The extreme complexity of interactions that can occur in the rhizosphere is highlighted and some potential areas for future research in this area are discussed briefly. Multiple microbial interactions involving bacteria and fungi in the rhizosphere are shown to provide enhanced biocontrol in many cases in comparison with biocontrol agents used singly.

Get FREE solutions to all questions from chapter MICROBES IN HUMAN WELFARE. The significance of plant growth promotion and rhizosphere competence in biocontrol is also considered. Watch complete video answer for Microbes As Biocontrol Agents of Biology Class 12th. Whenever possible, modes of action involved in each type of interaction are assessed with particular emphasis on antibiosis, competition, parasitism, and induced resistance. The interactions of bacteria used as biocontrol agents of bacterial and fungal plant pathogens, and fungi used as biocontrol agents of protozoan, bacterial and fungal plant pathogens are considered. Urszula Wachowska1, Katarzyna Kucharska1, Magorzata Jdryczka2. This review examines the microbial interactions that can take place in the rhizosphere and that are involved in biological disease control. Microorganisms as Biological Control Agents against Fusarium Pathogens in Winter Wheat. Generally, saproptrophs or biotrophs such as mycorrhizal fungi grow in the rhizosphere in response to this carbon loss, but plant pathogens may also develop and infect a susceptible host, resulting in disease. Controls phyto-pathogens Rhizoctonia sp, Pythium sp, Fusarium sp, etc.The loss of organic material from the roots provides the energy for the development of active microbial populations in the rhizosphere around the root.Environmental friendly, non-hazardous to the human beings, livestock and wildlife.Produces toxic metabolites like gliotoxin, viridian and trichodermin, which controls harmful fungal pathogen.It controls plant pathogens by generating competition for nutrients and space for survival.Effective control of soil borne fungal pathogens.Trichoderma viride – Colony Forming Unit: ≥ 2 x 10 6 per gram Benefits Scheepmakera and Jan van de Kassteeleb a Downloaded by RIVM, Jacqueline W.A. The pathogen eventually dies and gets eliminated from the soil. 10, October 2011, 1225 1242 RESEARCH ARTICLE Effects of chemical control agents and microbial biocontrol agents on numbers of non-target microbial soil organisms: a meta-analysis Jacqueline W.A. It grows faster than disease causing fungi, coils around the pathogen, penetrates and kills the fungus. It controls soil borne plant diseases like damping off, wilt, root rot and collar rot. Fungus Biocontrol Agent for Soil Plant PathogensīIO-T is a talc based formulation containing the strains of Trichoderma viride.
