INOQ mycorrhiza FAQs

No, on the contrary. Soil with high nutrient content can hinder the development of mycorrhiza.

Mycorrhiza clearly improves soil quality as it replenishes the soil fauna. At the same time, you should pay attention all aspects of soil quality (avoiding compaction, paying attention to crop rotation, covering the soil, avoiding erosion, etc.). The plant becomes more well-connected to the soil thanks to the mycelium. The plant’s uptake of nutrients and moisture are improved, as well as the consistency of the soil. On sloped land, the stability of the soil will also be improved; plants can tolerate an incline 5° greater if the vegetation is well mycorrhised.

In plant tubs and balcony boxes: yes

Vegetable gardens and farmland: yes, due to tilling

Healthy garden: an annual application is recommended but may not necessarily be essential, depending on the conditions in winter.

The plants become more tolerant to disease and pests. You can think of the mechanism as similar to a vaccine: when a plant comes into contact with the mycorrhizal fungus, the defence mechanisms of the plant are driven into action. This process has a positive effect on the plant’s vitality. Additionally, potential entry points for harmful organisms in the roots of the plant are already occupied by the mycorrhiza fungus. However, mycorrhiza cannot be considered a protective substance for plants, and does not foster resistance to disease or pests in the plant.

The production of mycorrhizal fungi must be undertaken with great care. We produce our products in Germany, and pay attention to the natural living conditions of the fungi when manufacturing, in order to provide customers with vital fungi. Our comprehensive quality control guarantees a valuable product for your application.

Scientific testing processes are used to ensure effectiveness and to guarantee the special qualities of the product. We developed this quality control process with other manufacturers of inocula in Germany and Europe. It is carried out according to the guidelines of the voluntary agreement of the interest group “Applications of arbuscular mycorrhiza fungi in horticultural practice” from 02/12/1997.

A test is carried out to determine the quantity of mycorrhiza fungi in an inoculum (MPN test), the effectiveness is tested, and a macro array analysis is conducted, in order to eliminate phytopathogens.

The criteria for quality and the product safety measures are published in data sheets. These are available for download as a PDF at our website Mycorrhiza Products (Product declaration).

All products have a shelf life of 2 years when stored in a dry and dark place between 4 and 15 ° C

In private gardens, no fungicides, pesticides or other chemical plant protection substances should be used.

For professional applications, we give the following advice:

Pesticides consist of extremely varied chemical agents, which can have negative, neutral, or positive effects on the development of mycorrhizal fungi. If you introduce mycorrhiza products, it is still possible to apply fungicides to combat pathogenic fungi. Harmful fungi differ from symbiotic fungi, and therefore do not experience the same effect from fungicides. Additionally, the majority of fungicides are applied to leaves, and therefore do not come into contact with the mycorrhizal fungi, meaning that they have no effect on the mycorrhiza symbiosis.

So choosing the correct fungicide allows you to apply both products simultaneously, without limiting the function of the mycorrhiza fungi.

We have investigated the effects that different pesticides have on the development of endo- and ectomycorrhizal fungi. If you would like more information on this topic, please feel free to contact us.

You can read about the effects of pesticides on endomycorrhizae in the following publications:

, you can find a list of the most popular tree species and which type of mycorrhiza should be used with them.

Mycorrhiza is only present in healthy soil. With new soil applications or purchased substrates such as compost, there is no longer any mycorrhiza present. The soil structure is disturbed and therefore an application of mycorrhiza is recommended.
