The pesticides of the same composition have different effects from different manufacturers. Among them, the auxiliary agent has a large factor. Silicone is a commonly used auxiliary agent on pesticides. Adding silicone to pesticides such as pesticides, fungicides, and herbicides can Improve efficacy. However, pay attention to some pesticides when using silicones. The use of silicones may cause phytotoxicity on some crops, which may result in losses.




1. The advantages of silicone


Some work as common additives have the following advantages, have good ductility and permeability. The ductility can make the medicinal solution spread quickly on the leaf surface or insect surface, increase the contact area of the medicinal solution with crops, weeds, and insects, thereby improving the effects of disease treatment, insecticide and herbicide. Permeability can also promote the penetration of systemic agents through stomata, which can quickly act on plants, thereby improving the ability to withstand rainwater, reducing the amount of pesticides and water used per unit area, reducing pesticide waste, and reducing the impact of pesticides on the environment And residues on agricultural products, saving time, labor and medicine.




2. The disadvantages of silicone


Organic silicon can improve the efficacy, but it has a strong destructive effect on the waxy layer of plant leaves, which will cause the cuticle of the leaf epidermal cells to break down, thereby reducing the resistance of the plant to the external environment and easily causing damage to plant cells. . In addition, in high temperature environment or when the waxy layer of the crop itself is thin, adding silicone can easily cause phytotoxicity. Therefore, not every crop is suitable for silicone as an auxiliary agent. In addition, use of silicone should avoid high temperature environment.




3. Matters needing attention when using silicone


In addition to avoiding high temperature, the use of silicone should be used strictly in accordance with the instructions. Do not increase the concentration arbitrarily to avoid causing harm. When using silicone, generally put half a bucket of water into the container, then pour in the silicone, mix well, then pour the required medicine, and then inject water to mix well.


Although organic silicon can improve the efficacy of pesticides, improper use can easily cause phytotoxicity, so use it with caution and pay attention to the crops used and the application environment.
