Methyl isothiocyanate is primarily used as a soil fumigant to control a wide range of soil-borne pests, including nematodes, fungi, weeds, and insects. It is effective in sterilizing soil before planting crops, ensuring a pest-free environment for optimal plant growth. The compound is often applied in agricultural settings, particularly for high-value crops like strawberries, tomatoes, and potatoes. It works by releasing toxic gases that penetrate the soil, eliminating harmful organisms. Additionally, it is used in the production of certain pesticides and herbicides. Due to its high toxicity, proper handling and application protocols are essential to ensure safety and environmental protection.
