Koppert’s biological fungicide prevents fungal pathogens from being the first to colonise the soil after disinfection
Under glass, disinfection is an efficient method to eliminate pathogens from the soil, but it has a disadvantage: after the disinfection, the soil becomes an inert medium. All the harmful micro-organisms will have been eliminated, along with those that have a beneficial function.
To start up the new crop cycle with healthy soil and strong roots, Koppert recommends applying Trianum immediately after disinfection. And the fact is that when the soil has lost all its microbiological life, there is a serious risk for the pathogen organisms to be the first in colonising it again.
Trianum has been shown to be highly effective, since it contains an exclusive strain of the beneficial fungus Trichoderma harzianum that is quick to develop in all types of soil and in a wide range of temperatures. It grows between 8º and 34º C, with pH levels between 4 and 8.5. The strain, which is only produced and marketed by Koppert, is one of the few that is authorised for use in ecological farming because it is 100% natural, it does not leave any residue on the fruit or the leaves, it is compatible with most fungicides, fertilizers and insecticides/acaricides, and it has no safety period or MRL.
The biological fungicide has a double function: it protects the plant and prevents soil diseases produced by pathogens such as Fusarium, Sclerotinia, Rhizoctonia and Phytium. And it feeds the plant as it helps to improve nutrient metabosalisation.
Trianum is available in two formulas. Trianum-P (in powder format) is applied in the last irrigation phase with an approximate dose of 1 kg/Ha. Trianum-G (in pellet format), is particularly indicated for mixing with substrates and applying directly on each row of plants with a dose of 30 to 50 g for every 1,000 plants.
Trianum’s 5 weapons
After application, Trianum grows very quickly along the roots to protect the plant using five biological mechanisms. It competes for space, as it quickly forms a physical barrier along the surface of the roots, preventing pathogens from becoming established. It competes for nutrients and does not leave any food resources for the pathogens. It develops micro-parasitism, as the Trichoderma strain grows around the pathogens and produces enzymes that break down their cell walls, disabling them and eliminating them. Lastly, it promotes a healthier root system, with more root hairs, improving water and nutrient absorption. The result is a stronger and more uniform crop, particularly when the plants are grown in adverse conditions.
