Trichoderma has always been a member of the soil ecology since the beginning of time. This naturally occurring fungi will continue to provide health benefits to plants long after science proves what it does for plant growth. Trichoderma is composed of many different types of enzymes which support healthy plants and improve soil conditions. This is done through organic means. Because of the many biological benefits of Trichoderma, it is used by farmers today as an organic method of controlling the diseases of crops. Trichoderma has been known to suppress many pathogens, therefore creating room for beneficial bacteria in the soil ecosystem. Beginning with the original observations in soil and progressing to its current global acceptance as a bio-fungicide, every point along the way of Trichoderma's journey confirms its significance in providing resilience for the modern agricultural system.
Introduction: Why Understanding the History of Trichoderma Matters
The Trichoderma species became recognized by agricultural scientists as an important tool in modern farming practices. By understanding the Trichoderma taxonomy, how it has shaped the way farmers, researchers, and agronomists view the role Trichoderma plays when it comes to preventing diseases, promoting better soil health and enabling sustainable practices will allow for greater use and understanding of Trichoderma.
Origins of Trichoderma and Its Scientific Significance
- Trichoderma was first recognized in the 1800's as a common soil dwelling fungus based on early mycological research.
- At that time, Trichoderma was considered to be nothing more than a decomposer that thrived off of organic matter in soil.
- As research continued to develop on Trichoderma, scientists found that it had a unique capacity of suppressing harmful fungal pathogen activity on plants which represents a major step forward in understanding the importance of Trichoderma in agriculture.
Over the years, the classification of Trichoderma has developed as more and more research has taken place using Trichoderma and the classification of the various Trichoderma species based on morphology and behavior was utilized to develop the understanding and significance of Trichoderma for use in agriculture. The early phases of discovering Trichoderma were crucial in shaping how scientists look at the ecological interactions of fungi in soil.
Scientific milestones in the history of Trichoderma include:
- Initial isolation of Trichoderma from soil samples used in agriculture
- Identification of Trichoderma as a fast growing and competitive fungus
- Identification of Trichoderma as an antagonist to select plant pathogens
- Trichoderma has become an important model organism for fungal biology research
Growing Importance of Trichoderma in Agriculture
- Increased agricultural productivity with higher risks of crop disease led researchers to initiate studies of various natural alternatives to fungus preventive chemical products.
- During those investigations, they encountered Trichoderma as an additional, natural protection alternative, which became a catalyst for its eventual development into a commercial-fungicide form.
- Beginning in the mid-to-late twentieth century, extensive testing resulted in Trichoderma-based commercial products used to control fungi that invade crops and cause problems like Fusarium, Pythium, and Rhizoctonia.
Farmers soon began using these products because they were safer for the environment, more cost-effective, and beneficial for long-term soil health.
Some of the reasons that make Trichoderma an important agricultural product:

Discovery and Early Research on Trichoderma Species
Between the time when scientists studied plants and soils as early versions of Trichoderma to its eventual classification as an agricultural Fungicide, a lot of information about Trichoderma has been gathered. Long before it was classified as a Fungicide for use in Agriculture, research of the "competitors" that affected plant growth in fields became an important part of research into soil fungi. The work conducted on the Rhizosphere of plants and the ability of Trichoderma to be effective against both soil pathogens and saprophytic competitors provided the basis for the development of successful alternatives to chemical pesticides.
First Identification and Isolation of Trichoderma
The Term Trichoderma was officially issued in the early 19th century, with the first recorded separation occurring in 1820 and then in later publications. Trichoderma spores are bright green in colour, extremely fast growing in culture, and commonly found in organic composts.
The three major characteristics of Trichoderma that are well established in the scientific
community since its initial discovery and identification are:
1. Spore colour is green
2. Rapid growth compared to many other types of fungi
3. Ability to suppress pathogen(s) (and saprophitic competitors) and promote plant growth through competition for resources in the rhizosphere.
Early Soil Fungi Studies and Mycology Foundations
During the evolution of science as an academic field into what we know today as mycology, mycologists began to examine fungi found in the soil as more than simply decomposers but also as being an active component of crop health. It was during this time that Trichoderma was noted as being uniquely antagonistic towards certain plant pathogens.
Important Research Findings:
- Trichoderma can consume or outcompete detrimental soil fungi
- Trichoderma produces enzymes that degrade the cell walls of other fungal species
- Trichoderma quickly colonizes root zones of plants
- Trichoderma produces or creates natural disease suppression (e.g., root rot)
Historical Classification and Naming of Trichoderma Species
As research continued, it became obvious that Trichoderma does not represent a single organism but, rather, represents a group or genus of organisms that are quite diverse. As research progressed with new technology (e.g., microscopy and, later, molecular techniques) it became possible to accurately classify the different species of Trichoderma.
Key Classification Milestones:
- Early classifications were based on physical characteristics such as the size, shape, and color of Trichoderma spores
- Major species of Trichoderma were identified, such as T. varied and T. harzianum
- Later, species classification changes were made using DNA sequencing to refine species identification
- Recognition has also taken place to identify specific agricultural benefits based on the particular species of Trichoderma that is used.

Since its discovery as being naturally present in agricultural soils, Trichoderma has been subject to experimental and developmental investigations which have provided valuable information leading to its eventual commercialisation as a biofungicide product for use in agriculture throughout the globe. The establishment of Trichoderma as a commercialised biofungicide can be traced back to the research of several pioneering scientists that laid the groundwork that ultimately supported the widespread availability of fungicide Trichoderma products in the world’s agricultural production systems.
Early Mycologists Who Shaped the Field
The first identification of Trichoderma was made in the late 1700's and early 1800's during the development of new classifications for some of the earliest identified soil fungi (myco- and microbiologists).
- Using morphological and spore characteristics of fungi, scientists identified the fungus as Trichoderma and identified it as being an independent genus that frequently occurred in agricultural soils.
- Historically, early researchers had focused their investigations on rapidly growing fungi that produced large quantities of green spores and demonstrated ecological versatility in their ability to inhabit many different types of soil.
- Although it had not yet been appreciated that Trichoderma was an important fungus for agricultural purposes, these early studies were the foundation for documenting the ecological and biological nature of Trichoderma.
The following were initially documented:
- Tharzianum was the first identified species of Trichoderma.
- Trichoderma species are already present in the ∼ 30 % of soils that are presently classified as fertile.
- In documenting the fast rate of growth and aggressive behaviour of Tharzianum, it showed that Tharzianum outcompeted other fungi for resources.
Landmark Studies That Revealed Trichoderma’s Unique Abilities
