Developed from a naturally occurring bacteria, Streptomyces griseoviridis, Mycostop is a preventative product that thrives in the rhizosphere for several weeks. When applied as a drench or spray, the dried spores and mycelium of the Streptomyces culture in Mycostop germinate and begin to grow on and around the plant root system. This creates a biological defense against seed and soil-borne pathogens.

  • Effective against a wide range of seed and soil-borne pathogens
  • Compatible with most chemical pesticides for use in an Integrated Pest Management program
  • Ecocert certification
  • Growth promotion
  • No residues on edible crops
