Application
Trichoderma harzianum can be used to prevent plant diseases caused by pathogens such as Pythium, Rhizoctonia solani, Fusarium, Botrytis cinerea, Rhizopus nigricans and Cladosporium. Its main active ingredient is the Trichoderma harzianum T-22 strain. Trichoderma is a kind of microorganism widely existing in nature. Trichoderma harzianum is the earliest and most widely used strain of Trichoderma. The T-22 strain is an artificially modified strain, which is an artificial hybrid strain obtained by cell fusion technology using T95 and T12 strains as parents. The T95 strain has strong ability to entwine and colonize plant roots, while the T12 strain has strong disease control ability. By combining the advantages of both through cell fusion technology, the T22 strain with excellent root entwining, colonization and disease control capabilities was obtained. At the same time, it inherited the adaptability of its parents to different soil types and can colonize and reproduce well in sandy loam and clayey soil, making the application of T22 more adaptable.
Target diseases: Damping-off, root rot, and other fungal root diseases, as well as gray mold and other leaf diseases.
Product Advantages
Easy to use - Utilizes water-soluble carriers with good dispersion in water, and will not clog spraying or irrigation equipment.
Wide application range - This product is suitable for the root systems of various crops, and can also be used on crop leaves and during harvest and storage periods.
Applicable to multiple treatment methods - It is recommended to use it for seedbed treatment. It can also be used for seed soaking, root dipping, and foliar spraying. It can be applied with fertilizers and water for irrigation or used alone for root irrigation, or for foliar spray treatment.
Economical and environmentally friendly - Using this product can reduce the amount of chemical fungicides, decrease chemical pollution to the environment, lower the resistance of pathogenic bacteria, and thereby reduce the cost of disease control.
Long-lasting effect - When applied to the roots, it can last for more than 3 months. When sprayed on leaves, it can last for 7 to 15 days, reducing the frequency of application and labor input.
Product Features
- Grows around plant roots and forms a "protective shield" to prevent infection by root pathogenic fungi.
- Secretes enzymes and antibiotic substances to break down the cell walls of pathogenic fungi.
- Stimulates root growth in plants, making the root system healthier.
- Has a zero-day safe harvest interval after application and is certified as an organic production material by the Organic Materials Review Institute (OMRI) in the United States.
- Compatible with fertilizers, insecticides, acaricides, herbicides, disinfectants, growth regulators, and most fungicides.
- Suitable growth conditions: pH 4-8, soil temperature 8.9-36.1°C. After symbiosis with plant roots, it can alter the microstructure of the soil to make it more suitable for root growth.
Mechanism of action
Competitive effect: Trichoderma harzianum T-22 can grow rapidly in the rhizosphere and phyllosphere of plants, occupying the sites on the surface of the plant body and forming a protective shield, just like putting boots on the plants. This prevents pathogenic fungi from coming into contact with the roots and leaves of the plants, thereby protecting the roots and leaves from infection by the aforementioned pathogenic fungi and ensuring the healthy growth of the plants.
Application scope
