Trichoderma viride is a highly effective beneficial soil fungus that is an important part of modern sustainable agriculture. It is often referred to as a "bio-fungicide" because it provides an additional layer of natural protection against soil-borne pathogens like Fusarium and Rhizoctonia, by colonizing the root systems of plants. In addition to providing additional protection from disease causing organisms, this fungus aids in stimulating the plant's immune system to develop its own natural defense mechanisms known as induced systemic resistance, thereby allowing crops to tolerate and cope with environmental stresses such as drought and excessive salinity.
Trichoderma can be applied to virtually all types of crops including cereals, legumes, fruit crops, and decorative ornamental plants. The application of Trichoderma benefits from enhanced soil microbial activity through stimulating the degradation of organic matter, resulting in more nitrogen, phosphorus, and potassium (the basic building blocks for healthy plant growth) becoming available to the plant. The end result is stronger root growth and increased yields from Trichoderma, representing a powerful biological alternative to synthetic fertilizers and chemical pesticides.
Understanding Trichoderma viride in Agriculture
Trichoderma viride, a beneficial fungus found in soil, is used in agriculture to create healthy plants, improve soil fertility, and control pathogens. This fungus is important to sustainable farming because it supports plant growth, builds stronger root systems, and increases microbial activity in the soil.
Farmers worldwide are using trichoderma for plants to achieve increased yields with less reliance on chemical fungicides. To use trichoderma to grow healthy crops and manage soil sustainably, it is important to understand the biology and function of trichoderma.

- Improving Fertility of Soils - Trichoderma viride increases the amount of active enzymes and provides increased diversity of the soil microbes.
The Science Behind Trichoderma viride Effectiveness
The mechanism of action for Trichoderma viride is based on its ability to stimulate the plant's natural defense system and ability to also act as a root colonizer for promoting plant growth. There are many ways to utilize the Trichoderma fungi to enhance crop health and optimize soil management.
Mode of Action of Trichoderma Fungus
It produces enzymes and metabolites that prevent the growth of pathogens attacking crops and additionally stimulate plant growth. To support plant growth, Trichoderma viride produces the following compounds that inhibit the development of a wide spectrum of soil borne pathogens.
This process is accomplished by:
- Cellulose-digesting, chitin-digesting, beta-glucan-digesting enzymes produced by Trichoderma viride degrade the cell walls of pathogenic fungi.
- Trichoderma viride releases a number of different secondary metabolites that inhibit pathogen development in the soil
- Trichoderma viride improves the microbial activity in the soil allowing plants to utilize greater amounts of critical nutrients (nitrogen and phosphorus) that would normally be unavailable to them.
The combination of these two processes, controlling pathogenic fungi and promoting plant growth, enables Trichoderma viride to be extremely beneficial for all major crop types.
Antagonistic Activity Against Plant Pathogens
One of the major advantages of using Trichoderma viride is that it provides an antagonistic effect on many plant pathogens, such as Fusarium wilt, Rhizoctonia, and Pythium, thereby providing natural protection for crops.
The Mechanism by which T. viride works includes:

Soil Application Techniques for Trichoderma for Plants
Trichoderma is at its most effective when it has been mixed with 100kg of moist organic compost and kept in a cool, dark location for one week (to allow for multiplication). Once the enriched mix has been created, it can be broadcast (spread) over the entire field or used to fill seedling holes during soil preparation. Maintain the moisture level of the soil and refrain from using any chemical fungicides
- The Enrichment Process with Organic Compost. Incubate or "push" the mixture of compost and Trichoderma for a minimum of 7 days to ensure maximum fungus growth.
- Field Application. Once your mix is fully prepared, evenly spread the Trichoderma mixture over the soil before planting your crops.
- Drenching. You may also apply an immediate drench of the liquid suspension at the base of the plant to protect its roots.
- Nursery Planting. The enriched Trichoderma mixture can be applied directly to the seedling bed when planting out young seedlings.
Compost and Organic Matter Enrichment
range of microbes and their associated nutrients will be increased,
supporting the production of strong, healthy crops when used in
conjunction with sustainable/organic farming practices.
Compost Enrichment Benefits:
- Decomposition will occur quicker than without Trichoderma.
- Increased soil microbial diversity, and therefore greater fertility of the soil.
- Increased available nutrients for crops, naturally.
- Improved soil structures (water and air retention). Application
Method:
- Apply Trichoderma mycelium powder or granules to compost/organic matter as it is being created.
- Maintain moisture and aeration for optimum microbial activity.
- Apply the enriched compost to the crop fields for healthier plants and to produce more disease-resistant crops.
Best Practices for Using Trichoderma viride
The Trichoderma viride fungus can effectively enhance plant growth, treat soil-borne diseases, and improve soil structure, making it a valuable tool for producers interested in environmentally friendly solutions to their farming needs. However, to get the most from Trichoderma, producers should be aware of the best practices regarding its application, handling, and storage. Understanding how Trichoderma interacts with soil, fertilizers, and the environment will help producers achieve optimum health for their crops, while simultaneously supporting sustainable yields and maintaining soil quality.
Compatibility with Fertilizers and Inputs
When using trichoderma fungus on crops, it is imperative that you are mindful of its use with other inputs and fertilisers, and that you take the necessary precautions to keep from adversely affecting the effectiveness of trichoderma. Some chemicals can adversely affect or eliminate trichoderma.
