摘要

Influence of nematicidal activity of either Jatropha curcas or J. gossypiifolia as a intercropping with sunflower cv. Giza 1 (1, 2, 3 and 4 jatropha plants per pot) for control of Rotylenchulus reniformis was carried out under a greenhouse conditions . The nematode final population and the rate of reproduction were significantly (P≤ 0.01) affected by the number of both Jatropha species when grown with sunflower together. Also, a negative relationship was found with the seedlings number of both jatropha species and both the final nematode population and rate of nematode reproduction. The lowest nematode final population and rate of reproduction were determined at the highest number of both jatropha plants (4 plants per pot). The highest value of nematode reproduction (5.5) was found on sunflower plants grown alone, while, the lowest values (0.5 and 1.6) was found on sunflower plants grown with four plants of J. curcas and J. gossypiifolia; respectively. Eventually, J. curcas plants were more effective against the reniform nematode, R. reniformis than J. gossypiifolia did. Therefore, this type of control is considered easy, pollution-free and inexpensive.
