Pesticide wetting agents 


Another name:  Wetting agent


Nature:      

Appearance: light yellow or a colourless liquid      

Content: 90%(or according to the need to customize, products containing)      

Ionicity: anion/nonionic


Product introduction:      

Contemporary pesticides commonly used additives is an enhanced liquid, on the plant surface it make a role of Shop morning and attached,it is very important to choose a good wetting agent for the specified crop and pesticide.   

The majority of the plant surface by cornea which containing the wax. These substances constitute a low-energy surface, while the majority of pesticides are often applied form of an aqueous solution. Due to surface tension of water is higher than the critical surface tension of this low-energy surface, so under normal circumstances, the liquid and plant direct contact is not easy to spread in order to improve the wettability of this system. Often in the liquid, add some wetting agent, the wetting effect can plant leaf surface spreading when the minimum concentration of surfactant required to measure, and its essence is to reduce the surface tension of liquid solid, can significantly reduce water the surface tension of surfactant, water-soluble liquid with good wetting.   

Wetting effect in terms of pesticides not only serve to increase the liquid and crop contact area, as well as to maintain the effective concentration of the pesticide, and enhance the absorption of plant, an important role in improve the efficacy. 


The importance of wet effect:

Pesticides, especially the agricultural preparation of the hormone, its role in the play should have the following conditions:

(1) Keep pesticides applied parts (eg leaves) uniform distribution.

(2) Ensure the stability of the concentration in the effective absorption time, however, pesticides applied in a manner often using the spray method. In the case without a wetting agent, there will be too small droplets, spherical or hemispherical distribution in the leaf surface. Crossing the drop radius is smaller, the higher the saturated vapor pressure, evaporation sooner. Small droplet radius of a hundred times, the evaporation rate will increase the times. In view of the spray of results appears this situation: saturation vapor pressure of the large droplets, evaporates slowly to maintain the effective concentration of benefit, however, dispersion does not help full contact with small droplets dispersed leaf, conducive to liquid and foliar contact, but can not guarantee that the effective concentration due to excessive evaporation. Visible, without Billows wet thorns, direct spray of liquid will be difficult to achieve good efficacy.

When you join the appropriate wetting agent. The liquid can rapidly spread into the membrane, thus eliminating the phenomenon of the rapid evaporation of the droplets, both to ensure the stability of the effective concentration of the liquid added to the liquid and foliar full access to sprinkle, so that efficacy can be fully tapped. Visible role of the wetting system is essential.
