"Silicone" is one of the most widely used synergistic pesticide additives (surfactants) in agricultural production. It can be used with pesticides, fungicides, herbicides, regulators and foliar fertilizers, which can significantly improve the spraying effect of pesticides or foliar fertilizers. The role characteristics of silicone are mainly the following 5 points:

First, it can enhance the ductility of liquid medicine
The so-called ductility is "expansibility", without silicone pesticides or leaf fertilizer sprayed on plant leaves, leaves will appear a lot of water droplets; And added "organic silicon" pesticides or foliar fertilizer sprayed on the leaves, agents obviously can not see small water droplets, liquid medicine can achieve the maximum coverage and adhesion effect, can significantly improve the efficacy.
Because of the improvement of the ductility of the liquid medicine, the spraying liquid medicine will also spread to the back of the leaf or the gap of the fruit tree, the absorption effect of the medicine, the effect of killing insects and sterilization will be significantly improved, and the prevention and control will be more thorough.
Prevention of drug harm, need growers scientific use of drugs: understand the nature of drugs, according to the guidance of agricultural technical guidance personnel; When mixing pesticides, it is best not to have more than three varieties; Most pesticides are best diluted twice before they are used. It is best to match and use now.
Two, can improve the ability of liquid rain resistance
The addition of organic silicon foliar fertilizer or pesticide can improve the adhesion of the liquid to the solid surface, so that the pesticide is more resistant to rain washing or wind blowing, and can significantly improve the retention of the liquid.
Normally, if it rains within 3 hours of spraying, the pesticide needs to be re-sprayed, and if there is sustained rain after spraying, the duration of the pesticide will be shortened. Silicone increases the adhesion of pesticides on leaves or stems, and the pesticide lasts longer.
Three, can enhance the permeability of liquid medicine
Silicone can enhance the permeability of liquid medicine, such as in the spraying of foliar fertilizer, plant absorption rate and utilization rate of foliar fertilizer will improve, help to improve fertilizer efficiency; When sprayed with herbicide, the herbicide will be quickly absorbed by weeds, which can improve the killing effect of weeds.
For example, some pests will cover the surface of the plant layer by layer (such as aphids), spraying chemical agents is difficult to kill the internal pests, but adding silicone insecticides will improve the permeability, which can significantly improve the effect of pesticides on pest control. Some bacteria are very good at hiding, chemical agents are difficult to completely remove, in the fungicide added silicone, fungicide can effectively kill the colony.
Four, can reduce the use of pesticides
Because silicone can enhance the efficacy, we can reduce the number and concentration of foliar fertilizer or pesticide spray. Compared with the liquid without silicone, the same volume of spray can reduce the foliar fertilizer or pesticide use by 30%.
At the same time, because silicone can increase the retention period of the solution, we can reduce the number of spraying or increase the time between spraying. For example, under normal circumstances, the pesticide is sprayed once every 7 to 10 days. With the addition of silicone, we can increase the spraying interval time under the condition of reducing the dosage. We can spray once every 10 to 15 days.
Five, can improve the efficacy of liquid medicine
This is understandable, since silicone can improve the malleability and permeability of the solution, so the solution can be sprayed more quickly. In the spraying of trace elements fertilizer to add silicone, trace elements will be quickly absorbed by the plant, can prevent deficiency disease; When the plant is diseased, adding organosilicon in pesticides can make pesticides quickly absorbed by bacteria, and the effect of disease prevention and control is faster.
How to add silicone to foliar fertilizer or pesticide?
Silicone has different specifications, we take 10% agricultural silicone water agent as an example, a barrel of 30 kilograms of liquid medicine, can add 10 grams of 10% agricultural silicone water agent. Silicone alone has no effect, it needs to be mixed with pesticides or foliars, and it should be used within 4 hours as far as possible after the efficacy of the spray.
