Streptomyces Lydicus Biofungicide for Citrus

As citrus production moves toward more sustainable farming practices, biological crop protection products have become an essential part of orchard management. Streptomyces lydicus biofungicide is a living microbial product developed to protect the rhizosphere by promoting beneficial microbial activity and suppressing soil-borne plant pathogens through natural biological mechanisms.

Unlike conventional fungicides that directly target pathogens with chemical active ingredients, Streptomyces lydicus functions by establishing itself around citrus feeder roots. After application through soil drenching, drip irrigation, or fertigation, it colonizes the rhizosphere and competes with harmful microorganisms for nutrients and colonization sites. It also produces naturally occurring antimicrobial metabolites that help suppress important soil-borne pathogens such as Phytophthora, Fusarium, Rhizoctonia, and Pythium.

Because Streptomyces lydicus works preventively, applications are most effective before severe disease pressure develops. Early establishment of beneficial microorganisms allows the root zone to develop a healthier microbial balance, reducing opportunities for harmful pathogens to dominate the soil environment.

Some of the key advantages of using Streptomyces lydicus biofungicide in citrus orchards include:

• Supports healthy feeder root development
• Promotes a balanced rhizosphere microbial community
• Helps suppress important soil-borne pathogens
• Suitable for preventive biological disease management
• Compatible with drip irrigation, fertigation, and soil drenching
• Supports sustainable and environmentally responsible farming practices
• Integrates well into Integrated Disease Management (IDM) programs

Since Streptomyces lydicus is a living microorganism, maintaining favorable soil conditions is important. Moist, well-drained soils with adequate organic matter provide a better environment for microbial establishment. Avoid prolonged waterlogging, severe soil compaction, and incompatible chemical applications that may reduce microbial viability.

For broader biological support, Streptomyces lydicus is commonly integrated with Trichoderma, Bacillus subtilis, Bacillus velezensis, Pseudomonas fluorescens, Azotobacter, Azospirillum, phosphate-solubilizing bacteria (PSB), potassium mobilizing bacteria (KMB), zinc-solubilizing bacteria, and mycorrhizal fungi. These beneficial microorganisms contribute to a diverse rhizosphere, efficient nutrient cycling, and improved long-term soil fertility.

The product is suitable for orange, lemon, mandarin, sweet lime (mosambi), lime, grapefruit, and pomelo orchards and can be incorporated into both conventional and organic farming systems, subject to local regulations and product certifications. Regular preventive applications during planting, active root growth, pre-flowering, before the rainy season, and post-harvest help establish stable microbial populations that support long-term orchard health.

Whether used alone or as part of a comprehensive biological program, Streptomyces lydicus biofungicide provides citrus growers with a sustainable approach to maintaining healthy roots, improving soil biology, and supporting consistent fruit production.
