Bromomethane is primarily used as a fumigant to control pests in agriculture, particularly for soil sterilization before planting crops like strawberries, tomatoes, and peppers. It effectively eliminates insects, nematodes, weeds, and fungi, ensuring a pest-free environment for crop growth. In the storage and shipping industry, it is applied to protect grains, dried fruits, and timber from infestations. Additionally, bromomethane is utilized in the production of pharmaceuticals and as a methylating agent in organic synthesis. However, its use is restricted in many countries due to its ozone-depleting properties and environmental concerns.
