ROOT-KNOT NEMATODES: MELOIDOGYNE

Root-knot nematodes occur throughout the world. It attack more than 2000 species of plants, including almost all cultivated plants, and reduced the world crop production about 5 %. Losses in individual fields, however, may be much higher.
Root-knot nematodes damage plants by devitalizing root tips and causing formation of swellings of the roots. These effects not only deprive plants nutrients but also disfigure and reduced the market value of the crops.
