Which type of pathogen is Alternaria dauci?

• A. Fungus
• B. Bacteria
• C. Nematode
• D. Virus

Answer: (A)

Alternaria dauci is classified as a fungus, specifically a plant pathogenic fungus that primarily affects carrots and other crops within the Apiaceae family. This pathogen is known for causing diseases such as alternaria leaf blight, which can lead to significant yield losses in affected crops. Fungi like Alternaria dauci are characterized by their ability to produce spores, which allow them to spread and colonize host plants. They often thrive in conditions of high humidity and can remain dormant in plant debris or soil, waiting for suitable environmental conditions to infect new hosts. Understanding that Alternaria dauci is a fungus is crucial for implementing appropriate management strategies, such as crop rotation, resistant varieties, and fungicide applications, to control its impact on agricultural production.
