Abstract
The present invention belongs to a pesticide for preventing and controlling several pests on cotton, peanut, soybean, fruit tree and vegetable. The cyhalothrin suspension concentrate is characterized by being prepared by mixing and homogenizing the following raw materials in percentage by weight: 0.1-30% of cyhalothrin, 1-20% of cosolvent, 1-8% of emulsifier, 0.1-20% of suspending agent, 0.1-5% of adhesive, 0.2-8% of effective component stabilizer and the balance of water. The product has the characteristics of wide insecticidal spectrum, high activity, quick drug effect, rain wash resistance after spraying and the like. Because only a small amount of toxic and flammable organic solvent is contained, the environment-friendly glass has no fire hazard, no unpleasant and toxic odor and little irritation to eyes, reduces the pollution to the environment and greatly improves the safety of production, storage, transportation and users.

The invention belongs to a kind of agricultural chemicals, particularly a kind of is that active ingredient is the colloidal suspending agent agricultural chemicals and the production method thereof of dispersion medium with water with the Cyhalothrin.
Background technology
China's pesticide industry is started late, and is lagging behind developed country especially aspect formulations of pesticide development and the exploitation, and former medicine is 1: 6 with preparation than only, and this ratio of developed country has reached 1: 30, and both differ greatly.Present stage China the formulations of pesticide also mainly based on missible oil, pulvis, wetting powder and granule, the agricultural chemicals of these several formulations accounts for the 70-80% of total amount of formulation, wherein cream preparation accounts for about 50% of total amount, only this item will consume at least 30 ten thousand tons organic solvent every year, so not only wasted a large amount of industrial chemicals, and brought huge environmental pressure, and because the combustibility of organic solvent in the missible oil all is very limited at aspects such as production, storage, transportation, container selections.Current, the research and development and the improvement of the formulations of pesticide all attached great importance in countries in the world.Succeeding in developing of novel form not only can prolong the life cycle of old kind, saves medication, reduces cost, and can make that high-toxic pesticide is low to be poisoned, and reduces and pollutes, and economizes on resources, and can reach efficient, safe, economic target.In recent years, in states such as American and Britain, in the pesticidal preparations to the restriction increasingly stringent of organic solvent, some developed country's dimethylbenzene has disabled trend, especially on vegetables, fruit tree, use missible oil to run into strong resistance, thereby impel the continual renovation and the development of pesticidal preparations, wherein Water-borne modification is one of dominant direction of formulations of pesticide development.Therefore, replace the colloidal suspending agent of organic solvent in the missible oil just to arise at the historic moment, make it become pesticides new formulation and be developed and applied, and will develop into leading formulation with part water.
Cyhalothrin (English common name: Lambda-cyhalothrin; Chemical name: 3-(2-chlorine=3,3,3-fluoro-1-acrylic)-2,2-dimethyl ethylene-acetic acid cyano group (3-Phenoxyphenyl) methyl esters; Other title: time, cyhalothrin, cyhalothrin, Kung Fu) be one of kind that insecticidal activity is the highest in the present pyrethroid pesticide, its insecticidal activity is higher 4 times than cypermethrin, higher 8 times than sumicidin, be genuine efficient chrysanthemum ester insecticide.Its desinsection wide spectrum can be widely used for preventing and treating the insects such as mite class on cotton bollworm, diamond-back moth, cabbage caterpillar, leaf miner, aphid, beet armyworm and the vegetables fruit tree.Have extremely strong tagging and stomach poison function, its insecticidal activity is higher, and the speed of knocking down is fast, is a kind of quick-acting insecticide.Preparation after processing increases at the crop surface plate-out ability, sprays the back resistance of rainwater washing against; Different with other chrysanthemum ester insecticide is that it has good inhibitory effect to the mite class, to sumicidin, decis being produced slight drug-fast pest population, use Cyhalothrin and mixture thereof, still have the better prevention effect, cross resistance is not obvious.
The Cyhalothrin formulation that present domestic registration is produced is many based on missible oil, has the registration of a small amount of producer that the Cyhalothrin aqueous emulsion is arranged, but does not find the registration and the report of relevant cyhalothrin suspension concentration both at home and abroad as yet.
Summary of the invention
The object of the present invention is to provide a kind of is the colloidal suspending agent and the production method thereof of active ingredient with the Cyhalothrin, for the insects such as mite class on control cotton bollworm, diamond-back moth, cabbage caterpillar, leaf miner, aphid, beet armyworm, the vegetables fruit tree provide a kind of efficient, quick-acting, safe advanced formulation, particular content is as follows:
