Abstract

RUIZ, SE et al. In vitro antagonistic activity of Bacillus subtilis strains isolated from soils of the Yucatan Peninsula against Macrophomina phaseolina and Meloidogyne incognita. Phyton (B. Aires) [online]. 2014, vol.83, n.1, pp.45-47. ISSN 1851-5657.

The antagonistic activity of native Bacillus subtilis strains from Yucatán peninsula soils were evaluated on two soilborne pathogens. Bacillus subtilis cbck36 and cbrf24 caused more than 60% inhibition of colony growth in Machophomina phaseolina. Cell-free culture filtrate of B. subtilis cbr24 were active against second-stage juveniles (J2) of Meloidogyne incognita (LC₅₀ 25.8% v/v).

Keywords : Soil-borne pathogens; Cell-free filtrate; Rhizobacteria.
