Methods of using pesticides
1、 Powder. Powders are not easily soluble in water and cannot be spray with water. Powders with low concentration are used for powder spraying, while powders with high concentration are used for preparing toxic soil, bait, seed dressing and soil treatment. The powder is easy to use and has high work efficiency, and should be used in the morning and evening when there is no wind or weak wind.
2、 Wettable powder. Strong hygroscopicity, can be dispersed or suspended in water after adding water. It can be used for spray, poison bait and soil treatment.
3、 Soluble powder (water solvent). It can be directly sprayed or poured with water.
4、 Emulsion (also known as emulsifiable concentrate). The emulsion is an emulsion after adding water, which can be used for spray, sprinkling, seed dressing, seed soaking, toxic soil, stem coating, etc.
5、 Ultra low volume formulation (oil). It is a medicament directly used for spray, and it is a special supporting pesticide for ultra-low volume spray. Water cannot be added when using it.
6、 Granules and microparticles. It is a pesticide formulation made of granules using pesticide raw materials and fillers, which is not prone to drug harm. Mainly used for heart and leaf irrigation, sprinkling, spot application, seed mixing, ditch application, etc.
7、 Sustained release agents. The slow release of pesticides during use can prolong the efficacy period, thus prolonging the residual efficacy period and reducing pollution and toxicity. The usage is generally the same as that of granules.
8、 Smoke agent. Smoke agent is a fine powder or ingot made from pesticide raw materials, fuels, oxidants, combustion aids, etc. This pesticide formulation vaporizes when heated and condenses into solid particles in the air, forming a smoke like form. It is mainly used to control forest, facility agriculture pests, and warehouse pests.
