“…Some elements found in the biofertilizers, mainly in Biozyme TF ® , have been reported as important for plant protection against the attack of pathogens. They may have direct or indirect action on such pathogens (Shaukat & Siddiqui, 2003;Rumiani et al, 2016).…”

The aim of the present study was to assess Pratylenchus zeae control in sugarcane by using biological nematicides in association, or not, with biofertilizers. Sugarcane pre-sprouted seedlings were transplanted to pots and inoculated with 2 mL of a solution containing 1000 P. zeae in the planting furrows, treated with the combinations based on two biological nematicides, three biofertilizers, and their respective controls, and one absolute control (without treatment or nematode). Results evidenced that biological nematicides based on Trichoderma harzianum and Bacillus spp., when applied alone, promoted reductions in the nematode population of 33.81 and 31.62%, respectively. For nematodes per gram of root, the reductions were 34.67 and 25.38%. On the other hand, biofertilizers efficiency in the nematode reproduction presented variations. However, all treatments reduced nematode penetration in the sugarcane root system, with reductions varying from 31.17 to 53.21%. The same was observed in the mortality test, where nematode mortality ranged from 38.95 to 81.10%. Nematicidas biológicos associados a biofertilizantes no manejo de Pratylenchus zeae em cana-de-açúcarRESUMO: O objetivo do presente estudo foi avaliar o controle de Pratylenchus zeae em cana-de-açúcar utilizando nematicidas biológicos associados ou não a biofertilizantes. Mudas pré-germinadas de cana-de-açúcar foram transplantadas para vasos e inoculadas com 2 mL de solução contendo 1000 P. zeae nos sulcos de plantio, tratadas com as combinações baseadas em dois nematicidas biológicos, três biofertilizantes e as respectivas testemunhas, e um controle absoluto (sem tratamento ou nematoide). Os resultados evidenciaram que os nematicidas biológicos à base de Trichoderma harzianum e Bacillus spp., quando aplicados isoladamente, promoveram reduções na população de nematoides de 33,81 e 31,62%, respectivamente. Para nematoides por grama de raiz, as reduções foram 34,67 e 25,38%. Por outro lado, a eficiência dos biofertilizantes no controle da reprodução do nematoide apresentou variações. Mas, todos os tratamentos reduziram a penetração do nematoide no sistema radicular da cana-de-açúcar, com reduções variando de 31,17 para 53,21%. O mesmo foi observado no teste de mortalidade, cuja mortalidade do nematoide variou de 38,95 a 81,10%.
