Abstract
The invention discloses thickening composition for sodium salt of 2-methyl-4-chlorophenoxy acetic acid. The composition comprises tetrasodium ethylenediamine tetraacetic acid accounting for 2%-6% of the total weight of the composition, at least one or more surfactants which are represented by (A)-(C) and account for 15%-70% of the total weight of the composition and the balance of water. The invention further discloses a preparation method and an application of the thickening composition. The composition is specially applied to a sodium salt of 2-methyl-4-chlorophenoxy acetic acid aqueous solution and used for replacing conventional aids without thickening effects, the adhesion of the solution to leaf surfaces can be improved, medicine losses caused by mutual collision and friction of plant leaves due to rain washing and wind blowing can be reduced, and the usage effect can be improved.
Description
Technical field
The present invention relates to field of pesticide chemistry, be specifically related to a kind of thickener composition for methoxone sodium and Synthesis and applications thereof.
Background technology
Chemical herbicide advantages, remarkable benefit, agricultural production is widely used.But, because Different Crop or same origin different cultivars (being) drug resistance to weed killer herbicide there are differences, if unreasonable use can cause the problem such as poisoning, environmental pollution.Methoxone sodium is phenoxy carboxylic acid parahormone type selective herbicide, has stronger Uptake and translocation, can be used for the gramineous crops such as paddy and wheat, corn, Chinese sorghum, sugarcane and prevents and kill off annual and perennial broadleaf weed.
How reducing pesticide dosage, improve the effect after dispenser, be the problem that people pay close attention to always.Find that in pesticidal preparations, add auxiliary agent is reach the effective ways being easy to use, improve drug effect, reduce Pesticide use by research, it also has the effect reducing use cost, prolongation medicament shelf life and market life, be beneficial to protection insect natural enemy, reduce environmental pollution in addition.And agricultural chemicals thickener is exactly the one in these auxiliary agents, it can play increases agricultural chemicals to the adhesion of target and deposition, reduce due to rain drop erosion, blowing causes plant leaf mutually to collide and the medicament loss caused that rubs, reduce agricultural chemicals to the pollution of environment, reach the effect in Control pollution source, this today day by day strengthened for environmental consciousness is significant.
Methoxone sodium is insoluble in water, be soluble in the organic solvent such as ethanol, ether, its usable floor area at home and abroad constantly expands, and the exploitation of its auxiliary agent used generally only pays attention to sprawling of plant leaf surface, and does not cause enough attention to the adhesiving effect of plant leaf surface.And use thickening type auxiliary agent can improve the adhesion of liquid on target blade face, reducing the consumption of weed killer herbicide, improving herbicidal effect aspect and have very important significance.Common thickener composition cannot increase the viscosity of preparation when preparing methoxone sodium aqua, and easily occurs lamination, thus affects its herbicidal effect.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the invention provides a kind of stable and there is the thickener composition for methoxone sodium of certain viscosity, and disclose its methods for making and using same.Said composition is specifically designed to methoxone sodium aqua, the conventional auxiliary agent without thickening effect is substituted with this composition, the adhesion minimizing rain drop erosion of liquid on blade face can be improved, blowing causes plant leaf mutually to collide and the medicament loss caused that rubs, and improves result of use.
For solving above-mentioned the deficiencies in the prior art, technical scheme of the present invention is as follows: a kind of thickener composition for methoxone sodium, it is characterized in that, said composition comprises and accounts for composition total weight 2%-6% tetrasodium ethylenediamine tetraacetate, and account at least one or the surfactant shown in multiple (A)-(C) of composition total weight 15%-70%, surplus is water:
