Economic Impact of Nematodes

  • Annual crop losses to world agriculture-est $100b and $8b in US
  • Some of most damaging pests of tropical, sub-tropical and temperate agriculture.
  • Root - knot nematodes (RKN) are the most destructive world wide

What are nematodes?

  • Small microscopic worm-shaped animals (0.5-10mm)
  • Other shapes (round, pear shaped)
  • 25% infect animals and plants
  • High fecundity & short life cycle
  • Occupy every habitat (freshwater, marine, brackish, terrestrial)
  • Numerical dominant - 80,000sp

  9. 1994-10-19 Information about nematodes affecting agroforestry trees. Nematodes are tiny “wire worms” that abound in the soil. The root-knot nematode,Meloidogyne incognita, is one of the most infamous, both for its devastating effect on crops and the ease with which its presence can be identified. The...
  10. Access Agriculture Training Video Nematodes are dreadful worms that live in the soil and in the roots of many different crops and weeds. Nematodes are easier to prevent than to control. The secret is to: grow healthy seedlings; destroy all sources of nematodes in and near your vegetable field;...
