1 EC
EC is the original drug is not soluble in water, benzene, xylene, and emulsifiers prepared from transparent liquid, room temperature storage for 2 years are generally not sealed turbidity, stratification and sedimentation, added to the water quickly and evenly dispersed into the opaque Emulsion. EC is characterized by: high efficacy, easy application, with the more stable. Common varieties of EC Triadimefon 10%, 25% Kuwana poisoning. chloro EC, 25% kill EC, 20% EC, etc. Ma Ju. EC production of organic solvents used are flammable materials, storage and transportation process should pay attention to safety. Organic solvents on apples, pears have a stimulating effect in young fruit, skinned fruit can increase the hole and reduce the fruit surface finish, it is recommended not to use EC as possible before bagging, particularly sensitive species and cultivars.
2 Agent
Where can dissolve in water, pesticides in the water without decomposition, can be formulated into liquids. Agent is an aqueous solution of pesticide, chemical state of the ions or molecules dispersed in the water, the concentration of agents depends on the original drug"s water solubility, in general, is its maximum solubility, diluted with water when used again. Agent compared with the EC, no organic solvents, surfactants can increase amount of spray used, less pollution to the environment, manufacturing process is simple, also very good efficacy, the development of a formulation should be. Common varieties of abamectin 2% liquid, 40% of the agent, etc. Isocarbophos.
3 Gum suspension agent also known as SC.
Does not dissolve in water with the original powder and the solid pesticide surfactant, water as the medium, the use of wet ultrafine grinding can be made of viscous flow of the suspension, such as 40% carbendazim plastic hanging agent. With WP compared with powder diameter is small, no dust pollution, the infiltration characteristics of high efficacy, both WP and EC formulations of the advantages of both, can freely mix with water. Prolonged storage, due to the sinking of suspended particles, precipitation phenomena occur, use must be fully shake, so that the lower part of drug re-suspended particles together to ensure the efficacy.
4 Water dispersible granules
Water dispersible granule is solid pesticide, wetting agents, dispersants, thickeners and other additives and fillers mixed granulation process made the rapid collapse of water distributed to SC. Water dispersible granules with good fluidity, easy to use, storage stability, higher active ingredient content of the characteristics of both WP and the suspension of benefits. Water dispersible granules of the active ingredient is generally 50% to 90%, such as 50% water dispersible granule agent imidacloprid.
5 WP
Pesticide is used, inert fillers and a certain amount of additives, by mixing crushed by the proportion, up to a certain degree of fineness of powder formulations. From the formal point of view, with the powder without distinction, but because of added wetting agent, dispersing agent, added to the water, the water can be wet, disperse to form a suspension can be spray applied. Compared with the EC, the production cost is low, the available paper or plastic packaging, storage and transportation convenient, safe, relatively easy to deal with packaging materials; more important is that WP does not use solvents and emulsifiers, safer plants, in Bagging before the use of organic solvents to avoid the stimulation of fruit surface. Common varieties of imidacloprid 10% WP, 70% thiophanate-methyl WP, 80% large hygiene.
6 Concentrated emulsion called EW
By the water-insoluble pesticide, emulsifier, dispersant, stabilizer, thickener, solvent and water is made by the smoothing process is the type of oil in water emulsion, the appearance of opaque oil droplet diameter of 0.2 ~ 2 m . Solvent with EC compared with the savings, environmental pollution, efficacy and the EC rather, is a promising new formulations. The preparation diluted with water before use.
7 Microemulsion Microemulsion
By the active ingredients, emulsifiers, additives such as antifreeze and water, made of transparent or translucent liquid, cream overcome the shortcomings of using a large number of organic solvents, compared with the EC and the use of storage and transportation safety, environmental pollution, drug Liquid irritation in use before bagging to avoid damage to EC on young fruit. Since the formation of very small particle size emulsion, water use can not see the formation of EC on the white water emulsion, which is also called the water-based emulsion, can be melted cream, pharmaceutical dispersed particle diameter 0.01 ~ 0.1 m. Common varieties are 16% efficient microemulsion permethrin, 4.5% high chloride emulsion agent.
