What are the characteristics of powder and WP? What is the difference between powder and wettable powder? Can powder and wettable powder be mixed?
Powder and wet powder are two rare pesticide formulations。 The two formulations have different physical and chemical properties。 The application methods are different and misuse must be avoided。 Powder pesticides are made of one or more pesticides, clay, clay and other fillers, which are crushed and mixed by machine processing。 The powder is coarse, and it is not easy to agglomerate, and has good spraying activity and dispersibility。 But the powder is not easy to be wet by water, can not be dispersed and suspended in water, so can not add water spraying, commonly used as powder spraying, high concentration powder can be mixed seeds, soil disposal agent or preparation of poison bait。
Wettable powder is made of one or more pesticides and clay fillers, and a certain amount of detergents such as detergent powder is mixed by machine processing. Its fineness is better than powder, can make hydrophobic powder wet by water, and can be suspended in water on average, its suspension rate is generally more than 60%, can make liquid medicine abundantly adhere to the appearance of animals and harmless organisms, so that the drug carry forward the role of touch or stomach toxicity. Wettable powder is mainly used for water spraying. Because it contains moisture absorbent which can agglomerate or agglomerate the powder, it can not be used for powder spraying. At the same time, it can not be used for poisonous soil spraying or seed mixing. Because of its poor dispersing function and high concentration, it is easy to cause phytotoxicity.
