Hyperosmotic promoter in Agrochemicals:
The new Azoneproducts are newly developed special promoters for agrochemical production byGaojin company. Added the products agrochemicals can enhance their efficiency.After spraying, the liquids can spread fast and well distribute on the surfaceof plants and pests, destroy their protective wax layers, promote the activeagents penetrate through into
pest body. Therefore, not only the efficiencyis enhanced significantly but also deduce the dosage of the active agents byabout 50% at same control efficiency. As the new Azone products can be usedeasily they are welcomed by formers, and very helpful for some new typepesticides extendin the market.
To guarantee the demands of pesticideproducers domestic or abroadfor different formulations some kinds of Azoneproducts are developed as follows:
Oil soluble Azone: mainly be used in agrochemicals with EC formulation, not dissolved inwater.
Water soluble Azone: can be used in aqueousformulation.
Powdering Azone: can be used in WPformulation.
New Azonc products are the most efficient permeatable promoterin agrochemicals.
Using Azone the hyperosmotic 12% Mieshajing (EC) wasworked out and had been lined in the list of national key S&T extensionprograms. Thenews was reported by People's Daily on the Nov. 7, 1995. Anothernewly developed agrochemical product, the High-efficient herbicide 42%Hyperosmotic Acetochlor-atrazine (aqueous flowable formulation), was reported byPeople's Daily on May 4 1997. It was trial-produced and get through theprofessional appraisal. Now the new Azone products have beenused successfullyin some other new herbicides with different formulationssuch as Bentazone (EC),Acetochlor (EC), Butachlor (EC), and Glyphosate(Aqueous solution).
The newAzone products are colorless or light yellowish liquids with the goodcharacteristics in stinkless, odorless, nonpoisonous, and non-inflammable. Theproducts can solve in organic solvents such as toluene,acetone, alcohol etc, andalso have excellent property in emulsificationandmixture.
Usage:applying the new Azone products directlyinto? the agrochemicals during their production The adding amount is around0.5-2% of the agrochemicals' weight, normally 1%.
New Azone are appliedwidely in the organophosphorus, pyrethrum,carbamates pesticides and the mixtureof some pesticides, fungicides andherbicides.

3. Functional mechanism
Azone has the hypertonicity to effectthe ordinary cell construction of cuticle in living things' surface, make thelipoids under skin to be fluid, promote active agent get through the skin intobody fast directly to the target and enhances the effectivity of theagent.
1>. Functional mechanism on pests：Most pests are insects .Intheir surface there is protective wax layer and cuticle. When Azone applied intocontact-poison type pesticide it can help the pesticide infiltrate with pestsurface, make up a well distributing effective film, destroy pest cuticlestructure, then reduce the pest's defense, promote pesticides get into pest bodyeasily and arrive the target fast.For stomach poison pesticide Azone can destroythe inner membrane of stomach, help the effective agents be absorbed and arrivethe target fast to kill the pests.
2>. Functional mechanism on plantpathogens：Using Azone can promote fungicides penetrate the cell wall ofplant
pathogens fast to enhance their affectivity.
3>. Functionalmechanism on herbicides：Most serious harmful herbs have a heavy wax layer ontheir surface,which act as a defensive cover. Azone can help herbicides evenspread on the surface, destroy the wax layer structure, make the effectiveagents get into herbs and arrive target fast then kill the herbs.
Generallyspeaking, adding Azone can save active agents by 30-70% at the same efficiencyfor a agrochemical product, increase the active speed by 2-5 times and lengthenthe active period more than 3-7d, which lead the Agrochemicals into highefficiency, less poisonous, fast and persist action.
Azone applied in agrochemicals:
The good osmosis ofmake Azone be used more and more widely in theproductions of medicine,pesticides, animal medicine, dyeing-printing,leather making, beauty cosmetics,health-prot
