The antinematicidal efficacies of exudates of four common weeds: Crotalaria breviflora, Crotalaria juncea, Crotalaria retusa, and Crotalaria spectabilis were carried out against Meloidogyne incognita. The young actively growing seedling of the common weeds were uprooted and taken to the laboratory for analyses. The root exudates of test plants were prepared by growing the young actively growing seedlings in test tubes wrapped with black carbon paper for five days under lighted florescent bulbs. Root exudates of Crotalaria breviflora, Crotalaria juncea, Crotalaria retusa and Crotalaria spectabilis exhibited nematicidal properties against the Meloidogyne incognita. The effects varied with concentrations of the exudates (P<0.05) using analysis of variance (ANOVA). The effects also differed among test plants with Crotalaria retusa topping in terms of reduction in nematode population. This was followed by C.breviflora, C.juncea and C.spectabilis respectively. The results thus confirmed that all the test plants are potentially viable trap weeds, and can be used for the control of Meloidogyne incognita and should be employed as such.
