Prevent & Suppress Damaging Diseases With This Biological Fungicide!

Due to its outstanding effectiveness, this classic biofungicide has been in demand since it first came it market in Finland in 1990. It contains the mycelium and spores of Streptomyces Strain K61, a naturally occurring bacterium derived from Sphagnum peat. It thrives in the root zone and controls some of the most destructive of plant pathogens, including damping-off, wilt and root diseases like Alternaria, Rhizoctonia solani, Fusarium, Phytopthora and Pythium.

3-Way Mode of Action:

  1. It rapidly colonizes plant roots, displacing the pathogenic fungi there and depriving it of nourishment.
  2. Acts as a hyperparasite by disrupting, and ultimately breaking down, the cell walls of the pathogens.
  3. Produces metabolites that constrain the plant pathogens but encourage the plant's defense mechanisms and promote healthy growth.
Additional Benefits of Mycostop:

  • Approved for organic horticulture and agriculture.
  • Disease protection lasts for weeks, but the long-lasting impact will be healthier plants and bigger yields.
  • Compatible with IPM (Integrated Pest Management) programs.
  • It poses no risk to beneficials and there is no risk of resistance being built up.
  • Restricted Entry Interval (REI) of 4 hours.
For best results, Mycostop should be used preventatively. However, it can be used for an infestation; in which case, it should be applied at a higher rate and more frequently. Streptomyces Strain K61 will live in the rhizosphere and keep working for several weeks.
