Movement and Persistence of 1,2-dibromo-3-chloropropane in a Soil with a Plow-pan.

Soil fumigation: principles and application technology.

The principal soil fumigants and their order of discovery are carbon disulfide, chloropicrin, methyl bromide, 1,3-dichloropropene, ethylene dibromide, 1,2-dibromo-3-chloropropane, and methyl isothiocyanate. Biological activity of soil fumigants ranges from limited to broad spectrum. Fumigants diffuse through the continuous soil air space as gases. Physical and chemical characteristics determine...

Efficacy of 1,2-Dibromo-3-chloropropane for Control of Meloidogyne javanica as Influenced by Concentration, Exposure Time and Rate of Degradation.

Laboratory experiments were conducted by applying 1,2-dibromo-3-chloropropane (DBCP) to sealed vials of soil infested with Meloidogyne javanica. A minimum initial concentration of 0.25 mug of DBCP/g of oven-dry soil killed all nematodes within 35 days. A concentration of 1.0 mug/g killed all nematodes within 28 days. The rate of degradation of this chemical was determined by treatment of steame...

Potential hazards of fumigant residues.

A spectrum of fumigants (primarily ethylene dibromide, 1,2-dibromo-3-chloropropane, ethylene oxide, symdibromotetetrachloroethane, 1,3-dichloropropene, dichlorovos, carbon tetrachloride, methyl bromide) as well as their degradation products in foodstuffs and soil have been examined mainly in regard to the potential mutagenicity of their residues.

Coastal Bermudagrass Rotations for Control of Root-knot Nematodes:.

The use of 1,2-dibromo-3-chloropropane (DBCP) and e thy lene d ib romide (EDB) as soil fumigants to control nematodes has been banned. Other nematicides are more expensive and often less effective than DBCP and EDB and may experience a similar fate. A renewed interest in biological control o f nematodes will surely follow. Among root-knot nematode-resistant crops that may be used in rotation wi...
