Resumo: | ABSTRACT: Recognized as prominent among the principal pests of tomato crop, the root-knot nematode (Meloidogyne incognita) has generated much study with regards to control methods. This study aimed to assess the efficiency of biological products in decreasing the M. incognita population in tomato. Four experiments were conducted under greenhouse conditions. Two of these experiments had the purpose to determine the efficiency of NemOut™ (Bacillus subtilis + B. licheniformis + Trichoderma longibrachiatum), and the other two to assess the efficiency of other different biological products in M. incognita management. Tomato plants of the cultivar Santa Cruz Kada Giant were inoculated using 2000 eggs and J2 of M. incognita. In the first two experiments doses corresponding to 0, 4, 6, 8 and 10kg ha-1 of NemOut™ were applied after inoculation. In the second study, the treatments consisted of the use of biological products containing different other biocontrol agents. Assessments were made at 45 and 65 days after inoculation (DAI) to evaluate plant height, fresh shoot and fresh root weigh, gall index and egg mass index, population density and reproduction factor (RF). The NemOut™ doses reduced the M. incognita population density and RF at 45 DAI. The agent Pochonia chlamydosporia showed greater efficiency in controlling M. incognita on tomato. Biological products and the different doses of NemOut™ had no influence on the tomato plant development.
