Bio-Control
Biological control agent refers to the use of natural or modified organisms, that reduce the incidence or severity of diseases caused by plant pathogens. These agents induce enhanced resistance against a pathogen, compete for space and nutrients with pathogens, interact by antibiosis mechanism, secrete antimicrobial agents against pathogens, and kill and invade pathogen. It exhibits an antagonistic activity toward a particular phytopathogen.
01
Trichoderma viride
Trichoderma viride is an antagonistic ability towards plant pathogenic fungi and they have received considerable attention as biocontrol agent of soil-borne plant pathogens. The production of secondary metabolites by Trichoderma strains also shows great variety and application potential in the medicinal field. Trichoderma viride seems to be an inexhaustible source of antibiotics by transformation of the acetaldehydes gliotoxin and viridin.
02
Pseudomonas fluorescens
Pseudomonas fluorescens is a common Gram-negative, rod-shaped bacterium. It belongs to the Pseudomonas genus. The Fluorescent Pseudomonads belong to plant Growth Promoting Rhizobacteria (PGPR) and play a major role in the plant growth promotion, induced systemic resistance, biological control of pathogens. Many strains of Pseudomonas fluorescens are known to enhance plant growth promotion and reduce the severity of various diseases.
03
Bacillus subtilis
The genus Bacillus comprises 377 species. It’s a Gram-positive, rod-shaped bacteria found in soil and the gastrointestinal tract of ruminants. Their ability to form endospores, their diversity in physiological properties, as well as their capacity to produce numerous antimicrobial compounds favor their ubiquitous distribution in soil, aquatic environments, food and gut microbiota of arthropods and mammals.
