Documented Uses

• Various mixtures of dichloropropenes are used as fumigants applied to the soil before crops are planted.
• Preplant for nematode, disease, insect control on a variety of crops.
• USED ALONE OR IN COMBINATION WITH CHLOROPICRIN, METHYL ISOTHIOCYANATE, AND METHYL BROMIDE FOR SOIL TREATMENT BEFORE PLANTING OF MANY CROPS. MAJOR SPECIFIC USE SITES INCLUDE COTTON, POTATOES, SUGAR BEETS, TOBACCO, AND VEGETABLE CROPS.
• Breathing in contaminated air; drinking contaminated water; eating contaminated food; dermal and eye exposure (L893).
• MADE BY THE HIGH TEMPERATURE CHLORINATION OF XYLENE TO YIELD ALLYL CHLORIDE AS A PRIMARY PRODUCT. THE 1,3-DICHLOROPROPENE IS SEPARATED FROM THE HEAVY ENDS AFTER REMOVAL OF ALLYL CHLORIDE AS AN OVERHEAD PRODUCT IN DISTILLATION.
• OTHER CHLORINATED HYDROCARBONS MAY BE PRESENT AS IMPURITIES AND STABILIZERS. THESE INCLUDE CHLOROPICRIN, ISOMERS OF DICHLOROPROPANE, DICHLOROPROPENE AND EPICHLOROHYDRIN.
