Trichoderma Spp.: A Biocontrol Agent for Sustainable Management of Plant Diseases

Traditional methods for controlling plant diseases and increasing yields, such as chemical pesticides, herbicides or fertilizers are not environmentally friendly because they often contain aromatic groups or methylated and ethylated substances that have signi icant negative effects on the environment.Long-term usage of chemical pesticides can poison water, pollute the atmosphere and occasionally leave dangerous residues that can encourage the growth of particular resistant organisms.Trichoderma spp.are mostly asexual fungi found in rotting wood and all types of agricultural soils.Its hostile behavior demonstrates that they parasitize a variety of soil-borne and foliar diseases.Recent research demonstrates that the fungus functions as a biocontrol agent.These reactions are a crucial component of its biocontrol strategy.It is currently employed in sustainable disease management methods to control plant diseases.In addition to controlling diseases, Trichoderma species also promote plant growth and root development (biofertilizer) and activate the defense mechanisms of plants.Some strains have been demonstrated to colonize root surfaces with vigorous and long-lasting colonization after penetrating the epidermis.Biological control plays a very important role in plant disease management. Biocontrol mechanisms of Trichoderma spp.:Biocontrol agents that are effective against fungal phytopathogens include Trichoderma species.They can exert their in luence indirectly by vying for resources and space, altering the environment, or fostering plant development, plant defense systems and antibiosis or they can exert their in luence directly through mechanisms like mycoparasitism (1, 16, 12).These are some examples of the mechanisms
