There are many types of pesticides, and their application methods are also different. If improperly applied, it is easy to cause phytotoxicity or prevention and treatment. The following describes the characteristics and methods of use of several different types of pesticides:
First, powder. Powder is not easy to dissolve in water, generally can not be sprayed with water, low-concentration powder for powder spraying, high-concentration powder for preparation of poisonous soil, poison bait, seed dressing and soil treatment. The powder is convenient to use and has high work efficiency, and should be used when there is no wind or weak wind in the morning and evening.
Second, wettable powder. It has strong hygroscopicity and can be dispersed or suspended in water after adding water. Can be used for spray, bait and soil treatment.
Third, soluble powder (water solvent). It can be sprayed or poured directly onto the water.
Fourth, the emulsion (also known as emulsifiable concentrate). The emulsion is an emulsion after adding water, and can be used for spraying, pouring, seed dressing, soaking seeds, poisonous soil, and coating stems.
5. Ultra low volume preparation (oil agent). It is a direct-use spray agent. It is a special supporting pesticide for ultra-low-volume spray. It cannot be added with water.
Sixth, granules and microgranules. It is a pesticide formulation made of granules using pesticides and fillers. This dosage form is not easy to cause phytotoxicity. Mainly used for filling heart, spreading, point application, seed dressing, ditch application, etc.
7. Slow release agent. The slow release of pesticides during use can effectively extend the efficacy period. Therefore, the residual effect period is prolonged and the pollution and toxicity are reduced. The usage is generally the same as granules.
Eight, smoke agent. The smoke agent is a fine powder or a spindle made of a pesticide, a fuel, an oxidant, a combustion improver, or the like. This type of pesticide is vaporized by heat and condenses into solid particles in the air to form a smoke. It is mainly used to control forests, facilities, agricultural pests and warehouse pests.
