The results show that the fungi can act against M. incognita and M. mayaguensis, the most infective species in West Africa but also frequently detected through coffee plantations. They can also control the development of Meloidogyne populations on tomato plants. A cultural practice has been developped using compost blocks in which the fungus was inoculated. In a field experiment, the growth of tomato plants has been increased while the nematode development has been decreased. However, all these experiments have been performed during a short period. In order to enhance the competitivity of the fungus, the fungus can be associated with bacterial isolates, called NHB (Nematophagous Helper Bacteria), which stimulate the fungal activity against Meloidogyne but involve also a depressive effect on other plant parasitic nematodes such as Rotylenchulus reniformis.
