Our Bio-fungicide for plants, in particular, contains the power of the fungus Trichoderma harzianum at a spore load of 2 x 10⁶ CFU/g; an ideal concentration to ensure that the spores can successfully germinate and actively seek damaging species of fungi that cause root rot, damping off and wilt diseases. The specific strain contained in this product is the result of the mixture of the most desirable traits of several naturally-occurring subspecies, here condensed for the ultimate ease of use and benefit of the grower. It is at the same time an inoculator of beneficial fungi and an organic fungicide, designed to have a long-lasting to permanent effect, if the conditions for the survival of the Trichoderma fungi are met.
