The use of different pesticides

SC (SC)

It is the original drug is dispersed or suspended solids contain a variety of additives in aqueous medium or oil medium, high concentration of viscous flowable formulations. Commonly used in expensive and efficient pesticides, use of conventional spray, but also for low-volume spraying and soaking, etc., which both WP and EC two formulations advantages, but at present the ideal suspension narrow range, in recommended the use of tobacco, 36% thiophanate-methyl colloidal suspension agent.

Agent (AS)

The water-soluble in water directly into the original drug formulations. The formulation process is simple, easy to use, efficacy, and ease of packaging, transport and storage, garden hand sprayers can reduce the pollution of organic solvents, but agent intolerance storage, easy hydrolysis lapse poor wetting, adhesion is weak, Vinca is very long, and There are limitations, not all pesticides can be processed into liquid.

Seed (SD)

Seed are those containing a binder and a certain pesticide or fertilizer plant growth regulating agents encapsulated in plant seeds on the outside and the formation of a solid dosage form of the drug layer. It is often treated seeds can be stored for a short time, usually tobacco seeds are treated with a seed coating. Most of the commonly used Seed preparations contain a variety of active ingredients, with pest control, to provide nutrition and promote plant growth and development role.

Fumigants (VP)

In the appropriate temperature, the use of toxic gases, liquids or vapors generated by the evaporation of a solid in a closed environment, kill pests or pathogens, called fumigation. Called fumigants used for fumigation agents. Fumigants are easily vaporized liquid or solid, some compressed gases. While some soil treatment or portable power sprayer spray process with fumigation, but can not be called fumigants, such as acephate fumigation has some activity, but the main mode of action is to stomach poisoning and toxicity, and therefore can not become a fumigant , there is a real sense of aluminum phosphide fumigant, methyl bromide, etc.
