In the 1960s, trisiloxane polyether structure of organic silicone surfactant began to be applied in Agricultural Chemistry industry, and it was not popularized in the field of pesticides until the 1980s.
    Pesticides are essential chemicals in the production of crops, fruits and vegetables. They are used to kill pests, pathogens and weeds. Since most pesticides (including herbicides) are oil soluble and insoluble in water, they must be emulsified into oil in water emulsion before use. When used, add water to a very low concentration; spray or otherwise apply to crops, fruits, vegetables and weeds on the leaves, stems and stems, and kill or inhibit the growth of all kinds of pests, germs and weeds. The surface tension of general surfactant aqueous solution is above 30 mN/m, while that of organic silicone surfactant aqueous solution is mostly about 20 mN/m. The surface tension of water solution is directly related to the wettability and wetting speed of water solution on solid surface, especially hydrophobic surface. The smaller the surface tension, the faster the water solution wets solid surface, and the larger the wetting area or spreading area. There is a thin layer of hydrophobic wax film on the surface of the leaves, stems and stems of plants. The emulsified pesticide emulsion with general surfactant is applied to the leaves, stems and stems of plants, and the wetting speed is slow and the spreading area is small. Because of the capillary effect, many small porous pesticides do not penetrate, and the pests and diseases that have not been wetted by pesticides can still survive. It is also of no help to weeds that need to be removed, because herbicides cannot penetrate into the capillaries of weeds. Adding a small amount of organic silicone surfactant in herbicide formulation can reduce the amount of herbicide by more than one third. Because the surface tension of silicone surfactant is very low, it can make the emulsion quickly wetting and penetrate the plant's surface.

    Surface tension comparison of organic silicone surfactants:

        The surface tension of water is 72.4 mN/m.

        Minimum Surface Tension of Conventional Hydrocarbon Surfactant Solutions ~30mN/m

        Surface Tension of 0.1% OF-77 Solution ~20.5mN/m
