Acrisan has been specifically developed to provide pruning technicians with a valid instrument for protecting pruning cuts against the onset of biotic stress. The specific mix of microorganisms in the Biopaver microbial consortium, which belong to different species, intervenes synergistically by activating competition mechanisms. Acrisan is also made up of a mixture of natural polymers that make the formulation resistant, elastic and able to isolate harmful microorganisms while simultaneously providing beneficial microorganisms that promote the formation of a callus, thus increasing natural resistance in plants.
