Susceptibility of the larvae of three species root-knot nematode (Meloidogyne spp.) to ethylene dibromide

Abstract

Susceptibilities to ethylene dibromide were compared among the second-stage larvae of the root-knot nematodes, Meloidogyne incognita, M. hapla and M. javanica by the modified Moje method. Garden pea was used as a host, and the nematodes were reproduced under the same conditions. As a result of tests, LC-50s of each species varied from 53 ppm to 60 ppm. The larvae of the three Meloidogyne species tested were considered to be approximately equal in their susceptibility to the nematicide.
