Abstract
The invention belongs to the field of herbicides, and relates to a synergist and synergist-containing diquat aqueous solution. The synergist is aqueous solution prepared by mixing an anionic surfactant and a nonionic surfactant in a ratio of 1:5-10:1, wherein the anionic surfactant and the nonionic surfactant serving as active ingredients account for 30 to 60 percent of the total weight of the synergist. Each liter of synergist-containing diquat aqueous solution comprises the following components: 100 to 300g of diquat cations serving as an active ingredient, 10 to 200g of synergist, 0.25 to 0.75g of emetic, 0.1 to 2g of deodorant, 0.1 to 1g of guard pigment and the balance of water serving as a solvent. The diquat aqueous solution has high weeding activity, and the synergist can improve the viscosity of the aqueous solution, so that liquor can be prevented from splashing and the absorption rate of the diquat aqueous solution by people who take the diquat aqueous solution by mistake can be reduced in the using process, and the safety of diquat products is improved.
Description
Technical field
This patent belongs to the weed killer herbicide field, relates to a kind of synergist and contains the diquat aqua of this synergist.
Background technology
Diquat, international diquat by name, chemical name be 1,1 '-ethylene-2,2 '-duplex pyridine dibromo salt, be a kind of bipyridyl herbicides.
Diquat just has destruction to the lipid of plant double membrane structure synthetic and chloroplast, photosynthesis is stopped, the rapid dehydration of plant, withered death, because of it has quick-acting, wide spectrum, advantage such as passivation rapidly in soil, so it is widely used in land for growing field crops, orchard, uncultivated area weeding, also be applied to preventing and kill off of aquatic weed abroad, simultaneously diquat still be a kind of desiccant of contact efficiently, can be used as breaking of wheat, paddy rice, cotton, soybean, potatoes and other crops harvesting front and back withered, accelerate the ripening and the seed drying agent.
Diquat is as a kind of bipyridyliums, quick-acting tagging property weed killer herbicide, activity of weeding and paraquat are suitable, can prevent and treat multiple 1 year or perennial weed, especially preventing and kill off those broad leaved weeds, has good effect, therefore to paraquat generation resistance, development is like a raging fire on the agricultural chemicals market abroad, become after glyphosate, paraquat, the big steriland herbicide in third place in the world, and just stranger for the domestic market.
But bipyridyl herbicides, people and animals had very strong toxic action, main oral administration causes poisoning, also can causing in skin is taken in body poisons causes death, so in this series products, add emetic, warning colouration and peculiar smell agent etc., prevent to wrongly take with stomach and it is absorbed the raising security of products.In addition, product itself has certain viscosity, can reduce flow velocity, can further improve the bipyridyl herbicides security of products.
Summary of the invention
The purpose of this invention is to provide a kind of synergist of developing at diquat specially.
Another object of the present invention provides a kind of diquat aqua that contains this synergist.
The objective of the invention is to be achieved through the following technical solutions:
A kind of synergist, this synergist is to develop at diquat specially, this synergist aqueous solution that to be anion surfactant and non-ionic surface active agent mix with 1: 5～10: 1 mass ratio, wherein anion surfactant and non-ionic surface active agent active ingredient total content are 30～60wt%.
The anion surfactant that is fit to synergist of the present invention is selected from one or more any combination in alkyl sulfate, alkylnaphthalene sulfonate, lignosulfonates (as sodium metnylene bis-naphthalene sulfonate NNO), sodium sulfate of polyethenoxy ether of fatty alcohol (as ethoxylated alkyl sulfate AES), alkylphenol polyoxyethylene phosphate ester salt (as the NP-10 phosphate), alkyl phenol formaldehyde resin polyoxyethylene ether sulphate (as SOPA), the aerosol-OT salt.
The non-ionic surface active agent that is fit to this patent synergist is selected from any combination of one or more in embedding thing (as No. 34, peaceful newborn No. 33 or peaceful breast), styrene phenol formaldehyde resin APEO (as peaceful newborn No. 700), alkyl phenol formaldehyde resin polyoxyethylene ether (as Nongru-700 number), castor oil polyoxyethylene ether (as By110 or By125), the fatty alcohol-polyoxyethylene ether (as peregal) altogether of phenethyl phenol polyethenoxy ether (as agricultural emulsifier NO), polyoxyethylene polyoxypropylene.。
The mass ratio of described anion surfactant and non-ionic surface active agent is 1: 1～5: 2.
The preparation method of described synergist is: select above-mentioned anion surfactant and non-ionic surface active agent according to the certain quality ratio, dissolve respectively, mix with suitable quantity of water, supply moisture, after stirring, promptly formed synergist of the present invention.Described water can be deionized water, also can be running water, preferably deionized water.
A kind of diquat aqua that contains described synergist is a solvent with water, and diquat is an active ingredient, and each component content is:
Preferred preparation constituent is combined as:
Described emetic is PP796, and its chemical name is 2-amino-6-methyl-4-n-pro-pyl-(1,2,4) triazole-pyrimidones (5), and this emetic is 400 ± 50: 1 with the ratio that adds quality of active ingredient diquat.
Described water can be deionized water, also can be running water, preferably deionized water.
Described peculiar smell agent and warning pigment are this area kind commonly used.Can be pyridine as the peculiar smell agent, 2 picolines, 3 picolines etc. wherein one or more; The warning pigment can be light blue.
The viscosity scope of diquat aqua of the present invention is between 150～300mPas, and preferred viscosity is between 200～300mPas.
The pH value of described diquat aqua is pH4～8.
The invention has the beneficial effects as follows:
(1) activity of weeding height, the present invention utilizes surfactant and the composite aqua of making of diquat, and herbicidal effect significantly improves, under regular service conditions, its effect and paraquat are suitable, and control Mazus japonicus etc. paraquat are had aspect the broad leaved weed of resistance, and effect is even more ideal.
(2) synergist among the present invention is to develop at diquat specially, it can provide good wetting infiltration capacity, enhancing medicament adhering to and the dishcloth performance on grass cutting blade for diquat, significantly improve the activity of weeding of diquat aqua, and because the unique collocation of anion and non-ionic surface active agent makes this synergist to diquat good thickening power be arranged.
(3) safety is good, the adding of this synergist is brought up between 200～300mPas the viscosity scope of diquat aqua, pourability and bucket that this viscosity helps medicament mix the spraying use, the more important thing is and improved security of products, can avoid aqua to splash in production and use, personnel burn.In addition, after the people wrongly takes this medicament, owing to medicament viscosity reason, not only can reduce the amount of swallowing, and the slow flow velocity of soup in stomach can fall, stop soup to enter the small intestine that can absorb soup, thereby win more time for the absorption of the emetic in the medicament from stomach, make diquat be absorbed enter blood before, just discharge the liquid contain diquat by vomiting.
