- This species is restricted to carrot.
- These small nematodes gain entry to the roots, either by piercing the epidermis with their stylet or by through wounds. They extract the contents of cells and inject toxins, thus destroying cells.
At the time of reproduction, females swell and make the bark of radicles burst, their head remaining attached to the plant (*) .
- This nematode shows a high ability to multiply and, in the presence of suitable hosts, numbers can increase tenfold at each crop.
- In the field, the presence of this nematode is indicated by patches of irregular plant growth which enlarge from one year to the next if crops remain susceptible due to rotation.
- Affected carrots are small. Radicles are abnormally developed and numerous, which gives to the roots a characteristic bearded appearance (*) . The stunted and reddish foliage may dry out in case of heavy attacks (*) .
