Biological control of pest using antagonistic microorganism Murugan Ahiladevi National Pulses Research centre, Vamban, Pudukkottai District 622 303 Online published on 27 August, 2019. Abstract Fungi and bacteria showing ability of biological control of destructive diseases are distributed in many fungi. Fluorescent Pseudomonas Beaveria bassiana is most effective bacteria for biological control plant diseases. Pseudomonads enhance plant growth parameters, and hence, they are called as plant growth-promoting rhizobacteria (PGPR). Those PGPR are known to control wide range of phytopathogens like fungi, bacteria, viruses, insect pests and nematodes, through bio-control mechanism (competition, or antagonism). These bacteria induce systemic resistance in the host plant, thereby controlling invading pathogens. For management of pest and diseases of crop plants, applications of mixtures of PGPR formulations gives better results, than the use of individual strains. The fungal and bacterial antagonist, showing various modes of action, especially rhizosphere colonization, antibiotic production and induction of systemic resistance would certainly be potential bio-control agent for management of pests and diseases of crop plants.
