Meloidogyne Goldi 1877

Root-knot nematodes


- Classification: Animalia, Nematoda, Adenophorea, Tylenchida, MELOIDOGYNIDAE
- English name: Root-knot nematodes
Root-knot nematodes were discovered in the 1850s. The genus Meloidogyne comprises about 100 species. These are extremely polyphagous sedentary endoparasites which attack the melon on which Meloidogyne incognita (Kofoid & White) Chitwood is the most widely reported species.

Root-knot nematodes are widespread worldwide and affect several thousand plants. The Meloidogyne are by far the most common and most damaging of melon; the sometimes considerable damage they cause has been reported in many countries, both in field crops and under cover. In the latter, the losses recorded are often more consequent because of the impossibility of carrying out rotations.

Given the polyphagia of these nematodes on vegetable crops, they are found in France in the soils of many farms, particularly in the past market gardening. Their damage is serious on farms where the management of crop rotations and the sanitary quality of the soil are not good. The disappearance of methyl bromide and the absence of truly effective alternative methods are gradually leading to an increase in the importance of nematode problems on vegetable crops.
