Pesticides with high content produced by chemical factories are generally raw materials. Most of the raw materials of pesticides cannot be used directly. They need to be prepared into preparation products by adding solvents and surfactants before they can be used. The solid is called raw powder, and the liquid is called crude oil. Pesticides include various herbicides, fungicides, insecticides, and plant growth regulators.

The characteristics of pesticides powder
1. It is especially suitable for areas with difficult water supply and for preventing and controlling outbreaks of pests and diseases. Generally, it should not be diluted with water, and it is mostly used for dusting and seed dressing. Higher concentrations can be used as poison bait and for soil treatment.
2. It is easy to manufacture and use. The original medicine and inert fillers (talcum powder, clay, kaolin, diatomaceous earth, acid clay, etc.) are mixed and crushed in a certain proportion to make the powder fineness reach a certain standard.
Advantages of Insecticide Powder
(1) Because it is easy to use and does not require water, it can be directly sprayed on crops with a simple duster, and is very popular in arid areas or mountainous areas with difficult water sources.
(2) High efficiency, low adhesion on crops, less residue, and less likely to cause phytotoxicity.
(3) In addition to being directly used for powder spraying, it can also be used for seed dressing, soil treatment, and preparation of poison bait granules to prevent and control diseases, insects, and weeds.
(4) The use of powder is a better pesticide application method in greenhouses and greenhouses.
It is used in the closed environment of greenhouses and greenhouses to prevent and control diseases and insect pests by spraying dust. It can make full use of the movement ability and floating effect of fine powder particles in the air, so that the front and back of plant leaves can be evenly deposited with drugs, improving the control effect, and will not pollute the environment outside the greenhouse.
