The active ingredient in Trianum is Trichoderma harzianum, strain T-22. This strain is the most frequently studied Trichoderma strain in the world. The first studies of this specific strain date from the 1980s and were carried out by Gary Harman of Cornell University in the United States. Scientists all over the world have demonstrated that this strain can make a good contribution to the reduction of soil-borne diseases. Plant-strengthening effects have also often been observed. There are dozens of publications under the name of Gary Harman about this specific strain. These have clarified which mechanisms form the basis of the effects that can be achieved with T. harzianum, strain T-22.

Research
Koppert has been carrying out research on Trianum in many countries since 1999. Research is also carried out by independent bodies. The research looked at both the effect on soil-borne diseases and the plant-strengthening effects.

Results
Trianum has a number of mechanisms (see effects), which can produce various results.
Research has demonstrated that the regular application of Trianum makes it possible to achieve the following results:

• reduced incidence of disease
• greater yields
• greater fresh weight and dry weight of above-ground and underground plant parts
• better flower development

In most cases, a better developed root system and more uniform crop growth are observed. This occurs mainly when the cultivation conditions are less than optimum.

Specific research results are available for a large number of crops. These can be consulted for the crop concerned under the heading applications.
