Chloropicrin is a colorless, oily liquid with a pungent odor, primarily used as a pesticide and soil fumigant. It is effective against a variety of pests, including nematodes, fungi, and weeds. Due to its toxic nature, it is handled with caution and requires protective equipment during application. Originally developed as a chemical warfare agent during World War I, Chloropicrin has since found agricultural applications. It is often used in combination with other chemicals to enhance its effectiveness and reduce the risk of pest resistance. Proper safety measures are essential to prevent exposure to this hazardous substance.
