Abstract
The invention discloses a pesticide composition containing a herbicide paraquat, namely a paraquat water-soluble gel and a preparation method thereof. The paraquat water-soluble gel consists of the following raw materials in percentage by mass: 0.1 to 30.0 percent of paraquat cations, 0.1 to 1.0 percent of emetic, 0 to 0.5 percent of odorizer, 1.0 to 90.0 percent of thickening synergistic agent and the balance of water. The preparation method comprises the following steps of: uniformly shear-mixing the water, the emetic, the odorizer and the thickening synergistic agent at the temperature of between 10 and 100 DEG C, adding paraquat mother liquor, and shear-mixing uniformly to obtain the paraquat water-soluble gel. In the preparation, the liquid or paste synergistic agent can be conveniently added according to the formula, and the pollution of toxic dust caused when the paraquat is prepared into a solid preparation is also avoided. In addition, the preparation is a colloidal substance, so the disadvantage that paraquat aqueous solution is easy to orally take is overcome; and the pesticide composition has good social and economic benefits.
Description
Technical field
The present invention relates to a kind of composition pesticide that contains herbicides paraquat and preparation method thereof, but be specifically related to a kind of paraquat glue and preparation method thereof.
Background technology
Paraquat (chemical name is 1,1 '-dimethyl-4,4 '-bipyridine cation salt) be the second largest weed killer herbicide that is only second to glyphosate, be a kind of quick-acting contact killing type steriland herbicide.Paraquat all has very strong destruction to the chlorenchyma of unifacial leaf and dicotyledon, but does not have conduction, and the medicine position is injured, and can not damage seed hiding in plant root and the soil.Once with after soil contacts, promptly be adsorbed the passivation inactivation.At present, paraquat formulation product is mainly 20%, 25% aqua, and standard GB 19308-2003 " paraquat aqua " has done detailed regulation to it.
Zoopery shows that paraquat belongs to medium malicious class, and rat oral LD50 dichloride is 155～203mg/kg, and two Methylsulfate salt are 320mg/kg.But it is very high to people's toxicity, and the adult estimates that lethal dose 20% aqueous solution is about about 5～15mL or 40mg/kg.It is the highest weed killer herbicide of human acute poisoning lethality, medically so far not to effective methods of treatment of paraquat poisoning and medicine, reported that abroad death reaches hundreds of examples, many per os are wrongly taken deadly, and it is all dead wherein to wrongly take 49 above examples of 20% paraquat aqua 30mL.Domestic oneself has many acute poisoning case reports, and the above person of oral administration 20% paraquat aqua 30mL is also all dead.Though added emetic and warning colouration in the paraquat aqua, aqua is oral easily, causes easily and is poisoned to death.In addition, it is reported that the impulsion phase that oral agricultural chemicals is committed suiside has only 5～20 seconds, if but paraquat made be difficult for oral solid pharmaceutical preparation or glue then can increase the use difficulty, make it spend the impulsion phase as far as possible.Because paraquat has very big toxicity, when preparation paraquat solid pharmaceutical preparation, dust pollution is arranged unavoidably, this life security to the direct labor constitutes very big harm, if but paraquat is made glue, then can solve above problem.But glue is defined as at GB/T19378-2003 " formulations of pesticide title and code ": active ingredient forms the glue-like preparation of true solution behind the dilute with water.
Summary of the invention
The objective of the invention is the problem at existence in the existing paraquat formulation use, is paraquat glue and preparation method thereof but a kind of new paraquat formulation is provided.
But the quality percentage composition of each component is in the paraquat glue of the present invention: paraquat cation 0.1%～30.0%, and emetic 0.1%～1.0%, stink agent 0%～0.5%, thickening synergist 1.0%～90.0%, surplus is a water.
Described emetic is the triazole pyrimidone.
Described stink agent is 2-picoline alkali, 3-picoline alkali, 4-picoline alkali, 2, a kind of or two or more combinations in the pyridine bases such as 3-picoline alkali.
Described thickening synergist is an xanthans, gelatin, gum Arabic, melon glue, sodium alginate, soluble starch, heteroglycan, the basic sodium cellulosate of carboxylic first (second), polyvinyl alcohol, acrylic homopolymer or copolymer and its esters, high molecular polymers such as polyacrylamide, ammonium sulfate, ammonium chloride, ammonium salt and organic amine salts such as ammonium nitrate, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, non-ionic surface active agents such as phenethyl phenol polyethenoxy ether, alkyl (benzene) sulfonate, fatty alcohol polyoxyethylene ether sulfate, lignosulfonates, the alkylnaphthalene sulfonate formaldehyde condensation products, the dibutyl naphthalene sulfonate, anion surfactants such as oleic acid methylamino ethylsulfonic acid sodium, dodecyl benzyl dimethyl ammonium chloride, Dodecyl trimethyl ammonium chloride, a kind of or two or more combinations in the amphoteric surfactantes such as cationic surfactants such as softex kw and betain.
But the preparation method of paraquat glue provided by the present invention is under 10 ℃～100 ℃ temperature, and water, emetic, stink agent, thickening synergist shear-mixed is even, adds paraquat mother liquor shear-mixed then and evenly forms.
But paraquat glue of the present invention has the following advantages:
1, but the paraquat glue is a jelly, and this preparation is difficult for oral, has reduced the danger of oral ingestion.
The pollution of toxicity dust and reduced drying cost and reduced the use of drying equipment when 2, having avoided that paraquat made solid pharmaceutical preparation.
3, can use the liquid state of original aqua use or the wetting and penetrating agent of paste is synergist.
4, can adopt the pack mode of similar toothpaste, no dust pollution during packing.
