Zinc phosphide is a chemical compound made up of zinc and phosphorus, commonly used as a rodenticide. It appears as a gray or black powder and is effective in controlling pests like rats and mice. When ingested, it releases phosphine gas, which is toxic to these animals. This compound is often applied in agricultural settings to protect crops from rodent damage. However, it is important to handle zinc phosphide with care, as it can also be harmful to humans and pets if ingested. Proper safety measures should be taken when using this substance.
