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

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.

Effects of cultivars, subsoiling, and fumigation on soybean yields and Meloidogyne incognita populations.

Application of 1,2-dibromo-3-chloropropane (DBCP) and subsoiling under the row in Tifton sandy loam heavily infested with Meloidogyne incognita increased yields of four soybean cultivars. These cultivars have levels of resistance to M. incognita as follows: 'Hutton', high; 'Essex', intermediate; and 'Davis' and 'Ransom', low. After growing these four cultivars, sub-soiling, and applying DBCP fo...

1,2-Dibromo-3-chloropropane.

Mutation spectrum of 1,2-dibromo-3-chloropropane, an endocrine disruptor, in the lacI transgenic Big Blue Rat2 fibroblast cell line.

1,2-Dibromo-3-chloropropane (DBCP), a soil fumigant against nematodes, has been extensively studied for genotoxicity, carcinogenicity and damage to male reproduction-related organs, as a possible endocrine disruptor. However, the precise mechanisms involved in DBCP-induced mutagenesis and carcinogenesis are as yet unknown. Thus, in this study the mutagenicity and mutation spectrum of DBCP was d...

Recent Investigations Nematodes

Three experiments on the control of nematodes in sugarcane fields are described and res+ults based on yield responses and nematode numbers are quoted. Meloidogyne practically disappeared when the grass, Erugrostis curvula was grown for three seasons, but increased when tomatoes and beans were groyn. Yield responses to nematocides in the absence of Meloidogyne show that this is not the only nema...
