A combination of Streptomyces and Bacillus strains enhances the biocontrol efficacy against phytopathogenic diseases caused by Sclerotinia, Rhizoctonia, and Fusarium.

A combined Streptomyces dioscori SF1 and Bacillus cereus G2 strain achieves over 70% inhibition of major phytopathogenic fungi, boosting plant health and growth.

• Why it matters: Biotic stress from fungal pathogens diminishes crop yields and quality, necessitating eco-friendly solutions to reduce reliance on chemical pesticides and promote sustainable agriculture.
• What they did: The study developed a multi-strain biocontrol agent, SF1+G2, which demonstrated strong antifungal activity, plant growth promotion traits, and induced systemic resistance in multiple crops through laboratory and soil assays.
• The result: SF1+G2 significantly reduced disease severity, enhanced antioxidant enzyme activities, and improved soil nutrients and plant growth, supporting its potential as an effective, eco-friendly biocontrol agent for sustainable farming.
