  • Biocontrol mechanism of Trichoderma

    1) Competitive role<br /> Competition mainly refers to the competition between biocontrol agents and pathogens for growth space and nutrition, which is to say, to seize territory. Trichoderma grows fast and has strong vitality. It can quickly occupy the growth space, absorb the needed nutrition, weaken and eliminate other pathogens in the same growth environment.<br /> 2) Hyperparasitism<br /> Hyperparasitism refers to a series of continuous steps of contact, penetration and parasitism. That is to say, Trichoderma will first establish a good relationship with the pathogen through diplomatic means, and then produce hydrolase to degrade the cell wall of the pathogen and kill the pathogen.<br /> 3) Synergetic antagonism<br /> Antagonistic effect refers to the inhibition of growth, reproduction and infection of pathogenic bacteria by Trichoderma through the production of small molecule antibiotics and large molecule antibacterial proteins or cell wall degrading enzymes. In fact, the antagonistic effect of Trichoderma may be a combination of multiple biological control mechanisms at the same time or in sequence.<br /> 4) Induced resistance<br /> Trichoderma can induce host plants to produce defense responses, inhibit the growth and reproduction of pathogens, and induce crops to produce self-defense system to obtain local or systemic resistance. The production of resistance is similar to the principle of vaccination.<br /> 5) Good symbiosis with Probiotics<br /> Because Trichoderma has a good signal recognition system, it has no killing power for non pathogenic bacteria, and can achieve the effect of mutualism.<br /> 6) Promotive effect<br /> Trichoderma can not only control the occurrence of fungal and bacterial diseases, but also increase the germination rate of seeds, the length of roots and seedlings and the vitality of plants.<br />
