Resumo: The management of nematode infested areas includes several measures, among which chemical nematicides are the most used. However, since their use is associated with environmental impacts, researches with biocontrol agents have acquired a greater importance. This study aimed to evaluate the performance of Bacillus subtilis + B. licheniformis, when applied to the planting furrow, on nematode control and its effects on sugarcane yield. Five experiments were carried out in infested areas, with four treatments: control - no nematicide; carbosulfan 700EC 4 L ha-1 - standard treatment; B. subtilis + B. licheniformis at 0.16 kg ha-1 and 0.20 kg ha-1. Carbosulfan was more efficient in controlling the nematodes, reducing the populations at least four months after planting. The treatments with B. subtilis + B. licheniformis were more effective in the control of Meloidogyne javanica, when compared to Pratylenchus. The plots treated with carbosulfan produced 11 % more than the control. There was no difference between the B. subtilis + B. licheniformis doses, in relation to yield. The plots treated with the biological product produced 5 % more than the control. KEYWORDS: Bacillus subtilis, Bacillus licheniformis, Meloidogyne, Pratylenchus.

No entanto, visto que o uso desses produtos está associado a impactos ao ambiente, pesquisas com produtos biológicos têm adquirido grande importância. Objetivou-se avaliar o desempenho de Bacillus subtilis + B. licheniformis, quando aplicado ao sulco de plantio, no controle de nematoides e os efeitos na produtividade de canaviais. Foram conduzidos cinco experimentos em áreas infestadas, com quatro tratamentos: testemunha - sem nematicida; carbosulfan 700EC 4 L ha-1 - tratamento padrão; B. subtilis + B. licheniformis a 0,16 kg ha-1 e 0,20 kg ha-1. O carbosulfan foi mais eficiente no controle dos nematoides, reduzindo as populações pelo menos até quatro meses após o plantio. Os tratamentos com B. subtilis + B. licheniformis foram mais efetivos no controle de Meloidogyne javanica do que de Pratylenchus. As parcelas tratadas com carbosulfan produziram 11 % mais que a testemunha. Não houve diferenças entre as doses de B. subtilis + B. licheniformis, em relação à produtividade. Parcelas tratadas com o produto biológico produziram 5 % mais que a testemunha.
