Scopulariopsis brevicaulis mold

Scopulariopsis brevicaulis is a common soil-dwelling fungus recognized in agriculture as a potential plant pathogen. While primarily a saprotroph, it can become an opportunistic parasite, causing significant damage to weakened plant tissues, particularly in moist and poorly ventilated environments.

The fungus affects a wide variety of plant species, ranging from cereal crops to horticultural vegetables. It is particularly notorious for colonizing seeds during storage and invading the root systems of seedlings in greenhouses, where high humidity levels create ideal conditions for its proliferation.

Symptoms of an infestation typically include the appearance of a characteristic buff or yellowish-brown powdery growth on the plant parts. Affected tissues may soften and become necrotic, which often leads to "damping off" in young plants and significant crop loss in storage facilities.

Development and spread are primarily driven by high moisture levels and warm temperatures between 25°C and 30°C. The pathogen persists in the soil and on crop residues, disseminating via airborne conidia or contact with contaminated tools, soil particles, or infected packaging materials.

Effective management requires a multi-faceted approach, emphasizing prevention through strict environmental control and sanitation. Seed treatment with appropriate fungicides is essential for protection before planting, while maintaining dry, well-ventilated storage environments remains the primary defense against storage decay.

• Maintaining low humidity in storage.
• Fungicidal seed treatments.
• Sanitation of greenhouse substrates.
• Crop rotation strategies.
