Surfactant of pesticides

Organic silicon compound surfactant of pesticides include a range of structural types. They are not like many commonly used surfactants with linear structure, instead they are t-shaped structure. They are all made up of methylated siloxanes skeleton with a or more polyether tail. Surfactants as an adjuvant in pesticide not only improve the effect of pesticide use, but also reduce the amount of pesticides, reducing the impact of pesticides on the environment, and bring huge benefits for agricultural production.
Processing of pesticide formulation can not be without surfactant, they need to add different types of surfactants. The addtion of surfactant greatly reduces surface tension of solution. Currently the applied in use pesticide surfactants mainly are fatty alcohol polyoxyethylene, alkyl-phenol polyoxyethylene ether, sulfonate, sulfonic acid ester, amide, silicone, etc. Pesticide surfactant itself had no insecticidal and fungicidal effect, but its emulsifying properties and their exhibition will affect the efficacy of pesticides. At present, the main difference of the ingredient and the same domestic agents is that the agent of surfactant in the application.

Silicone additives for its good agro-silicone additives have good exhibitions, permeability. It has increased efficiency, labor-saving, water conservation, and provincial drug features in the spraying of pesticides. Agricultural spray silicone additives can help increase yields and reduce the adverse effects of pesticides on the environment, which can allow spraying agricultural chemicals have a better efficacy, spreads more easily and absorbs quickly and is not easy to be washed down.

Specifically, these additives can make solutions containing pesticides, growth regulators and other chemical are easier to penetrate plant surfaces. This ability to spread meant that only a small amount of spray can get the spray effect. At the time of spraying pesticides, it can save up to 50% of water. This can reduce waste, reduce the losses to the amount of pesticide in the soil and groundwater, thereby reducing pesticide residues in the environment.

On the biological effect of some surfactants such as cationic surfactants, which itself has a bactericidal effect. People take advantage of the nature develop herbicides, plant growth inhibitors. Saponin is a good non-ionic surfactant is a botanical insecticide. 12 alkyl benzene sulfonic acid sodium salt (potassium) has a strong effect of lysozyme, it is available to a wide spectrum of chemical sterilization bacteriolytic effect of fungicides when it combined with organic nitrogen compounds with biological activity. But not all surfactants are used in pesticides, since some surfactant of pesticides have a phytotoxic effect on crops. Therefore pesticide use of surfactant in addition to depending on the original drug choices, but also take into account its impact on the crop. Click here!
