Guidelines For The Use Of Agricultural Silicone

Silicone auxiliaries 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, and foaming, foam stabilizing and foam suppressing effects, it can significantly improve the utilization rate and application effect in chemical control, and can reduce the dosage of pesticides by 30%-50%, effectively To reduce pesticide residues, it has been widely used in agricultural production.

Silicone auxiliaries are used in pesticides, and can be used as spray modifiers, foliar absorption aids, activators, etc., and can be used in herbicides, foliar fertilizers, insecticides or growth regulators.

1. Application in herbicides

Organic silicon is added to the pesticide. After the liquid is sprayed on the surface of weed stems and leaves, it quickly passes through the cuticle and cytoplasmic membrane, and finally transmits to all parts of the plant. , to achieve the purpose of rapid weed removal.

2. Application in foliar fertilizer

Foliar fertilizer is a fast and efficient way to replenish nutrients, but the impermeability of plant epidermis to inorganic nutrient ions is very unfavorable for foliar fertilization, so infiltration and fertilization through stomata is a good way.

The organic silicon additive can promote the plant to absorb through stomatal infiltration and improve the utilization rate of fertilizer.

3. Application in growth regulators

Silicone surfactant can reduce the amount of use and improve the use effect. For example, gibberellin is widely used in citrus, but it is easy to produce antagonism with citrus. The application of agricultural silicone auxiliaries can greatly improve the efficacy of gibberellin, and the dosage of gibberellin can also be reduced to 1/10.

4. Application in insecticides and acaricides

The stomata of insects are very similar to the stomata of leaves. Silicone surfactant can reduce the surface tension of the solution, allowing the liquid to penetrate into the trachea of insects, making them dead. It is of great significance as an insecticide auxiliary and synergist.

However, silicone auxiliaries are also chemical auxiliaries, and there are some precautions when using them.

1. Strictly control the use concentration of silicone auxiliaries and strictly control the dosage. Determine the appropriate concentration of organic silicone auxiliaries mixed with different types of pesticides, some powerful insecticides and herbicides should pay attention to reduce the amount of use to prevent adverse effects.

2. Do not apply pesticides under high temperature conditions. It is best not to add organic silicone auxiliaries when spraying pesticides when the temperature exceeds 30°C. Strong and easy to cause phytotoxicity to crops. When spraying on fruit trees, do not spray directly on the fruit to prevent rust spots and rust spots. It is best to apply it after fruit bagging.

3. Ready to use. Silicone auxiliaries are easily decomposed under acidic and alkaline conditions, and most pesticide preparations are obviously acidic. Therefore, when using organic silicone auxiliaries, they should be used as soon as possible after they are formulated with pesticides.

Silicone auxiliaries can reduce the amount of pesticides used, improve the effective utilization of pesticides, reduce production costs, and reduce environmental pollution caused by pesticides.

However, improper application of silicone auxiliaries may also lead to phytotoxicity, such as some crops with a thin waxy layer on the leaves and easy to be wet, or increasing the concentration without authorization in order to increase the effect.

Therefore, when using silicone auxiliaries, you must keep in mind the precautions and principles of use, and give full play to the effects of silicone auxiliaries according to their different characteristics.
