Trianum can hold its ground

The Trichoderma harzianum T-22 fungus in Trianum is incredibly hardy. It can be used in combination with many other products, and even the use of most chemical products generally has little negative effect on the effectiveness of Trianum. Despite this, an approach free of chemicals should always be the starting point.

Pesticides can, directly or indirectly, have a negative influence on beneficial micro-organisms: have effect on spore germination or mycelium growth. It is, therefore, important to check whether a combination of biological and chemical agents is a wise choice. Does the combination boost both agents, or does it inhibit one or the other?


Trianum can be used in combination with most fungicides, insecticides, acaricides, biostimulants, and liquid fertilizers. This demonstrates that the Trichoderma fungi in Trianum are quite persistent. Especially once the fungal mycelium has 'conquered' the roots of a crop, there is little that moves it.

Please note that when using the water-soluble variant of Trianum, it is important not to use products containing chlorine or hydrogen peroxide in the drip irrigation lines before, during, and after treatment to give the Trichoderma fungi a chance to develop fully.
