Streptomyces cinnamoneus

Streptomyces cinnamoneus is a species of actinomycetes frequently found in soil ecosystems. In an agronomic context, it is regarded as a microorganism capable of exhibiting both antagonistic and pathogenic properties regarding various agricultural crops. This pathogen belongs to the actinobacteria group, which primarily inhabit the rhizosphere of plants.

This microorganism can affect a wide range of crops, including root vegetables and various horticultural plants. The primary damage occurs during periods of high soil moisture, when bacterial colonies actively develop on plant residues and the root system, disrupting the normal nutrient uptake of the plant.

Symptoms of infection include stunted growth, yellowing of the foliage, and the appearance of specific lesions on the underground parts of the plant. Rotting of fine root hairs is frequently observed, leading to mineral deficiencies and a significant reduction in the overall vitality of the crop.

The development of the pathogen is most active at soil temperatures ranging from +20°C to +28°C under high humidity. It spreads easily through contaminated soil, plant debris, farming tools, or irrigation water, maintaining its viability in adverse conditions through the formation of resilient spores.

The economic impact of Streptomyces cinnamoneus stems from reduced crop yields and damaged produce quality. For effective control, it is recommended to practice proper crop rotation, soil disinfection, use certified healthy planting material, and apply biological control agents that suppress the activity of pathogenic strains.
