powder. Powder pesticides are not easily soluble in water. Generally, water spray cannot be added. Low-concentration powders are used for powder spraying. High-concentration powders are used for preparation of poisonous soil, poison baits, 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 without wind or breeze. Wettable powder. It has strong hygroscopicity and can be dispersed and suspended in water after adding water. Can be used for spray, bait and soil treatment. Soluble powder (water solvent). It can be sprayed or poured directly onto the water.
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, stalking, dressing, and the like. 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, such as trichlorfon oil or marathon oil.
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. Sustained release agent. Slow release of pesticides during use can effectively extend the efficacy period, so the residual effect period is prolonged, and pollution and toxicity are reduced. The usage is generally the same as granules.
Smoke agent. It is a fine powder or ingot 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 agricultural pests and warehouse pests in forests and greenhouses.
