A. Sawadogo et al., Impact of agronomic factors on Meloidogyne spp. populations and their mostcommon parasites in Sahelian vegetable cropping systems, NEMATOLOGY, 2, 2000, pp. 895-906
Nematode surveys were carried out in vegetable producing areas in two Sahel
ian countries, Burkina Faso and Senegal. Correspondence analysis between ag
ronomical factors and populations of Meloidogyne spp. revealed that vegetab
le susceptibility to nematodes was not the only factor responsible for soil
and root infestations. Population densities would more readily depend on c
ropping systems (previous crops, often flooded lowlands vs well drained upl
ands). Natural occurrence of nematode-parasitic microorganisms (nematophago
us fungi and Pasteuria penetrans) in upland agrosystems was observed and co
uld be used together with cultural practices in an IPM approach.
