Is silicon dioxide a pesticide

Silicon dioxide and silica gel were first registered as pesticides in 1960 and 1956. Currently, 18 registered pesticide products contain silicon dioxide, and 55 contain silica gel, usually in combination with other active ingredients. Silica or silicon dioxide is the second largest quantity of cement ingredients, about 17 to 25%. Silica can be obtained from sand, argillaceous rock, etc. A sufficient quantity of silica helps form di-calcium and tri-calcium silicates, which impart strength to the cement. Silicon dioxide (SiO2), the most abundant compound in the Earth's crust, is Silicon's most common compound. It commonly takes the form of ordinary sand but also exists as quartz, rock crystal, amethyst, agate, flint, jasper, and opal. Silicon dioxide is extensively used in the manufacture of glass and bricks. Silica (SiO2) occurs commonly in nature as sandstone, silica sand, or quartzite. It is the starting material for the production of silicate glasses and ceramics. Silica is one of the most abundant oxide materials in the Earth's crust. Silicon dioxide can exist in crystalline (quartz) and amorphous (fused silica) forms. The crystalline has three polymorphic forms: cristobalite, tridymite, and quartz. Silicon dioxide is generally safe as a food additive, though some agencies call for stricter guidelines about the quality and characteristics of the silicon dioxide found in foods. People can experience adverse effects of silicon dioxide if they inhale the fine particles. China is the world's largest silicon producer, with a production volume estimated at six million metric tons in 2022. Russia was the second largest producer of this metalloid in the world, which produced 640,000 metric tons in the same year.
