Abstract
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
