Used primarily as a soil fumigant in agriculture to control nematodes, fungi, and weeds before planting crops such as vegetables, fruits, and tobacco. It is effective in pre-plant applications for high-value crops where soil-borne pests can significantly impact yield. Commonly applied in sandy or well-drained soils, it helps improve crop health and productivity. Due to its volatility, it is often incorporated into soil immediately after application to reduce emissions and enhance efficacy. Its use is regulated to minimize environmental and human health risks.
