Boost in soil fertility
Soil fertility depends on a number of factors, among which soil infestation by pathogenic fungi plays a significant role. Their undesirable influence is well known to every agronomist and grower; the presence of harmful fungi in the soil is a common reason why a particular crop fails in a given location, even though the overall conditions are favourable for its cultivation. Pathogenic soil fungi belong to a number of different genera (e.g., Fusarium, Sclerotium, Sclerotinia and Thielaviopsis) and fungicide protection of the above-ground part of the plant is ineffective against them. The question therefore arises: what options do we have in these cases?
As a possible solution to this problem, we would like to introduce our product KESTOM®, which contains the antagonistic fungus Trichoderma atroviride. This Trichoderma strain is amongst the plant-friendly soil microflora, and increasing its share of the rhizosphere leads to the suppression of pathogenic fungi and a significant reduction in their abundance. Trichoderma in KESTOM® is registered as strain KE100M, it is the exclusive property of MONAS Technology, s.r.o., and is stored in the Collection of Microscopic Fungi in Prague.
DAY 4 DAY 11 DAY 21 In vitro experiment with T. atroviride and S. cepivorumThe timed sequence of an inoculated petri dish shows how Trichoderma atroviride (green mycelia at the top of the dish) fully outgrows the pathogenic fungus Sclerotium cepivorum over a period of three weeks.

As early as in the first year of the experiment, we can observe a marked difference in the vigour of plants grown in infected soil (2 kg/ha of KESTOM® was applied to the treated sample). However, this result is not definitive and we can expect the difference to deepen further in the upcoming years.

Mode of action
Trichoderma atroviride is a natural enemy of other fungi in the soil. Not only does it compete with them for nutrients and space, it can also actively reduce their viability. Its secondary metabolites include, among others, atroviridins, which have fungistatic effects. In addition, mycoparasitism has been documented in T. atroviride: this species purposefully attacks other soil fungi as a means of its own nutrition. For this purpose, it produces endochitinases and exochitinases, which disrupt the chitin structure of all parts of pathogenic fungi. As a result, the trichoderma mycelium aggressively outgrows other fungi – their mycelia, reproductive organs, spores and sclerotia.
Recommended applications
-
Option. 1: as a soil disinfectant
In this case, it is sufficient to apply KESTOM® to the soil after harvest and till it in.
-
Option. 2: in synergy with bacterial products ("the double punch")
• KESTOM® is applied to the soil after harvest. It should be tilled in and left to work for at least 3 weeks when it is warm and humid.
• In the following crop, bacterial rhizosphere products are applied by spraying in the field or in planters - depending on soil type. -
Option. 3: as direct crop-root support
Apply KESTOM® to the soil, either to the crop before sowing or at sowing/planting of the crop.
Available packaging
- KESTOM® is packaged in 0,5 or 1 kg plastic backs or in 2 kg plastic container..
- Pour the content into the spreyer and mix.
- It is recommended to add an adjuvant with KESTOM® for better dispersion of spores in the water.
Tank Mixes
- KESTOM® is not to be mixed with pesticides.
