Core Overview

Trichoderma fungi belong to the Ascomycota phylum. Their colonies are usually fluffy and initially white. After producing spores, they turn green or other colors. They are not a single species but a genus that contains several important species, such as Trichoderma harzianum, Trichoderma viride, and Trichoderma clavatum, etc. They are natural enemies of many plant pathogenic fungi (especially soil-borne pathogenic fungi).

Mechanism of Action (Multifunctionality and Strong Parasitism)

The mechanism of action of Trichoderma fungi is very active and diverse, which is the key to their efficient disease control:

Strong Parasitism

Recognition and Attraction: Trichoderma fungi can sense the presence of pathogenic fungal hyphae and grow towards them.

Wrapping and Attachment: The hyphae of Trichoderma fungi will tightly wrap around the hyphae of the pathogen.

Penetration and Destruction: Trichoderma fungi will form attachment branches similar to "suckers" and secrete cell wall-degrading enzymes (such as chitinase, glucanase), penetrate and dissolve the cell walls of the pathogen, and then absorb its nutrients until it is killed.

Antagonistic Action

Antibiotic Action: Trichoderma fungi can produce various antibacterial metabolites, such as trichodermin, glaucomycin, and green bacterin, which directly inhibit or kill pathogenic fungi.

Competitive Action: Similar to bacteria, Trichoderma fungi can quickly occupy space and compete for nutrients (especially carbon sources), inhibiting the growth of pathogenic fungi.

Induction of Systemic Resistance

The colonization of Trichoderma fungi can activate the plant's defense system (such as salicylic acid and jasmonic/ethylene signaling pathways), enabling the plant to develop systemic resistance to subsequent pathogen invasion throughout the plant.

Promoting Growth and Soil Improvement

Promoting Growth: Trichoderma fungi can produce plant hormones, promoting seed germination, root development, and plant growth.

Improving Soil: Their mycelial networks help form soil aggregates and increase soil permeability.

Degradation of Toxins: Some Trichoderma strains can degrade toxins and self-toxic substances produced by pathogenic fungi.

Main Target Diseases and Applications

Trichoderma fungi mainly control soil-borne diseases and some leaf diseases caused by fungi, and their disease control spectrum is very broad.

Soil-borne fungal diseases:

Diseases caused by Fusarium: such as wilt disease, root rot disease.

Diseases caused by Nectria: such as damping-off disease, sudden stand disease.

Diseases caused by Phytophthora: such as damping-off disease, root rot disease.

Diseases caused by Microdochium: such as white root rot disease.

Diseases caused by Phytophthora: such as Phytophthora root rot disease, damping-off disease.

Above-ground diseases: They also have certain control effects on gray mold disease, downy mildew disease, powdery mildew disease, etc.

Application methods:

Soil treatment: Root irrigation, trench application, soil mixing, are the main methods.

Seed treatment: Sowing mixture or coating.

Seedling cultivation: Mixed into the seedling substrate.

Spraying: Used for controlling diseases on the above-ground parts.

Composting treatment: Adding Trichoderma can accelerate the composting process and inhibit the pathogenic bacteria within it.

Key Features

Broad-spectrum and highly effective

It has a wide range of efficacy against various pathogenic fungi.

Active attack

Its "heavy parasitism" mechanism enables it to actively seek out and destroy pathogenic bacteria, resulting in a more lasting and stable effect.

Multiple mechanisms

Combining parasitism, antagonism, competition, and induction of resistance, making it less likely to develop resistance.

Promotes growth and soil improvement

It also has the effect of promoting plant growth and improving soil structure.

Environmentally safe

Safe for humans, animals, birds, bees, and the vast majority of beneficial organisms.

Usage Notes

Avoid mixing with chemical fungicides: Absolutely not to be mixed with broad-spectrum fungicides, especially carbendazim, mancozeb, or thiophanate-methyl, or to be used consecutively within a short period. These fungicides will directly kill the Trichoderma fungi. It can be mixed cautiously with some biological pesticides or specific low-toxic chemical fungicides, but it needs to be tested first.

Use in advance: As a preventive fungicide, it must be used before or at the early stage of the disease occurrence to gain time for the establishment of a dominant Trichoderma population.

Create an appropriate environment: Trichoderma fungi prefer warm, humid, organic-rich, slightly acidic to neutral soil. When applying, avoid high temperatures and strong light.

Pay attention to product compatibility: If mixed with other microbial agents (such as Bacillus), the compatibility needs to be understood to avoid mutual inhibition.

Technical requirements for use:

o Soil moisture maintained at 60% or more, ground temperature > 15℃;

o Cannot be used with copper preparations or fungicides within < 7 days of each other.

Storage and transportation: In a cool, dry place (≤ 25℃), sealed, protected from moisture and high temperatures.

Shelf life: 12 months.
