What are the commonly used pesticide formulations?

(1) powder. Grinding the original pesticide and filler into a very fine powder mixture. Generally, clay and talcum powder are used as fillers, which have no insecticidal effect and do not react with chemicals, but only dilute the pesticide concentration. Because powder is generally insoluble in water, it can not be sprayed on water, and can be used to spray powder, toxic soil and so on.

(2) Wettable powder. In the process of processing pesticides, in addition to fillers, there are also a certain amount of wetting agents, such as tea cakes, Gleditsia sinensis, washing powder and so on. After adding water, it can be wetted by water, can be uniformly suspended in water, and can be used as spray, heart filler, poison bait, etc. Such as 65% zineb wettable powder.

(3) emulsifiable concentrate. A transparent oily liquid made of pesticide, emulsifier and solvent can be used for spraying and soaking seeds. Such as 40% omethoate EC.

(4) particles. A granular medicine is prepared by mixing the original medicine with a carrier (clay, gypsum, slag, etc.). ) Mix evenly in proportion. Such as 5% phoxim granules. Mainly used for diffusion in soil.
