Chloropicrin

Chloropicrin (CAS 76-06-2), also known as trichloro(nitro)methane, is a halogenated fumigant used in agriculture to control soil-borne pathogens, nematodes, fungi, and weed seeds ahead of planting.

Where is Chloropicrin used?

• Pre-plant soil fumigation: injected into soil to eliminate fungal pathogens such as Fusarium and Verticillium threatening high-value crops including strawberries, tomatoes, and peppers
• Blended with methyl bromide alternatives or other fumigants to broaden nematode and soil insect control in commodity vegetable and fruit production
• Post-harvest and storage facility treatment: insect and mold control in grain storage structures and processing equipment
• Turf and ornamental growers apply it for soil sterilization in nursery beds and greenhouse substrates prior to transplanting.

Good to know: Tri-clor 99.6 designates the high-purity commercial grade commonly specified in procurement and application contracts, reflecting a minimum 99.6% purity specification standard in commercial agricultural supply chains.

Commercial specifications

• Tri-clor 99.6 grade: minimum 99.6% purity
• Purity and stabilizer content specified per regional regulatory requirements
• Liquid under pressure, typically in cylinders, drums, or bulk containers suited for field injection equipment
