Agriculture is the cornerstone of human civilization and undertakes the important mission of food production, economic development and ecological balance. In this context, organic silicon (Organosilicon), as a class of silicon-containing compounds, has received extensive attention and application in agriculture in recent years. It can not only improve the growth environment of crops and promote healthy growth, but also improve the stress resistance and yield of crops, thus providing strong support for the development of agriculture.

Silicone additives are a kind of polyether modified trisiloxane nonionic surfactant. They belong to agricultural additives in application. They are a kind of high-efficiency and environmentally friendly nonionic surfactant with ultra-low surface energy. Due to its good wettability, expansibility, permeability, good compatibility, and foaming, foam stabilizing and foam inhibiting effects, they can be added to fungicides, insecticides (for mites, thrips, red spiders, aphids), herbicides, foliar fertilizers, etc., which can significantly improve the utilization rate and application effect in chemical control, reduce the amount of pesticides by 30%-50%, effectively reduce pesticide residues, save water, reduce labor intensity, reduce medicine and increase efficiency. They have been widely promoted and used in agricultural production, bringing fundamental changes to the formulation and application technology of pesticides.

1 Application of silicone additives in agriculture

1.1 Application in pesticides

Silicone can also be used as an auxiliary for pesticides to enhance the penetration and effectiveness of pesticides. By improving the distribution of pesticides on plant surfaces, organic silicon can improve the control effect of pesticides, reduce the amount of pesticides used, and reduce environmental pollution.

Improve pesticide utilization: The pesticide utilization rate used in most areas is low, usually only about 25%. After adding silicone additives, the effective utilization rate of pesticides can be significantly improved and the waste lost to the soil or air can be reduced.

Accelerate weeding and insecticide: Silicone additives can quickly penetrate weeds and insects, improve control effectiveness, and reduce water and labor costs.

Adaptable to a variety of application scenarios: Silicone additives can be widely used in herbicides, foliar fertilizers and plant growth regulators, significantly improving efficacy and reducing usage costs.

1.2 Application in herbicides

Pesticides are added with organic silicon. After the liquid is sprayed on the surface of weed stems and leaves, it quickly passes through the cuticle and cell plasma membrane, and is finally transmitted to all parts of the plant. After the weeds are injured, the stems and leaves will become bent, deformed, and eventually die. This can significantly speed up the killing of weeds and improve the control effect. At the same time, it can greatly reduce water use and save labor.

1.3 Application in foliar fertilizer

Foliar fertilizer is a quick and efficient way to replenish nutrients, but the impermeability of plant epidermis to inorganic nutrient ions is very detrimental to foliar fertilization, so fertilizing through stomata is a good way. Silicone additives can promote plants to absorb through stomata and improve fertilizer utilization.

1.4 Application in growth regulators

Silicone surfactants can reduce usage and improve usage effectiveness. For example, gibberellin is widely used in citrus, but it is easy to produce antagonistic effects with citrus. Applying agricultural silicone additives can greatly improve the efficacy of gibberellin, and the dosage of gibberellin can also be reduced to 1/10; in Uniconazole Adding silicone additives can improve its wettability and efficacy, reduce the usage of Uniconazole technical material, and reduce the cost of Uniconazole.

 2. Principles for efficient use of silicone additives

Dosage: According to the requirements of different pesticides, the dosage of silicone additives should be reasonably controlled to ensure the best effect and reduce costs. It is generally recommended to use it within the range of 0.025% to 0.1%.

Scope of application: Prioritize the use of silicone additives on crops that are difficult to wet. For crops that are easy to wet, conventional additives can be selected to reduce costs.

Pay attention to mixing: avoid antagonism with certain auxiliaries or pesticides, and ensure that the mixed pesticides and auxiliaries have good compatibility.

Control the concentration: Strictly control the concentration to avoid the occurrence of phytotoxicity, especially when applying pesticides under high temperature conditions.

Ready-to-use: Silicone additives should be mixed with pesticides for immediate use to avoid decomposition.

Prevent environmental pollution: After use, care should be taken to prevent farmland water from flowing into the breeding pond to avoid affecting aquatic life.

Summarize

Silicone additives have very low surface tension, strong spreading ability and fast absorption properties. The rational use of silicone additives can reduce the dosage of pesticides, improve the effective utilization rate of pesticides, reduce production costs, and reduce environmental pollution. However, improper use may also lead to phytotoxicity, so the usage principles and precautions must be strictly followed during application to give full play to its advantages and promote the sustainable development of agriculture.
