Silicone auxiliaries are used in pesticides. They can be used as spray improvers, leaf absorption auxiliaries, activators and so on. They can be used in herbicides, leaf fertilizers, insecticides or growth regulators.
1. The application of herbicides
After the pesticide is added to organosilicon, the liquid is sprayed on the surface of weed stem and leaf, and quickly passes through the cuticle and cytoplasmic membrane, and finally transmits to all parts of the plant. After the damage of the weeds, the stems and leaves are bent, deformed, and eventually die, which can significantly accelerate the speed of killing grass and improve the control efficiency, at the same time can greatly reduce the water consumption, and save labor.
2, in the application of foliar fertilizer
Foliar fertilizer is a fast and efficient way to supplement nutrients, but the plant epidermis is not permeable to inorganic nutrient ions, which is bad for foliar fertilization, so it is a good way to infiltrate through stomata fertilization. Organosilicon auxiliaries can promote plant absorption through stomatal penetration and improve fertilizer utilization rate.
3, in the application of growth regulators
Organosilicon 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 antagonistic action with citrus. Application of agricultural organosilicon additives can greatly improve the efficacy of gibberellin, and the amount of gibberellin can be reduced to 1/10
2.4 Application in insecticides and acaricides
The stomata of insects are very similar to those of leaves. Organosilicon surfactant can reduce the surface tension of the solution, so that the liquid can penetrate into the trachea of insects, so that it can be used as insecticide additive and synergistic agent.
