  • Microorganisms for the treatment of roots:

    Mycorrhizal fungi, Trichoderma and beneficial bacteria (PGPR)

    This section gives answers to frequent questions about the application, efficacy, compatibility, durability, quality and safety of our microorganisms for the treatment of roots.

    How to recognize a "good" biological inoculum?

    A biological product is "good" if it works well at reasonable cost. It is not just "good" because it is cheap or has a high concentration of spores or because the manufacturer makes ambitious promises.

    When choosing between products one should first hear the opinions of other users. It is preferable to start with the treatment of a small area, avoid radical changes and take into account that recommendations might have to be adjusted after gathering first-hand experience.

    How do products that contain microorganisms differ?

    Microbial products vary significantly in their species and strain composition, concentration, manufacturing process, preservation method, and additives. Some products come with large quantities of metabolites that have accumulated during the manufacturing process. They are effective immediately, without the need for the microorganisms to start growing first. In other products, the organisms lose their desirable properties in the course of the production process. In addition, manufacturers differ widely in quality standards and their level of experience with their products under market conditions.

    This is only the beginning of a long list of variations that makes it difficult to objectively compare products with each other. The user should ask how long the products can be stored and whether they can be incorporated in a given crop management system. Can he count on decent technical support? What is the reputation of the brand and its manufacturer in the market? How many other users does he know?

    When faced with the choice between two chemical products, such as two NPK fertilizers or two products based on metalaxyl, the best product is often simply the one with the highest concentration of the active ingredient. When both suppliers have an equal reputation the consumer only has to perform a back-of-the-envelope calculation on price and content. However, a mere comparison of ingredient lists is not sufficient for biological products. A product based on Trichoderma harzianum can be more effective than a competing product that boasts a thousand-fold concentration.

    How can you verify that a product actually contains the spore concentration that is specified on the label?

    Usually it is impossible for the user to examine the spore concentration. He may turn to a state-approved microbiological research outfit. Unfortunately, the reported concentrations often differ widely when splitting a sample into different parts and sending them to several labs. If the user has finally won confidence by receiving similar results by a number of labs, he still cannot be sure that he will receive the same concentration or an equal degree of purity in the following purchase.

    In this situation, the reputation of a brand is crucial. We are concerned about our reputation as a manufacturer and operate a strict quality control system which has assured consistently good results for many years. We invite independent research institutes to apply our quality control procedures, so that our statements are transparent and comprehensible to others.

    How does TNI secure the quality of its products?

    We retain samples for each production run and subject them to quality control. The aim is to determine the number of spores and their ability to germinate by applying generally accepted microbiological methods.

    What is the purpose of the additives that are found in many products that contain microorganisms?

    The spores are attached to small particles of additives which provide them with a food source and help them to get started.

    Critics claim that products with microorganisms are improved by additives such as amino acids, humic acid and seaweed extract, so that a positive effect occurs regardless of whether or not it stems from the organisms.

    In the case of our highly concentrated products only a few hundred grams are usually applied per hectare. However, these small amounts of product contain many spores, almost all of which are able to form a colony and thereby to multiply exponentially. Additives cannot grow and reproduce. Applying a few grams per hectare of sea kelp has a negligible effect on plant growth.
