Used primarily as a soil fumigant in agriculture to control nematodes, fungi, and weeds before planting crops such as vegetables, tobacco, and strawberries. It is effective in high-value farming systems where soil-borne pests can significantly impact yield. Applied through drip irrigation or soil injection, it helps prepare the ground for planting by creating a pest-free environment. Due to its volatility, it requires careful handling and application under regulated conditions to minimize environmental and health risks. Often used in combination with other fumigants to enhance efficacy.
