Is pseudomonas a biocontrol agent?

Species of the genus Pseudomonas embodies an attractive biocontrol agent because of their catabolic adaptability, their outstanding root-colonizing abilities, and their capacity to produce a wide range of antifungal metabolites.

What are bacterial biocontrol agents?

Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biological control agents of weeds include seed predators, herbivores, and plant pathogens.

What is used as biological control of plant disease?

Biocontrol organisms work by competing with the pathogen for space and nutrients, by parasitism or predation, by inducing the plant’s natural defense system, and/or by the production of antimicrobial substances (antibiotics like streptomycin). Often several mechanisms function together to make an organism effective.

Is Trichoderma a biocontrol agent?

Trichoderma spp. are the most widely used fungal biocontrol agents against fungal diseases of pulses, grapes, cotton, onion, carrot, peas, plums, maize, apple, etc. Trichoderma spp. grow very fast and can produce polysaccharide-degrading enzymes, so it can be grown on a large number of substrates.

How are microbes used to control plant growth?

There has been many recent studies on the use of microbial antagonists to control diseases incited by soilborne and airborne plant pathogenic bacteria and fungi, in an attempt to replace existing methods of chemical control and avoid extensive use of fungicides, which often lead to resistance in pla …

How are Streptomycetes a biocontrol agent for plants?

Streptomyces spp. and their metabolites may have great potential as excellent agents for controlling various fungal and bacterial phytopathogens. Streptomycetes belong to the rhizosoil microbial communities and are efficient colonizers of plant tissues, from roots to the aerial parts.

How are microbial antagonists used to control plants?

There has been many recent studies on the use of microbial antagonists to control diseases incited by soilborne and airborne plant pathogenic bacteria and fungi, in an attempt to replace existing methods of chemical control and avoid extensive use of fungicides, which often lead to resistance in plant pathogens.
