Testou-se a susceptibilidade de dez esécies florestais a meloidogyne javanica (Treub, 1885) Chitwood, 1949. Faveiro (Parkia platicephala Benth.), imbiruçu (Pseudobombax simplicifolium A. Robyns J.), imburana de cheiro (Torresia cearensis Fr. all) e algaroba (Prosopis juliflora D.C.) são hospedeiros susceptíveis. Angico (Anadenanthera macrocarpa Engl.) e leucena (Leucaena sp) mostraram-se não susceptíveis, enquanto que aroeira (Astronium urundeuva Engl.) pau d' arco (tabebuia impetiginosa Mart.) sabiá (Mimosa caesalpinipholia Benth.) e violeta (Dalbergia cearensis Ducke.) mostraram-se imunes. Nas espécies imbiruçu e imburana de cheiro, o nematóide produziu ramificações do xilopódio. Não se constatou efeito do nematóide na sobrevivência de mudas de nenhuma das espécies estudadas. |

Fungal pathogens are important determinants of plant dynamics in the environment. These pathogens can cause plant death and occasionally yield losses in crops, even at low initial densities in the soil. The objective of this study was to select and evaluate fungal antagonistic bacteria and to determine their biological control capacity in soybean eedlings. A total of 877 strains from the genera Pseudomonas, Bacillus, and Paraburkholderia/Burkholderia were screened, and their antagonistic effects on fungi frequently found in seeds were evaluated using four methods: quadruple plating, paired culture confrontation, strain containment, and inoculation of soybean seeds. The experimental design was completely randomized, with three replications for the first three methods and five replications in a 3 × 9 factorial scheme for the fourth treatment. The strains with the highest biotechnological potential were inoculated into soybean seeds to evaluate the biological control of fungi that attack this crop at germination. Seventy-nine strains presented some type of antagonistic effect on the tested fungi, with two strains presenting a broader antagonistic action spectrum in the seed test. In addition to the antagonistic potential, strains BR 10788 and BR 11793, when simultaneously inoculated or alone, significantly increased the seedling dry matter mass, and promoted the growth of soybean seedlings even in the presence of most fungi. Thus, this study demonstrated the efficiency of the antagonistic activity of these strains in relation to the target fungi, which proved to be potential agents for biological control.
