FAQ

Why should I use Trianum preventatively?

Fungal spores are present in every substrate in a greenhouse or outdoor plot. These fungi can quickly establish themselves on the roots of young plants. Keep a few steps ahead of other fungi by using Trianum as early as the propagation phase.

Can I also use Trianum for the first time in an older crop?

It is possible to apply Trianum at a later stage of cultivation. Application during propagation is preferable; see also "Why should I use Trianum preventatively?".
First, reduce the disease pressure in the rhizosphere using a suitable product in order to facilitate the establishment of Trianum.

Why do I need to repeat applications?

Due to attacks by micro-organisms, the concentration of Trianum will decline over time. By applying a top-up dose (see diagram), the high concentration of spores on the roots can be maintained.

How much water do I need to use when watering from above?

Do not use too much water, as this would result in the spores being flushed out.
Watering in soil-based crops:

propagation: 2.5 to 5 litres of water per m²
cultivation: 5 to 10 litres of water per m²

Can I apply fungicides while using Trianum?

Fungicides are generally not harmful for Trianum. However, wait for 3 to 10 days before application. See Koppert’s summary of side effects for specific information.

Can I mix fungicides with Trianum?

Koppert advises against mixing Trianum with fungicides/soil fungicides.

Can Trianum also be applied in an NFT system?

We have only limited experience with the application of Trianum in NFT systems. However Trianum is seen in good quantities on the roots of the plants when used in these systems.
