Abstract
Plant parasitic nematodes are severe pests of many vegetable crops in France and proper management of them is necessary for satisfactory crop performance.
Therefore, in 2009 and 2010, trials with dimethyl disulfide (DMDS) were undertaken to control nematodes in greenhouse on melon and lettuce, and in open-fields on early potatoes and carrots.
In the open-field trials, DMDS was used in shank application (pure product) using different kinds of machineries, at the rates of 240, 300 and
400 kg/ha on carrots and compared with 1,3-dichloropropene at 160, 170, 190 or
240 L/ha (commercial product), and at 300 and 400 kg/ha on potato and compared with 1,3-dichloropropene at 160 or 190 L/ha.
In the greenhouse, DMDS was used in drip application (EC formulation) using a pressurisable container and pipes disposed under a gastight film, at 200, 400 and 600 kg/ha in comparison with
1,3-dichloropropene at 170 L/ha.
The results show that DMDS greatly controlled the root-knot nematode, Meloidogyne sp., in greenhouse on lettuce and melon.
Under field conditions, DMDS controlled this nematode, Pratylenchus sp. and Heterodera carotae on carrot and Globodera pallida on potato.
Therefore, DMDS appears as a promising alternative to existing fumigants to control several nematode species that damage vegetable crops under field and greenhouse conditions.
