Entoloma pleopodium

Entoloma pleopodium (Entoloma pleopodium) is a fungal organism that, while primarily recognized as a soil-dwelling saprophyte, can manifest as a plant pathogen under specific environmental conditions. Within the field of agronomy, it is noted for its ability to impact root health and compromise the vitality of various ornamental and vegetable crops.

The causal agent is a fungus that belongs to the Basidiomycota phylum. As a soil-borne pathogen, it infects the root system, causing degradation of plant tissues. The disease development is insidious, often affecting the stability of the plant's vascular system through the colonization of the primary root tissues by its mycelial network.

A wide range of crops is susceptible to this infection, particularly those grown in greenhouses or in poorly drained agricultural soils. The fungus thrives in environments with high organic content and moisture, where it can easily switch its ecological strategy to parasitize weakened host plants that suffer from poor environmental management.

Visible symptoms include systemic wilting of foliage, stunted growth, and visible root necrosis. If examined closely, the root system often appears discolored or brittle. The spread of the fungus is accelerated by constant humidity and inadequate soil aeration, which are essential factors for the successful colonization of new healthy root systems.

The economic impact of this pathogen is significant due to potential yield loss and the difficulty of eradicating the fungus once it is established in the soil. To mitigate the risk, the following protection and prevention measures are recommended:

• Improving soil drainage to prevent stagnant water in the root zone.
• Using certified, disease-free seedlings for planting.
• Applying targeted fungicides to suppress mycelial growth in the soil.
• Practicing proper crop rotation to break the pathogen's life cycle.
• Ensuring optimal plant nutrition to enhance the natural resistance of the host crops.
