Pesticides of the same composition, different manufacturers have different effects, among which the additives have great factors. Silicone is a kind of auxiliary agent commonly used in pesticides. Silicone can be added to pesticides such as insecticides, fungicides and herbicides. Improve the efficacy. However, the use of silicone should pay attention to some pesticides. The use of silicone may cause phytotoxicity on some crops, which may not be worth the loss.




1. Advantages of silicone


Some work has the following advantages for common auxiliaries, with good ductility and permeability. The ductility can quickly spread the liquid on the surface of the foliage or insects, increasing the contact area between the liquid and the crops, weeds and insects, thereby improving the therapeutic, insecticidal and herbicidal effects. Permeability can also promote the penetration of systemic agents through the pores, and quickly act on plants, thereby improving the ability to withstand rain, reducing the use of pesticides per unit area and water consumption, reducing the waste of pesticides and reducing the environmental impact of pesticides. And residues on agricultural products, saving time, labor and medicine.




2. The drawbacks of silicone


Silicone can improve the efficacy of the drug, but it has a strong destructive effect on the waxy layer of the plant leaves, which will cause the stratum corneum of the leaf epidermal cells to decompose, thereby reducing the plant's resistance to the external environment, which can easily lead to damage of plant cells. . In addition, when the silicone layer is added in a high temperature environment or when the wax layer of the crop itself is relatively thin, it is easy to cause phytotoxicity. Therefore, not every crop is suitable for silicone as an auxiliary agent, and the silicone should be avoided in a high temperature environment.




3. Precautions when using silicone


In addition to avoiding high temperatures, the use of silicone should be strictly in accordance with the instructions, avoid increasing the concentration and avoid causing phytotoxicity. To use silicone, firstly inject half a bucket of water into the container, pour in the silicone, mix well, then pour in the desired agent, then mix well with water.


Although silicone can improve the efficacy of pesticides, it can easily cause phytotoxicity when used improperly, so be careful when using it, pay attention to the crops used and the application environment.
