Resumo
Planting-time applications of ethylene dibromide (Soilbrom(?) 90EC) and a mixture of ethylene dibromide (EDB) containing 27% (w/w) chloropicrin (Terr-O-Cide(?) 72-27) were compared with DBCP (1,2-dibromo-3-chloropropane) for effectiveness against Meloidogyne arenaria (Neal) Chitwood, M. hapla Chitwood, and race three of Heterodera glycines Ichinohe on soybeans (Glycine max (L.) Merr.). Field tests conducted at three different locations in Alabama demonstrated that the two formulations of EDB were as effective as DBCP in controlling the parasite and in incrementing yields of Bragg or Ransom soybeans. No phytotoxicity was detected from planting applications of EDB containing fumigants at rates of 37.41 L/ha or below.
