In agriculture, the treatment of seeds with white carbon black mixed with trace elements, growth regulators and mineral fertilizers can protect the seeds from mechanical damage and moisture, increase seed germination rate and reduce fertilizer use, shorten maturity and increase Yield of crops.
In the herbicides such as acesulfame/bensulfuron-methyl, chlorfenapyr/bensulfuron-methyl, etc., the dispersibility and adsorption of the fumed silica can ensure the strong adsorption of the herbicide and the long-lasting effect. In a mixture of two common herbicides, dinitroaniline and urea, a small amount of fumed silica is added to prevent agglomeration of the mixture.
In insecticidal powders such as polythiane and phoxim, the use of fumed silica as a carrier and dispersant will facilitate the storage, transportation and use of pesticides, avoid the use of organic solvents, reduce environmental pollution and reduce The production cost increases and prolongs the efficacy.
The fumed silica is also used as an absorbent for soil contaminants to absorb contaminants in the soil.
