Agricultural silicone additives, i.e. silicone compounds. It is mainly composed of ethoxy-modified trisiloxane, which is a polyether-modified special organosilicon surfactant.
The role of agricultural silicone additives:
1) Organosilicon has wetting properties, which can make the liquid medicine spread rapidly on the leaf surface and insect body, thereby increasing the contact area between the liquid medicine and crops and insects, and improving the effect of insect control and weeding;
2) Silicone can promote the penetration of liquid chemicals through pores, improve the ability of liquid chemicals to resist rainwater scouring, and then improve the efficacy;
3) Silicones can increase the coverage of the liquid chemicals on the leaf surface and reduce the loss of the liquid chemicals.
Mechanism of action of agricultural silicones:
Agricultural silicone additives mainly reduce the surface tension of the liquid medicine on the leaves, so that the liquid chemicals can quickly spread and penetrate in the leaves.
The better the quality of the silicone, the lower the surface tension between the interfaces, and the better the elongation effect of the solution.
High-quality silicones are highly resistant to rain washout. When spraying pesticides to prevent pests and diseases in the rainy season, choosing high-quality silicone additives can greatly improve the efficacy.
Silicones for herbicides:
The extremely fast spreading ability can make the liquid spread quickly, resist high temperature transpiration, and use on some grasses in the middle of summer, silicone can have an unexpected good effect.
This silicone product is suitable for the mixed use of pesticide varieties of re-contact type, but it is necessary to pay attention to the systemic mechanism of action of the agent, and the amount of use needs to be strictly controlled, otherwise it will cause pesticide damage and reduce production.
Silicones for biocides:
On the one hand, silicone can increase the contact area between the liquid and the leaves, so that the liquid can cover the leaves of the plant more evenly, and the spores of the pathogens can be contacted to improve the effect of disease prevention and treatment. In addition, crop diseases mainly invade from stomata and wounds, and organic silicon can promote the entry of fungicides from the stomata of crops and play a role in disease control.
