Dora Agri is the professional supplier, manufacturer & exporter of the Trichoderma harzianum based products in China. We devoted to optimizing Trichoderma fermentation technology in the past five years to produce high-activity Trichoderma fungus spores. It’s your first option to buy trichoderma products with a competitive price from Dora Agri.
What's Dora RootGuard
Dora RootGuard is the trichoderma harzianum based biocontrol agent on soil micro-environment, disease control & root system growth. The brightest spotlight, it has an excellent ability to eliminate damaging fungal pathogens in soil, and form a nature defensive bond to Guard and stimulate roots for plants.
Now Trichoderma products are applied as bio-fungicide, bio-fertilizers, root growth-promoting fungi, and compost additive.
Application Mode: Pre-planting applications to seed, post-pruning treatments, incorporation in the soil during seeding or transplant, watering by irrigation, or applied as a root drench or dip.
Suitable Plants: Fields, Greenhouses, Nurseries, Horticultural Plants, Fruits, Trees, and Ornamental Crops.
Trichoderma Harzianum Uses in Agriculture
1. Improve Soil Condition
Trichoderma harzianum products have outstanding soil adaptability in soil, control soil-borne pathogens and help soil build a stable crumb structure, which is porous & full of nutrition and preserve moisture and fertility.
Improve soil problems such as soil salinization, hardening, and acidification conditions. Reduce heavy metals & organic pollutants. Significantly improve soil micro-environment and fertility.
2. Bio Diseases Control
After we used the Dora RootGuard, it will produce mycelia to grow along with the roots, will form a physical bond on the surface of the plant’s root system, establishing itself in the rhizosphere(root zone) and protects the roots against soil-borne diseases.
3. Stimulate Root Growth
Trichoderma harzianum promotes crop growth in three main ways:
- Control the fungus which causes root rot
- Reduces the physical stress on the crop and makes it grow better
- Secrete organic acids and natural growth hormones to promote the growth of crop roots system
Researches show that Trichoderma harzianum is one of the most effective microbes to colonize the roots.
4. Increase Plant Resistance Ability
Dora RootGuard is capable of systemically activating plant defense mechanisms. In actual use, it can increase the ability of the plant against abiotic stresses such as drought, salinity, high temperature.
5. Use as Compost Additive
The synergistic effect of compost and T. harzianum facilitated higher seedling growth in compost-based planting. Trichoderma can enhance disease suppression in moderately suppressive composts. Compost disease suppression can be part of a more sustainable agricultural system through careful management and development of compost quality guidelines.
Mode of Action
1. Biocontrol Mechanism
Trichoderma product’s mechanisms for control & against pathogens diseases including Nutrient & Space Competition, Antibiosis, Parasitism, Inducing host-plant Resistance.
2. Soil Remediation Mechanism
Leading Trichoderma harzianum Production Technology
Compared with traditional solid fermentation technology with more contaminating microorganisms and short survival time. Our Trichoderma series used the latest technology of liquid fermentation, with the benefits of low contaminating microorganism rate and longer survival time.
