Abstract
The present application relates to the use of Daucus carota plants which do not belong to the Daucus carota subsp. sativus subspecies of cultured carrots to disinfect a culture medium infested with Heterodera carotae nematodes, using the nematicidal power of the plants. The present application also relates to Daucus carota plants which are resistant to the Heterodera carotae nematode, and to methods for culturing such plants which make it possible to reduce the population of Heterodera carotae nematodes present in a culture medium.

A method for reducing the population of Heterodera carotae nematodes in cultivation medium infested with such nematodes, comprising cultivating Daucus carota plants which do not belong to the sub-species of cultivated Daucus carota subsp. sativus carrots, wherein said plants have a nematicidal effect on said nematodes.
A population of plants or seeds of Daucus carota plants, obtained or derived from seeds deposited under the accession number NCIMB 42351, wherein said plants have a nematicidal effect on a population of Heterodera carotae nematodes.
A method for disinfecting a soil contaminated by the carrot cyst nematode Heterodera carotae, comprising cultivating in said contaminated soil Daucus carota plants resistant to said cyst nematode and which do not belong to the sub-species of cultivated Daucus carota subsp. sativus carrots, so that to restrict the multiplication of the nematode thereby disinfecting the soil.
