Nicotine sulfate is an insecticide derived from nicotine, a compound found in tobacco plants. It has been widely used in agriculture to control pests due to its toxicity to insects. When applied, nicotine sulfate disrupts the nervous system of insects, leading to paralysis and death. However, its use has declined over the years due to safety concerns for humans, animals, and the environment. Prolonged exposure to nicotine sulfate can be harmful to humans and other non-target organisms, making it less favorable compared to safer alternatives. As a result, many countries have imposed regulations on its use, and it is now less commonly used in pest management programs.
