Developed from a naturally occurring bacteria, Streptomyces griseoviridis, Mycostop WP is a preventative product that thrives in the rhizosphere for several weeks and provides effective control on a wide range of pathogens including damping-off caused by various fungi, such as Alternaria and Rhizoctonia solani; and wilt and root diseases caused by FusariumPhytophthora and Pythium. When applied as a drench or spray, the dried spores and mycelium of the Streptomyces culture in Mycostop WP germinate and begin to grow on and around the plant root system. This creates a biological defense against seed and soil-borne pathogens, giving your plants a strong start for vigorous growth and development. Streptomyces deprives pathogenic fungi of space and nourishment by colonizing plant roots, where it also acts as a hyperparasite, disrupting cell walls of pathogens and producing metabolites that further inhibit and disrupt these pathogens.  

  • Organic & 100% natural
  • Based on a naturally occurring, live bacterium (Streptomyces sp. strain K61) that readily colonizes roots for extended protection.
  • Use on all crops such as medicinal herbs, vegetables and ornamentals
  • Can be used simultaneously with nematodes and other biological control organisms, compatible with most IPM programs (see Compatibility Guide below)
  • Control or suppression of many root rot and wilt pathogenic fungi, such as  Pythium, Fusarium, Alteraria, Phomopsis, Phizoctonia, Phytophthora and Botrytis
  • Ideal for Hydroponics, solves most root rot issues
  • Works equally well in organic, mineral and artificial growing media, and field soils
  • Easy application by drench, surface spray or through hydroponic delivery
  • No known risks for resistance due to multiple modes of action
  • Safe to apply, regardless of plant maturity/stage
  • Non-phytotoxic
  • Leaves no toxic residues

Mycostop WP is used by growers for disease caused by Pythium, Fusarium, Rhizoctonia, Alternaria, Phomopsis, and to a lesser extent for Botrytis and Phytophtora.  Mycostop WP has particularly good activity against Fusarium, and is increasingly used as a seed treatment for Pythium, Fusarium, and other seedling pathogens.  

Mycostop WP has been shown to increase plant vigor and yields even in the absence of obvious root pathogen activity, as the Streptomyces produce plant root stimulating hormones that benefit plant health overall.

    Saved my Aerogarden crop!

    Posted by Whitney E on 23rd Feb 2022

    Aerogarden is a small hydroponic garden for home cultivation of leafy greens, herbs, and other small vegetables and fruits like peppers and tomatoes. We kept having a problem where the plants would germinate and grow well for a few weeks, but would then wilt and suffer from root rot which would eventually kill them. We suspect this is Pythium, and after talking to VivaGrow we tried adding Mycostop to the Aerogarden water which worked perfectly! The roots are bright white and healthy compared to the brown and slimy appearance they used to have. The plants grow faster too. Leafy vegetables will take off like a rocket with Mycostop protecting their roots! Mycostop also helps with water and nutrient uptake, we have to add water to our Aerogardens almost every day now which is a sign of healthy plants. A tiny little bit of this is all that's needed every time you change the water/nutrients, 1/20 of a gram. We used half of the included scoop (each scoop is 1/10 gram for 1 gallon of Mycostop prepared) for our 6 place Aero gardens which hold about a 1/2 gallon of water. So that means a 2 gram packet is enough for 40 applications! We mixed 1/2 of the scoop mentioned above in 1/2 gallon of water and shook it up as recommended for a few minutes. Once the Mycostop powder was dissolved we added this mixture to the Aerogarden reservoir. We then let the fresh mixture circulate around the plants for 24 hours before adding plant food as recommended by VivaGrow for hydroponics. We do this every 2 weeks as recommended by Aerogarden. Really easy and it works!

    We have a humidity problem that can make propagation difficult. Mycostop will help with most rot problems.
