Excellent performance of silicone additives

Hits: 461 img

Silicone additives mainly include the following three aspects of excellent performance: wettability, expansion and permeability.

1. Good wettability
Plant leaves, stems, and insect epidermis often have anti-wetting components or structures, and the leaf surfaces often have negative charges, which have a repelling effect on pesticide liquids. Generally speaking, when the surface tension of the spray liquid is lower than the surface tension of the leaves, the spray liquid will absorb and wet 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 surface tension of organic silicon additives is extremely low, which can easily wet almost all kinds of plant leaves and insect skin, greatly improving the coverage and contact surface of target organisms, reducing the loss of pesticides and improving their utilization efficiency.

2. Super scalability
Silicone additives have super spreading properties. After adding additives, the expanding area is more than 10 times that of pure water. It can make the medicine enter the pest hidden in the back of the leaf or in the gap of the fruit tree, so that the medicine liquid can directly contact or even kill the harmful organism.

3. Excellent permeability
Stomata are one of the main ways for medicine to enter the plant body. Silicone additives can effectively promote the penetration of medicine liquid into the epidermis through the stomata, and the absorption speed is very fast. Studies have reported that silicone additives have a good synergistic effect on abamectin, mainly reflected in the fact that it can make the liquid enter the microscopic pest hiding place, and secondly, it is absorbed by the leaves and enters the epidermis of the plant, prolonging the life of the agent. The residual effect period is longer than that brought by the use of mineral oil additives.
