Use of bacillus-based biocontrol agents for promoting plant growth and health

Abstract

In the wake of an increased attention on the environment-friendly biopesticide and the increasing market demand for organic produce, Bacillus-based biocontrol agents have been found to exhibit an excellent performance for promoting plant growth and health. They produce different biologically active compounds that affect both pathogens and plants in a variety of ways. In addition, the strains of Bacillus species are stable in natural environment due to their ability to form heat- and desiccation-resistant spores. There are many Bacillus strains, including B. subtilis, B. cereus, B. polymyxa, B. megaterium, B. amyloliquefaciens, B. pumilus, and B. thuringiensis that have been reported for their capacities to protect plants from pathogens or pests and to promote plant growth. A review of this genus on biological control could help for the development and application of the Bacillus-based biocontrol agent into biopesticidal products and to improve plant health and crop yields.
