Rhizobacteria (PGPR) and Trichoderma Strengthens all cultures starting at the roots in a biological way Bactiva® is a water dispersible soil inoculant, which strengthens the plant root and enhances the resistance. The product is of a powdery texture and contains a highly potent strain of Bacillus subtilis and several species of the beneficial fungus Trichoderma, which strengthen plants in a natural way. Bactiva® is a rooting agent that stimulates the growth of roots through bacteria that produce plant hormones (Gibberellins, Cytokinins), such as Bacillus megaterium and Pseudomonas fluorescens. The bacteria and Trichoderma stimulate strong root growth throughout the entire growing period. In addition, they are indispensable tools during the plant germination phase or during the restoration of damaged roots. The bacteria fix nitrogen and make chemically inaccessible phosphorus soluble. Thereby they provide elements, which plants cannot take up otherwise. Biostimulants excite the biological activity of the soil. In association with the microbial ingredients, they enhance the level of cell division and lateral bud development, whereas the aging process of plant tissues is delayed.
