The recent banning of the most active chemical nematicides raised root-knot nematodes (RKN) as the major problem of vegetable growing in the south-east of France, with over 40% of horticultural farms affected. Resistant (R) cultivars successfully limit nematode attacks of the crop itself and reduce nematode abundance in soil in the short term....

Current restrictions on the use of chemical nematicides have led to an increase in root-knot nematode (RKN) damages in horticultural crops. The effects of two sorghums as summer cover crops, Sorghum sudanense sudan-grass cv. 'Piper' or sudangrass hybrid [S. bicolor x S. sudanense] '270911', respectively with low and high dhurrin contents, were...

Plant-parasitic nematodes (PPN) are detected everywhere as mixed-species communities. Most non-chemical control strategies of PPN only target some species, thus raising questions about the consequences that this specificity may have on the residual community. In this respect, the long-term ecological sustainability of such strategies is...

Design and assessment of innovative Mediterranean vegetable cropping systems to manage root-knot nematodes Description of the subject. A system approach based on co-design and experimental field evaluation of cropping systems (CSs), combining technical and varietal innovations, has been implemented for sustainable management of root-knot...

Root-knot nematodes (RKN, Meloidogyne spp.) is a major disease in sheltered vegetable crops, present on about 40% of the southern France farms (survey 2007 -2010). As most chemical nematicide products are now banned, it is necessary to find alternative solutions using agronomical techniques. New prototypes of cropping systems have been built...

The current restrictions on the use of chemical nematicides have contributed to increased root-knot nematodes (Meloidogyne spp.) problems in horticultural crops. In this context, plant resistance (R) appears as the most effective method of control, but the restricted number of cultivated vegetable species with root-knot nematode R-genes...
