Potential of Sahelian native shrub materials to suppress the spiral nematode Helicotylenchus dihystera /Chapuis Lardy, Lydie Diakhate, S. Djigal, D. Ba, A. O. Dick, R. P. Sembene, P. M. /Masse, Dominique Biological control Helicotylenchus dihystera millet intercropping native evergreen woody shrub nematicidal activity Pennisetum glaucum Pihostkma retkulaturn plant-parasitic nematode Sahelian agrosystem management soil organic amendment spiral nematode western Africa Pearl millet (Pennisetum glaucum) is a drought -tolerant cereal commonly grown for grain and fodder in arid areas throughout the world. Senegalese millet fields are infested with Helicotylenchus. The native evergreen woody shrub Pihostigma retic ulatumi s widely distributed in sub-Saharan Africa. Its coppiced residues are used by small farmers as mulch in crop fields. The shrub's nematicidal effect on the spiral nematode Hehmohdenchus dihystera was evaluated in a pearl millet pot experiment. The abundance of nematodes decreased by 64% after application of either leaf powder or a pulverized mixing of leaves and stems, suggesting the use of aboveground materials of P reficulatum as a potential nematicide. The results show promise for use of a local resotu're. by subsistence farmers in the Sahel. Further research is needed on application to fully develop this approach as a biopesticide. 2015 text https://www.documentation.ird.fr/hor/fdi:010066035 fdi:010066035 Chapuis Lardy Lydie, Diakhate S., Djigal D., Ba A.
