Effective management of plant-parasitic nematodes affecting yams includes practices that can break the pest cycle from field to store. This study evaluated nematode population changes under cover crop cultivation following a main yam crop. Ten cover crops were planted after the harvest of the yam crop, in six different yam plots under natural nematode(More)
Studies were carried out to determine the nematicidal effect of Tithonia diversifolia, Azadirachta indica, Zanthoxylum zanthoxyloides and Datura metel on Meloidogyne incognita. Nematode eggs and juveniles were exposed to 0 mgkg (control), 25,000 and 50,000 mgkg concentrations of water extracts made 1 1 from the botanicals. Air-dried milled samples of the(More)
