Biocontrol Agent
Several strains of Trichoderma have been developed as biocontrol agents against fungal diseases of plants. The various mechanisms include antibiosis, parasitism, inducing host-plant resistance, and competition. Most biocontrol agents are from the species T. harzianum, T. viride and T. hamatum. The biocontrol agent generally grows in its natural habitat on the root surface, and so affects root disease in particular, but can also be effective against foliar diseases.

Famous quotes containing the word agent:
“The most durable thing in writing is style, and style is the most valuable investment a writer can make with his time. It pays off slowly, your agent will sneer at it, your publisher will misunderstand it, and it will take people you have never heard of to convince them by slow degrees that the writer who puts his individual mark on the way he writes will always pay off.”
—Raymond Chandler (1888–1959)
