Nematodes are phytopathogenic agents that directly interfere with the absorption of water and nutrients by plants, causing losses of up to 60% in production. Its control is hard, as they have a high range of hosts and resistance structures, thus, bio stimulants are a viable alternative, to promote growth and control these organisms. Therefore, this test aimed to evaluate different doses of Bacillus subtilis in response to nematode control, as well as bean development and production.The experiment was conducted in a protected environment in Bauru, state of São Paulo,and the design was completely randomized (DIC), being: T1: the witness, with autoclaved soil and without inoculum and 0.0 mL L-1 of Bacillus subtilis, T2: 0, 0 mL L-1 of Bacillus subtilis, T3: 5.0 mL L-1of Bacillus subtilis, T4: 10.0 mL L-1 of Bacillus subtilis and T5: 15.0 mL L-1 of Bacillus subtilis, T6: 20.0 mL L-1 of Bacillus subtilis, with eight replications. The biological parameters of the culture were evaluated at 45 and 70 days after sowing. Treatments T3 and T4 were able to control and/or reduce nematodes of the genera Meloidogyne spp., Pratylenchus spp. and Helicotylenchusspp, as well as an increase in the evaluated biological parameters.
