Abstract

Summary - The effects of methyl bromide, itaconate dimethyl (ID), cadusaphos, and Pas/euria pene/rans on Meicidogyne java­ nica reproduction and gall index and yield of three successive vegetable crops were evaluated. Only methyl bromide treatments achieved a drastic reduction of nematode populations, resulting in low galling indices and significantly increased yield. Soil recolonization by nematodes during the second year was important and caused yield reduction. ID had no nematicidal effect but caused a slight yield increase. Cadusaphos had a delayed effect on nematode build-up and significantly increased yields. During the first crop, Pas/euria pene/rans had no direct effect on nematode populations, gall indices, and yield, but it multiplied actively in the soil. This effectively suppressed nematode populations and reduced gall indices on successive crops, which increased yield. (e) Elsevier - ORSTOM
