Pesticides used for spraying are not volatile. Fumigants are volatile that spread evenly all over the storage area. Nowadays, with the increased use of non-volatile, thermally labile pesticides (imidazoles, benzimidazoles, carbamates, neonico- tinoids, benzoyl ureas, etc.), techniques other than GC/MS are needed to analyze the complete range of commonly used pesticides Fumigant, any volatile, poisonous substance used to kill insects and other animals or plants that damage stored foods or seeds, human dwellings, clothing, and nursery stock.soil fumigants are sprayed or spread over an area to be cultivatedand are worked into the soil to control disease-causing fungi, nematodes, and weeds.
