Application of organosilicon additive in agriculture


In agricultural operation, it is necessary to use all kinds of pesticides. But when you buy pesticides, do you encounter this situation? No matter what pesticides you buy, the dealers will recommend organosilicon additives to you. What is the use of organosilicon? Let's have a comprehensive understanding of all about this organosilicon additive.


Let's first understand what organosilicon is:


Organosilicon, in a broad sense, refers to a compound containing Si-C bond, and at least one of which is a compound with organic group directly connected to silicon atom, which is called organosilicon compound. Farmers know these contents. The application of organosilicon in agriculture began to be commercial only in the 1980s. The extensive application of organosilicon has made great contribution to the elimination of toxicity and environmental pollution in agriculture. Why do you say that?






Farmers know that in the process of crop management, we must use pesticides, but the use of pesticides also has disadvantages. The first is cost, the second is environmental pollution. The cost of pesticide production is high and the price is also high. If a large number of pesticides are used, the cost of farming will increase and the income of farmers will be reduced. However, for the environment, a large number of pesticide use leads to environmental pollution and pesticide residues, which seriously affects the ecological environment. In the process of using pesticides, if the concentration is too low, it will not have the effect of killing insects. If the concentration is too high, it will easily lead to drug damage, and the pesticide residues exceed the standard to pollute the environment.






Adding pesticide synergist is the most widely used method. Pesticide synergist is an important adjuvant in pesticide, which has no activity. However, when it is mixed with the corresponding pesticide, it can obviously improve the utilization rate of pesticide. Organosilicon is the most widely used synergist in agricultural production. What are the characteristics of organosilicon mixed with pesticides?


1. The excellent wettability of organosilicon makes the liquid medicine spread rapidly on the leaf surface, enhances the adhesion of liquid medicine, improves the utilization rate of pesticide, reduces the loss of liquid medicine, avoids the penetration of pesticide into the ground and causes water pollution.


2. organosilicon auxiliaries can significantly enhance the adhesion and expansion of the liquid on the surface of plants or pests, increase the utilization rate of pesticides, speed up the absorption of pesticides by pests, and improve the insecticidal effect to a certain extent, thereby reducing the number of spraying and reducing the use of pesticides.

3. Organosilicon promotes the penetration of the internal absorption agent through the pores to improve the rain erosion resistance. After rain, there is no need to spray again.


4. It can reduce the amount of pesticide use and water consumption per unit area, reduce pesticide pollution and pesticide residue. It can be used with insecticides, fungicides and plant growth regulators.






So the problem is, since the effect of organosilicon mixed with pesticides is so good, is it possible for our farmers to add organosilicon auxiliaries to any pesticide? Obviously not!


In order to make money, some dealers of agricultural materials are purposely promoting organosilicon, because there will be no adverse reactions if the organosilicon additive is added or not, which is also the reason why dealers of agricultural materials dare to strongly recommend it. So how should farmers choose?


A. not all pesticides need additives


Some pesticides have already added some surfactants in the production process, and if these pesticides are used, adding organosilicon and other additives again may cause harm. In recent years, azoxystrobin, a new fungicide with high efficiency and broad spectrum, has strong conduction permeability. If farmers add organosilicon adjuvant again in the application, it will enhance the permeability of pesticides and easily cause crop damage. The same is true for some herbicides, such as dimethylpentylene, which is widely used in vegetables. The herbicide itself has a strong permeability. If it is mixed with organosilicon additives, because of the very low expansion of organosilicon, it is very easy for the herbicide to spread to the plant tissues through the pores of the crop leaves, resulting in drug damage.


B. less is better than more in actual use


The use amount of organosilicon must be used in strict accordance with the instructions. Do not increase the concentration at will, which is very easy to cause drug damage. At the same time, it is better to avoid high temperature application before 10 a.m. and after 4 p.m.
