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 applied pre-plant to treat the soil and is especially effective in high-value row crops and nurseries. Due to its volatility, it penetrates soil effectively, providing broad-spectrum pest control. Often used as a component in mixtures with other fumigants to enhance performance. Its use is regulated due to environmental and health concerns, requiring careful application to minimize emissions and worker exposure.
