Documented Uses

• Until 1977, DBCP was used as a soil fumigant and nematocide on over 40 different crops in the United States. From 1977 to 1979, EPA suspended registration for all DBCP-containing products except for use on pineapples in Hawaii. In 1985, EPA issued an intent to cancel all registrations for DBCP, including use on pineapples. Subsequently, the use of existing stocks of DBCP was prohibited.
• All uses except on pineapple plantations in Hawaii canceled in 1979; use on pineapples cancelled in 1985; See 29CFR1910.1044;
• Cancellation of all registrations of end use products except for the use on pineapples in Hawaii /as soil fumigant/ (3/31/81)
• Intermediate in organic synthesis; LV (low in volatiles) commercial preparation for the flame retardant tris(2,3-dibromopropyl)phosphate
• Unclassified nematocide used for soil fumigation of cucumbers, summer squash, cabbage, cauliflower, carrots, snap beans, okra, aster, shasta daisy, ornamental turf (lawns), bermuda grass, centipede grass, St Augustine grass, zoysia grass, ardisia, azalea, camellia, forsythia, gardenia, hibiscus, roses, and arborvitae. /Gro-Tone Nematode Granular/ /Former uses/
• Fumigation of pineapple in Hawaii. /Nematocide EM 12.1, Nematocide EM 15.1/
