For the managenent of nematode of nodule of Meloidogyne incognita in plants of Solanum lycopersicum L., it was determined the effectiveness of plant extracts: Ruta graveolens, Eucalyptus spp., Ocimum basilicum, Acacia farnesiana, and Nicotiana tabacum, and as a control fungus Paecilomyces lilacinus 6.5x1013 UFC/g were used. For each treatment were used 5000 nematodes J2 of M. incognita/plant. The extracts were applied per intervals of 10 days in three occasions. The assessed variables were: plant height, performance at 8 cuts and efficiency of the extracts at 20 weeks after the transplant. The results show not significant differences among treatments for the plant height. Regarding the performance with A. farnesiana, it was obtained the highest performance (18.46 kg m-2), followed by P. lilacinus 6.5x1013 UFC/g. with 16.46 kg m-2. Both treatments are statistically different from the treatments, witness (12.91kg m-2), R. graveolens and O. basilicum (13.03 and 13.8 kg m-2) respectively. About the effectiveness for the reduction of the nematode in soil, A. farnesiana reduced it 57%, and P. lilacinum fungus 50.5%. So, the use of extracts is an alternative for the management of nematodes populations of the Meloidogyne gender because they act as repellents and cause them nematodes death.
