Silicone additives mainly include the following three aspects of good performance: wettability, expansion and permeability.
1. Good wettability
Plant leaves, stems and insect cuticle often have moisture-resistant components or structures, and the leaves are often negatively charged, which repel pesticide liquids. Generally speaking, when the surface tension of the spray liquid is lower than the surface tension of the leaf, the spray liquid will absorb the wetting on the plant surface; otherwise, the spray liquid will shrink and gather on the plant surface, and the droplets sprayed on the surface of the target object will roll down.
The silicone additives surface tension is very low, can easily wet almost all kinds of plant leaves, insect pests epidermis, greatly improve the coverage and contact surface of the drug solution to target organisms, reduce the loss of pesticides, improve its use efficiency.
2, super expansion
Organic silicon fertilizer has a super show performance, and after joining agent, exhibition area is more than 10 times of pure water area, and the performance can make the spraying the solution of the large coverage and adhesion on the leaf, you can even make the potion into leaves on the back or pests of fruit tree of hiding place, achieve the goal of liquid direct contact or even kill harmful organisms.
3. Excellent permeability
Stomata is one of the main ways for pharmaceutical products to enter the plant body. Silicone additives can effectively promote the drug liquid to penetrate into the epidermis through stomata, and the absorption rate is very fast. According to the research report, the silicone additive has a good synergistic effect on avermectin, which is mainly reflected in that it can make the drug liquid enter the microscopic hiding place of pests, and then be absorbed by the leaves and enter the plant epidermis, and prolong the residual period of the drug, and the residual period is longer than that brought by the mineral oil additive.
