Colletotrichum changpingense

Colletotrichum changpingense is a microscopic phytopathogenic fungus belonging to the Colletotrichum genus. It is recognized as a causative agent of anthracnose, a severe disease that affects various agricultural crops. Identifying this pathogen is crucial for modern plant pathology due to its aggressive colonization patterns on host tissues.

The fungus primarily impacts horticultural crops, with a notable prevalence in strawberries and various vegetables. It is known to infect leaves, stems, flowers, and fruits, often causing pre-harvest and post-harvest losses. The pathogen is highly adaptable and can survive on alternative hosts or in plant debris between growing seasons.

Symptoms typically present as sunken necrotic lesions that are dark brown or black in color. As the infection progresses, these lesions develop acervuli, which are tiny cushions producing masses of fungal spores. In severe cases, the infected parts become brittle, leading to fruit shriveling, wilting of the plant, and premature death of the foliage.

The development and dissemination of the disease are heavily influenced by environmental conditions. High humidity, constant leaf wetness, and moderate to warm temperatures facilitate spore germination and infection. Rain splash, irrigation water, and contaminated farm equipment act as the primary vectors for the pathogen to spread across crop fields.

Effective management of Colletotrichum changpingense requires an integrated approach.

• Use certified pathogen-free planting stock.
• Implement strict crop rotation and field sanitation.
• Apply fungicides preventively during critical stages of plant development.
• Monitor fields regularly to detect early infection symptoms.
