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.

    Natural Streptomyces Therapy

    Posted by Bill on 5th Aug 2021

    Wonderful compliment to most any organic feed program, for use on most any plant you can find. Soil drench with this product and then foliar spray for maximum results, and use before the plants are sick like a vaccine.

    Root Zone

    Posted by H B on 14th Jan 2019

    If your system is hurting from a root zone problem THIS will fix. It wont make you a better grower but it will help with slime and root rot and most root zone problems I have come to see.I use as a top rinse 5g pack on a 12 plant system. I have turned dark brown dead slimy roots into a harvest using this. Happy growing!!
