Biotechnological potential of bacteria from genera Bacillus Paraburkholderia and Pseudomonas to control seed fungal pathogens.

ABSTRACT: 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 seedlings. 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
