Streptomyces lydicus strain WYEC 108

Streptomyces lydicus strain WYEC 108 is a naturally occurring soil-borne actinomycete bacterium used as the active ingredient in broad-spectrum biological fungicides. This specific strain was originally isolated from the plant rhizosphere and is renowned for its ability to suppress a wide variety of phytopathogenic fungi while simultaneously promoting plant root development and overall vigor.

This agent functions primarily as a biofungicide. Its mechanism of action involves competitive colonization of the root zone, effectively starving out harmful pathogens. Furthermore, the bacteria produce specific enzymes, such as chitinases and glucanases, which degrade the cell walls of fungal pathogens. By establishing a symbiotic relationship with plant roots, it also helps the plant absorb nutrients and water more efficiently.

Products containing this strain are widely used on various crops, including vegetables, ornamental plants, and cereal grains. The primary applications target soil-borne diseases such as root rots, Fusarium, Pythium, and powdery mildew. It is highly effective when used as a seed treatment, a dip for transplanting seedlings, or as a soil drench during the planting process.

Successful application requires maintaining adequate soil moisture to ensure the bacteria thrive and colonize the root environment effectively. This biofungicide is environmentally friendly, does not induce resistance in pathogens, and is fully compatible with organic farming practices. Users should avoid tank-mixing it with harsh synthetic fungicides, which may inhibit the growth of the beneficial bacterial population.

• Active colonization of the plant root system.
• Biostimulation for faster seed germination.
• Strong efficacy against complex root rot diseases.
• Safe for beneficial insects and non-toxic to humans.
• Suitable for integrated pest management (IPM) programs.

When applying the product, standard safety precautions for biological pesticides should be followed. It is recommended to use personal protective equipment, such as masks and gloves, to avoid inhalation or skin contact with high concentrations of spores, which might trigger sensitivities. To maintain the viability of the strain, the product should be stored in a cool, dry place away from direct sunlight.
