[0006] At present, the patent application No. 200910225145.0 discloses the synergistic compounding of polyaspartic acid and glyphosate, but its dosage form is only dispersible powder, soluble powder and water of glyphosate, which can improve the suspension of the preparation when used alone. The effect of the rate is not good, and the use of auxiliary dose is large
The patent application number is 201210257508.0 discloses the use of Iraqi / Mongolian clay to prepare inorganic bactericidal suspensions, and the Iraqi / Mongolian clay is applied to inorganic copper sulfate suspending agents alone, and the suspension rate of copper sulfate reaches 90%, but if the Iraqi / Mongolian clay is used In other solid preparations such as WP and WDG where / Mongolian clay is used alone for other pesticide active ingredients, the suspension rate of the active ingredient is lower than that in copper sulfate, and the dosage used is also large, so the single application of Iraqi / Mongolian clay is limited. The scope of applicable pesticide active ingredients and dosage forms is relatively narrow
In addition, there are no other reports on the application of polyaspartic acid and I / Mon clay in pesticide preparations
And about the combination of polyaspartic acid and Yi / Mongolian clay, there is never any report to be used in the field of pesticide preparation production

Abstract
The invention discloses a synergistic carrier composition for solid pesticide preparations. The composition is composed of 1-30mass% of polyaspartic acid and 70-99mass% of illite / smectite clay. The synergistic carrier composition has the advantages of reduction of the consumption of a pesticide assistant, cost saving, suspension rate increase, drug effect enhancement, obvious quality improvement and obvious cost reduction when 3.5-55mass% of the composition is used in solid pesticide preparations comprising a wettable pulvis, a water dispersible granule and the like as a carrier.
Description
technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a synergistic carrier composition for pesticide solid preparations. Background technique [0002] Polyaspartic acid is a polymer of amino acids, which belongs to biopolymer materials. It occurs naturally in the shells of molluscs and snails, where it regulates the calcium balance of these organisms. Its molecular weight is from one thousand to hundreds of thousands. In addition to the properties of water-soluble carboxylic acid, it also has the characteristics of easy degradation, so it is widely used in water treatment agents, detergents, cosmetics, bacteriostats, dispersants, chelating agents It is an environmentally friendly chemical with a wide range of uses, non-toxic, non-polluting, and easy to degrade. Polyaspartic acid salt has a good dispersing effect on inorganic and organic substances; high molecular weight polyaspartic acid has strong water absorption...
