Application of Pseudomonas Strains for Biocontrol of Commercial Crops Susceptible to Plant Pathogens: A Review

Abstract

Indiscriminate use of chemicals as fertilizers and pesticides gives rise to substantial harm to the environment and ecosystem along with animals and humans. More importantly, to replace such hazardous agrochemicals, many biological solutions are available in nature which is present in the form of microorganisms having the capacity to promote plant growth substantially. Pseudomonas play a major role in plants like inducing systemic resistance, colonizing plant roots or tissue interior, helping in modulating plant hormone levels, biological control of pathogens and more over regulating the growth-related genes in plants. The fluorescent pseudomonads belong to plant growth-promoting rhizobacteria (PGPR) and many strains of pseudomonas are well known to enhance plant growth promotion and decrease the severity of many diseases. Biocontrol strains of pseudomonas in plant bioassays synthesize one or more several antibiotic compounds. In vitro, these antibiotics have been proven as inhibitory compounds and have exhibited active responses for plant health management in field conditions. The current study mainly relies on the effective use of Pseudomonas spp. as a potential biocontrol agent for the biological control of many diseases in agriculture and horticultural crops.
