Rhodophyllus

Rhodophyllus (now commonly recognized under the genus Entoloma) is a genus of fungi that includes species capable of acting as opportunistic plant pathogens. These fungi primarily target the subterranean parts of plants, causing decay and interfering with the vital nutrient uptake processes necessary for crop development and yield production.

The disease is caused by basidiomycete fungi that dwell in the soil. These pathogens are highly persistent, capable of surviving for long periods on organic debris, which makes the management of contaminated soil a significant challenge for professional agronomists and landscape managers.

Target crops include a wide range of fruit trees, ornamental shrubs, and certain vegetable species. The pathogen is particularly active in environments where soil structure and aeration are compromised, leading to physiological stress in the host plants and making them more susceptible to fungal colonisation.

Symptoms typically present as a steady decline in plant vigor, leaf chlorosis, and stunted growth. Infected plants may exhibit signs of wilting even when soil moisture appears adequate, indicating significant damage to the root system which prevents efficient water transport throughout the vascular tissues.

• Excessive soil moisture and poor drainage
• High levels of organic matter in the soil
• Repeated cropping on the same site
• Extended periods of cool, wet weather

To combat this disease, it is essential to prioritize improved soil drainage and the use of healthy, disease-free nursery stock. Chemical control options include systemic fungicides applied to the root zone, while biological control agents, specifically beneficial fungi like Trichoderma, can be highly effective in outcompeting the pathogen and restoring soil health. Regular monitoring of root health is critical for early detection and mitigation of outbreaks.
