This product is also called agricultural organosilicon synergist, pesticide spray assistant, and pesticide expansion penetrant. It is a kind of special modified organosilicon surfactant. The mechanism of action of pesticide enhancers is mainly to inhibit or weaken the detoxification and pest control effects of targets (pests, weeds, pathogens, etc.) on pesticide activity, delay the metabolic rate of the pesticide in the controlled object, and thus increase the biological control effect. The synergist itself is inactive, but when mixed with corresponding pesticides, it can significantly improve its wetting, distribution, dispersion, retention and permeability, reduce the drift of spray liquid with the wind (airflow), prevent or reduce the damage to adjacent sensitive crops, facilitate the spread and adhesion of liquid medicine on the leaf surface, reduce the decomposition of effective ingredients in pesticide preparations by ultraviolet light, and achieve the purpose of prolonging the validity period of efficacy, improving its biological activity, reducing dosage, reducing cost, and protecting the ecological environment. Good synergists can not only increase the effectiveness of pesticide control several times or tens of times, but also delay the development of resistance and extend the lifespan of hard-earned pesticide varieties.

The basic composition of pesticide synergists is organosilicon polyoxyethylene ether compounds, which have low surface tension, good spreading, permeability, and emulsifying dispersibility. They are a new and efficient pesticide additive. It is easily soluble in methanol, isopropanol, acetone, xylene and dichloromethane, and can be dispersed in water. It can be used as spray improver, leaf absorption assistant, activator, etc.
