Nicotine sulfate is a chemical compound derived from nicotine, commonly used in agricultural applications as an insecticide. It is formed by combining nicotine with sulfuric acid to create a soluble salt. Nicotine sulfate works by disrupting the nervous system of insects, leading to paralysis and eventual death. It is often utilized in crop protection to control pests such as aphids, caterpillars, and leafhoppers. However, its use is restricted in many countries due to its high toxicity to humans, animals, and the environment. Proper safety precautions should always be followed when handling and applying nicotine sulfate.
