In agricultural operations, the use of various pesticides is essential, but when you buy pesticides, have you encountered such a situation, no matter what pesticides you buy, the dealer will recommend silicone additives to you, then What is the use of this silicone? Let's take a comprehensive look at everything about this silicone additive.
Let's first understand what silicone is:
Silicone additive is a highly efficient and environmentally friendly non-ionic surfactant. Its application has brought fundamental changes to the formulation and application technology of pesticides. Due to its good wettability, expansibility, permeability, good compatibility, and foaming, foam stabilizing and foam suppressing effects, it can significantly improve the utilization rate and application effect in chemical control, and reduce the amount of pesticide dosage by 30%-50% %, effectively reduce pesticide residues, save water, reduce labor intensity, reduce pesticides and increase efficiency, and have been widely used in agricultural production. Today, we will explain the characteristics, applications and usage methods of organic silicon additives, hoping to help farmers understand organic silicon additives and use them reasonably to reduce agricultural production costs and improve control efficiency.

1. Excellent properties of silicone additives
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 leaves 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 expandable silicone additives have super expandability. After adding the additives, the expansion area is more than 10 times that of pure water. This performance can make the sprayed liquid medicine cover the largest area on the leaf surface Covering and adhering can even allow the medicine to enter the pests hidden in the back of leaves or in the gaps of fruit trees, so that the medicine liquid can directly contact or even kill harmful organisms.
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.
