Cephalotrichum infection

Cephalotrichum infection is a fungal disease caused by species of the Cephalotrichum genus. These fungi are typically known as molds that colonize weakened, damaged, or decaying plant tissues. While often functioning as saprotrophs, they can act as opportunistic pathogens, causing significant quality loss in stored agricultural produce and young seedlings.

This pathogen affects a wide range of plants, including cereals, legumes, and various fruit-bearing vegetables. It is particularly notorious for its impact on seed viability, as it often colonizes the surface of seeds, leading to decay even before the seeds have a chance to germinate. High-density storage areas are the most common environments where this fungus proliferates.

Visual symptoms of the disease are characterized by the development of dense, dark-colored mycelial growth that often looks like a velvet-like coating on plant parts. In the context of seed infection, the outer layer becomes covered in dark spores, leading to reduced germination rates. In field crops, it may result in damping-off of seedlings and poor plant establishment.

The development of Cephalotrichum is heavily influenced by environmental factors, primarily high humidity and stagnant air. The fungus spreads effectively through airborne conidia or physical contact with contaminated tools and storage containers. Once established in a storage facility, the pathogen can spread rapidly if humidity levels exceed the recommended thresholds.

Effective management strategy relies on strict post-harvest and pre-planting practices. Key protection measures include treating seeds with appropriate fungicides, ensuring proper drying and ventilation of harvested grains, and sanitizing storage facilities to prevent spore buildup. Crop rotation and maintaining soil health also contribute to reducing the inoculum level in the field environment.
