Abstract
Four methods of placement of DBCP (l,2-dibromo-3-chloropropane) and a single method of application of ethoprop (0-ethyl S,S-dipropyl phosphorodithioate) wexe compared in each of two areas for control of nematodes on soybeans. One area was a Marlboro sand infested with Hoplolaimus columbus. The other area was a Fuquay loamy sand infested with Meloidogne incognita. Soybean yields were increased and numbers of H. columbus in the row 0-20 cm deep were decreased similarly by all methods of DBCP application in Marlboro soil. All DBCP treatments increased the average soybean yields and decreased numbers of M. incognita larvae in the row 0-20 cm deep in the Fuquay soil. Average root-knot indices were reduced by all DBCP treatments except with placement 40 cm deep beneath the row. Similarly, placement of all or part of the DBCP 20 cm deep and 13 cm to either side of the row resulted in greater average yields than placement of the DBCP 40 cm deep. Apparently, control of M. incognita is more critical 0-20 cm deep than 20-40 cm deep for increasing soybean yields. DBCP did not control H. columbus as effectively as it did M. incognita. Control of H. columbus and M. incognita was not obtained at 0-20-cm and 20-40-cm depths 30 cm and 45 cm from the row regardless of the method used to apply DBCP. H. columbus and M. incognita were controlled more effectively and soybean yields were higher with DBCP at 13.6 kg a.i./ha than with ethoprop at 4.5 kg a.i./ha.
