VEXTASIL series organo silicone spray adjuvant


VextaSil Pro Spray Adjuvant is a superspreading surfactant. VextaSil Pro spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.

Typically, as an adjuvant and surfactant in tank mixtures for the introduction of ground pesticides ground, air, ultra-small ground spraying.



Helps improve rainfastness

Promotes rapid uptake of agrochemicals

Promotes spray volume reduction

Low pour point for low temperature applications

Low foaming



Additionally, VextaSil Pro Proposes to increase the efficiency of pesticides and microfertilizers for foliar nutrition by reducing the surface tension of liquids, which contributes to the uniform and full spread of the working solution on the plant surface. VextaSil Pro improves the flow of the working solution to the apical meristem and absorption sites, such as: shoots, lower parts of the leaves, stems, sinuses, bark of trees. VextaSil Pro significantly accelerates the absorption of the working solution through the stomata of the plant, improves the stability of the working solution to the washings with precipitation. VextaSil Pro distributes the working solution on the planed and covered with a thick layer of wax plaque on the surfaces of plants.

Usually, VextaSil Pro is used at concentrations of 0.02 - 0.1% in working mixtures at pH 6 - 8. As practice shows, there is enough 40-50 ml / hectare VextaSil Pro about 100-200L of water.

In Agrochemical Formulations

VextaSil Pro spray adjuvant may be used as a component in agrochemical formulations. Although organo silicone surfactants are subject to hydrolysis under acidic or basic conditions, optimum performance is achieved by buffering the formulation to pH 6.5 -7.5.

As A Tank Mix Adjuvant

VextaSil Pro spray adjuvant, when used as a tank-side adjuvant may be used to improve spray coverage, improve uptake or to allow for a reduction in spray volume. VextaSil Pro spray adjuvant is most effective as a tank-side adjuvant when spray mixtures are 1) within a pH range of 6-8, and 2) used within 24 hours of preparation.

High spray volumes, coupled with high surfactant rates, are not required to achieve sufficient coverage with VextaSil Pro spray adjuvant. In fact, VextaSil Pro pray adjuvant may provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%.



After sealing packaging products stored in a cool, dry, well ventilated place, VextaSil Pro has a shelf life of 36 months from date of manufacture.
