Non-Chemical Control of Armillaria mellea Infection in Prunus persica: A Sustainable Approach

Introduction: Armillaria mellea is a persistent fungal pathogen causing root rot in various trees, including peaches (Prunus persica). Controlling this infection is challenging as fungicides are largely ineffective, and eradication is difficult. A recent study explores non-chemical control methods, offering insights into sustainable agricultural practices.

Key Findings:

• Planting Hole Size: Larger planting holes (2m³) increased peach tree survival rates compared to standard smaller holes (P=0.07).
• Organic Amendments: The addition of fresh yard waste to large holes significantly enhanced tree survival (P=0.04) by promoting microbial activity antagonistic to Armillaria mellea.
• Trichoderma Application: Spraying planting holes with Trichoderma spp. did not significantly affect survival, likely due to sufficient native populations in the yard waste.

Biological Control and Soil Management: The American Phytopathological Society emphasizes the importance of soil microbial diversity in controlling plant pathogens. Incorporating organic amendments like yard waste may foster beneficial fungi, including Trichoderma, which can suppress Armillaria mellea populations.

Conclusion & Practical Implications: This study suggests that mechanical soil disturbance, coupled with organic amendments, can improve tree survival in Armillaria-infested soils. Future research should explore larger-scale applications and additional microbial interactions.
