AbstractTwo experiments were conducted in 1994 in Martinique to compare the efficacy of short-term rotations on the population decline of Meloidogyne incognita and Rotylenchulus reniformis associated with vegetables and various plants. Tomato, weeds, Tagetes erecta, Mucuna pruriens cv. utilis or Brachiaria decumbens were grown, or soil was left in clean fallow, for a three-month period just before planting a crop of lettuce. For M. incognita, the greatest population decline was observed after M. pruriens and T erecta (87% for both crops), while R. reniformis declined most after M. pruriens (86%). The leguminous forage plant, M. pruriens exhibited the best vegetative growth, soil coverage and weed competivity. The use of M. pruriens cv. utilis as a rotation crop may provide a practical and environmentally safe means for growers to suppress population densities of both M. incognita and R. reniformis prior to the cultivation of susceptible short-term vegetable crops.
