Compositions can be used in the form of dry powders, wettable powders, emulsifiable concentrates, microemulsions, pastes, granulates, solutions, suspensions, etc. The selection of the type of compositions depends on the specific application.
The compositions are prepared in the known method, for example by diluting or dissolving the active substance with a solvent medium and/or a solid diluent, optionally in the presence of surface-active agents.
Solid diluents or carriers which can be used are, for example: silica, kaolin, bentonite, talc, diatomite, dolomite, calcium carbonate, magnesia, chalk, clays, synthetic silicates, attapulgite, sepiolite.

The water is mixed with antifreeze to make a homogeneous aqueous phase. In the high-speed stirring, the aqueous phase is added to the oil phase or oil phase is added to the aqueous phase, forming the water emulsion with good dispersity. The active component of water emulsions is generally 5% −15% in this invention. For the production of concentrated emulsions, the compounds of this invention are dissolved in one or more of the mixed solvent, and then emulsifier was added to enhance dispersion effects in the water.
The preparation of wettable powder: according to formulation requirements, the compound in the invention, surfactants and solid diluents are mixed well, after smashing through ultrafine pulverizer, that is the wettable powder products (for example, 10%-40%). To prepare the spraying wettable powder, the compounds of this invention can form a mixture with solid powder, such as clay, inorganic silicates, carbonates, as well as wetting agents, adhesives and/or dispersant agent.
The preparation of water dispersible granules: the compound in the invention and powdered solid diluents, wetting agents and adhesives are mixed to smash, kneading together with water, added to the granulation machine with 10 to 100 mesh for granulation, then by drying and sieving (at the scope screen). Also, the compound of the invention, dispersants, disintegrants, wetting agents and solid diluent are added to sanding machine, grinding in water to produce suspension and then spray-drying granulation, usually the content of the prepared granular products is 20% -30%.
