Pesticides are a very important means of agricultural production and play an important role in ensuring stable and increased output of crops. Pesticide application is a basic and guaranteed production measure for agricultural production. With the development of society and the improvement of people's living standards, food safety, environmental safety, and production safety have received more and more attention and attention from all parties. The Ministry of Agriculture issued the "Action Plan for Zero Growth in Pesticide Use by 2020" in February 2015, to carry out the zero growth in pesticide use across the country.

Silicone additives are highly efficient and environmentally friendly non-ionic surfactants. Its application has brought fundamental changes to pesticide formulations and application techniques. Due to its good wettability, expansibility, permeability, good compatibility, and foaming, foam stabilization and foam suppression, it can significantly improve the utilization rate and application effect in chemical prevention and control, and reduce the amount of pesticides by 30%-50 %, effectively reduce pesticide residues, save water sources, reduce labor intensity, reduce medicines and increase efficiency, and have been widely used in agricultural production.

Today, we will explain the characteristics, applications, and methods of silicone additives, hoping to help farmers learn more about silicone additives, and use them rationally, so as to reduce agricultural production costs and improve control effectiveness.

Plant leaves, stems, and insect skin surfaces often have anti-wetting ingredients or structures, and the leaves are often negatively charged, which repels 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 adsorb and wet on the surface of the plant. On the contrary, the spray liquid will shrink and gather on the surface of the plant, and the droplets sprayed on the surface of the target object will roll off. .

The surface tension of organic silicon additives is extremely low, and they can easily wet almost all kinds of plant leaf surfaces and pest epidermis, greatly improve the coverage and contact surface of target organisms by the liquid medicine, reduce the loss of pesticides, and improve their utilization efficiency.

Organosilicon additives have super spreading performance. After adding the additives, the spreading area is more than 10 times the area of pure water. This performance can make the sprayed chemical liquid cover and adhere to the leaf surface in the largest area, and even reduce The medicament can enter the pests hidden in the back of the leaves or in the crevices of the fruit trees to achieve the purpose of direct contact with the medicinal solution and even killing of harmful organisms.

3. Excellent permeability
Stoma is one of the main ways for the medicine to enter the plant. The organic silicon additives can effectively promote the penetration of the medicine into the epidermis through the stomata, and the absorption rate is very fast. Studies have reported that silicone additives have a good synergistic effect on abamectin, which is mainly reflected in its ability to make the medicinal liquid enter the microscopic pest hiding place, and then it is absorbed by the leaf surface and enters the plant epidermis, prolonging the drug’s effect. Residual effect period, and this residual effect period is longer than the residual effect period brought by mineral oil additives.
