AbstractCuadra R., X. Cruz, and J. L. Fajardo. 2000. The use of short cycle crops as trap crops for the control of root-knot nematodes. Nematropica 30:241-246. The effect of short cycle crops such as lettuce ( Lactuca sativa ) and radish ( Raphanus sativus ) to suppress the soil population densities of Meloidogyne incognita Race 2 was investigated in concrete microplots containing an organic soil mix (60% red ferralitic soil and 40% cow dung) in Havana, Cuba. Lettuce and radish crops were grown for 32 and 30 days respectively at high and low initial nematode densities. Thirty to 32 days after planting, plant root systems were completely removed from the microplots to prevent nematode reproduction in those roots and consequent nematode increase in soil. Ten percent and 6% of the lettuce and radish roots, respectively, contained mature females with egg masses. Averages of 2 160 and 21150 J2/m2 were found in the roots of lettuce plants (45/m2) at the lowest and highest infestation level of the
