| Les nématodes à galles (Meloïdogyne spp.), aussi parfois appelés anguillules, sont des ravageurs du sol particulièrement difficiles à éliminer en agriculture biologique comme en agriculture conventionnelle. Ils provoquent des dégâts considérables sur les cultures maraîchères mais aussi sur les plants des pépinières fruitières et ornementales. Cette fiche technique présente le ravageur et quelques méthodes de lutte actuelles ou à l'état de recherches. |

| A trial was established in 2003, in Southern France, to assess under organic farming conditions the effect of top irrigation with sprinklers on potato yield, but also to evaluate side effects on epidemics, with a focus on late blight (Phytophthora infestans L.). Two varieties, one susceptible (Charlotte) and one with a good level of resistance to late blight (Eden), have been planted. Three irrigation regimes have been applied : no irrigation [NO], reduced or optimized irrigation [OPT] and irrigation according to usual grower practice [NORM]. Irrigation had no effect on foliar late blight development. For both varieties, commercial yield in the non-irrigated plots was significantly lower (16,36 t.ha-1) than in the OPT and NORM plots (resp. 26,12 t.ha-1 and... |
