description

Fusarium wilt of melon, caused by Fusariumoxysporum f.sp. melonis (F.o.melonis),is still a major problem for growers. Aresearch programme was therefore developpedincluding 23 partners (VASCUlég).Analysing the situation revealed that thebioagressors are adapting, particularlyF.o.melonis race 1.2 whether it be on its ownor associated with other pathogens. Molecularcharacterisation of the F.o.melonisstrains shows strong genetic diversity.However, new sources of resistance to therace 1.2 of F.o.melonis were identified. Thisresult must be used in combination with acertain number of other complementarytechniques tested within the framework ofthe project, such as the cropping system,biofumigation, companion plants, biocontrolagents and plant defence stimulators.
