Sudozone is a biofungicide-bionematicide-biobactericide based on Pseudomonas fluorescens. It acts on hyphae of plant pathogens by enzymatic, antagonistic and antibiotic actions. It controls and prevents nematodes that invade roots and give access to pathogenic fungi to enter into roots. It exerts PGPR activity also by producing fluorescent pseudomonads that chelates with soil nutrients, thus making the nutrients available to the plants.
