Nicotine sulfate serves multiple purposes primarily in the agricultural sector. It acts as an effective insecticide, targeting pests such as aphids, caterpillars, and leafhoppers, disrupting their nervous systems and leading to their eventual demise. Additionally, nicotine sulfate finds utility as a fumigant, safeguarding stored grains and commodities from infestations by insects like grain weevils and beetles. Its role extends beyond practical application, as it also serves as a subject of scientific research, facilitating studies on nicotine's impact on biological systems and aiding in the development of novel insecticides.
