Powder pesticides are easy to store and not volatile, and many farmers will choose such formulations for agricultural production. However, many vegetable farmers have entered a misunderstanding when using powder pesticides. The following are two misunderstandings that vegetable farmers can easily enter:
Myth #1: Pesticide Pesticides All Watered Pesticides Pesticides are made up of a mixture of one or more pesticides and clays, clays, etc. The pulverized powder passes through No. 200 mesh, the powder is coarse, and it is not easy to agglomerate, and has good spray fluidity and dispersibility. However, powders are not easily wetted by water, nor dispersed and suspended in water, so they cannot be sprayed with water. Generally used for dusting, high-concentration powder can be used for seed dressing, soil treatment or preparation of baits.
Myth 2: Wettable powder is used to spray powder. The wettable powder is made up of one or more kinds of pesticides and fillers, clay, etc. It is made by adding a certain amount of washing powder and other wetting agents through mechanical processing. The crushed powder 99.5% through 200 mesh sieve, the fineness is better than the powder, can be wetted by water, and can be uniformly suspended in water, the suspension rate is generally more than 60%, can make the liquid agent fully adhere to the plants and pests On the surface of the body, the agent acts as a contact or stomach poison. The WP is mainly used for water spray. Because it contains a hygroscopic humectant, which can cause the powder to agglomerate or agglomerate, it cannot be used as a powder. At the same time, it cannot be used for poisonous soil application or dressing. Because of its poor dispersion and high concentration, it is easy to produce phytotoxicity.
