is the bipyridyliums steriland herbicide of quick-acting contact killing types, is one of current global most widely used weed killer herbicide product, and global marketing and usage amount are only second to glyphosate, occupy the 2nd large weed killer herbicide product.But, because paraquat has stronger acute toxicity to people or other mammals, and the medicament that effectively do not detoxify, therefore, once wrongly take or have a mind to the paraquat of swallowing, not obtaining in time, under correct rescue, can cause serious injury to human or animal, even can therefore get killed.
In order to improve the safety of paraquat, especially the safety to the mankind, in international food and agricultural organization regulation paraquat preparation, must add emetic---three kinds of safe adjuvants such as triazole pyrimidone, stink agent and warning colouration, to reduce the rate of wrongly taking of paraquat, and then the safety that improves paraquat.But along with being widely used of paraquat, the event of paraquat poisoning or skin contact burn constantly occurs, to such an extent as to paraquat is forbidden or limited the use of in the countries such as European Union.Local farmers is had to, and alternative costs are higher, speed of action is slower other weed killer herbicides carry out weed control, have even recovered consumption rate the most consuming time, artificial weeding operation that production efficiency is low.Greatly fettered the development process of modern agriculture, especially for developing country originally backward in economy, be undoubtedly a kind of huge economy and hit.
Therefore, at paraquat Rapid Popularization, use, vast farmers is more and more favored, simultaneously, various places non-government organization appeals to improve under the environment such as paraquat safety and trend strongly, develop and a kind ofly can significantly reduce the injury of paraquat to human or animal, the safety new formulation that improves paraquat preparation is particularly necessary.
Summary of the invention
The object of the invention is the above-mentioned deficiency for prior art, a kind of water-soluble paste containing paraquat two villaumites.
Object of the present invention can be achieved through the following technical solutions:
Containing a water-soluble paste for paraquat two villaumites, paraquat two villaumites that are 0.5-45% containing quality percentage composition, amounting to paraquat cation quality percentage composition is 0.362-32.58%.
Paraquat two villaumites that should be preferably 5-42% containing quality percentage composition containing the water-soluble paste of paraquat two villaumites, amounting to paraquat cation quality percentage composition is 3.62-30%.
This water-soluble paste also comprises the surfactant that quality percentage composition is 5-40%, preferably comprises the surfactant that quality percentage composition is 5-15%.
Described surfactant is selected from any 1～4 kind in neopelex, lauryl sulfate, sodium sulfate of polyethenoxy ether of fatty alcohol, alcohol ether succinate sodium sulfonate, fatty acid sulfoalkyl acid amides, fatty alcohol-polyoxyethylene ether AEO-9, tallow amine APEO (n=2), castor oil polyoxyethylene ether EL-40, alkyl phenol formaldehyde resin polyoxyethylene ether, lauroylamidopropyl betaine, cocamidopropyl betaine.
It is that the triazole pyrimidone of 0.001-1% is as emetic that this water-soluble paste contains quality percentage composition.
It is that the acid blue 9 of 0.01-1% is number as warning colouration that this water-soluble paste contains quality percentage composition.
This water-soluble paste contains benzene first DEXAMETHASONE SODIUM PHOSPHATE ammonium that quality percentage composition is 0.0001-0.1% or at least one material in saccharin benzylamine amide as bitters.
This water-soluble paste is also containing frowziness agent and water.
It is that 0.1% pyridine is as stink agent that this water-soluble paste contains quality percentage composition.
A kind of typical processing method of water-soluble paste containing paraquat two villaumites is: 1, the aqueous solution containing paraquat is mixed with a certain proportion of stink agent and pH adjusting agent, stir; 2, add bitters, emetic and warning colouration, stir; 3, add surfactant, and at the evenly rear blowing of 50-60 ℃ of insulated and stirred; 4, material is cooled to after room temperature, and forms the ointment preparation of high viscosity, lazy flow---water-soluble paste.
Beneficial effect of the present invention:
The present invention is processed into paste by paraquat, the skin of the calcination mankind or animal that not only can effective less paraquat preparation splashes, and can be low because of mobility of the present invention, wrongly take or the impulsion property amount of swallowing low, and significantly improve the safety of paraquat.
The present invention introduces bitters, makes the paraquat paste of bad hypopharynx originally, and because strange suffering is when more swallowing, therefore, the safety of paraquat paste further improves.
Aspect processing, water-soluble paste thing of the present invention, outside all components that comprises conventional paraquat preparation, only increased bitters, do not contained the water-insoluble matter such as thickener and solid packing, processing method is identical with paraquat aqua with production equipment, can share a covering device with paraquat aqua, therefore, do not have the needs of newly added equipment, production cost can not improve.
In use, the present invention has excellent water-soluble and instant capacity, flexible and convenient to use, can not bring unnecessary trouble to user, and its result of use is no less than paraquat aqua.
Specific implementation method
The processing method that contains the water-soluble paste of paraquat two villaumites in following examples is: 1, the aqueous solution containing paraquat is mixed with a certain proportion of stink agent and pH adjusting agent, stir; 2, add bitters, emetic and warning colouration, stir; 3, add surfactant, and at the evenly rear blowing of 50-60 ℃ of insulated and stirred; 4, material is cooled to after room temperature, and forms the ointment preparation of high viscosity, lazy flow---water-soluble paste.
