SiO2 powder in agricultural industry as an effective pesticide carrier
Silicon dioxide, also known as silica, is widely used in the agricultural industry as an effective pesticide carrier. One of the most common methods of preparing silica for use as a pesticide carrier is precipitation.
Precipitation involves the controlled addition of a suitable source of silicon, such as sodium silicate, to an acidic solution. The resulting reaction forms amorphous silica, which is then collected and dried to produce the final product.
One of the main advantages of using precipitation as a method of silica preparation is that it allows for the production of a highly uniform and consistent product. Additional benefits of using precipitated silica as a pesticide carrier include its high surface area, low bulk density, and excellent water absorbency.
Silica-based pesticide formulations have been shown to be highly effective against a wide range of insect pests and fungal diseases. This is due to the unique properties of silica, which include a highly abrasive surface that damages insect cuticles and desiccates the insect through water removal.
In addition to its pest control properties, precipitated silica has also been shown to improve soil structure and water retention, leading to improved plant growth and crop yields. Overall, the use of precipitated silica has become an indispensable tool in modern agriculture, providing farmers with a highly effective and sustainable means of crop protection.
