Fumigant: A substance that kills pests or diseases in soil or enclosed spaces by releasing toxic gases.
In gardening, fumigants are sometimes used to control soilborne pests like nematodes or diseases that can harm plants. They work by releasing gases that are toxic to these harmful organisms. However, fumigants are generally considered a last resort due to their potential to harm beneficial organisms and the environment.
Fumigants are rarely recommended for home gardeners. They require specialized handling and can pose risks to the user and surrounding environment if not used properly. Safer and more targeted methods are usually available for pest and disease control in a home garden, such as using organic pesticides, practicing crop rotation, or introducing beneficial insects. It’s always best to consult with a local gardening expert or extension service before considering using a fumigant.
