PRO-MIX® BRK BIOFUNGICIDE™ is a medium weight growing medium. This peat and bark based formula adds weight, reduces water retention and ensures optimal balance between air and water also it will resist to long-term compaction and improves container stability. This medium has been enriched with a biofungicide (Bacillus Subtilis) that prevents root diseases. These bacteria colonize developing root systems, and suppress disease-causing organisms, such as Pythium, Fusarium and Rhizoctonia, which attack root systems. The bacteria also act as a biostimulant developing with the growing root system. A vigorous root system is then established, resulting in more uniform plant stands after transplanting in the field and in greater crop yields.
