What is one symptom of Bean common mosaic potyvirus?

Bean common mosaic potyvirus is known for causing significant damage to bean plants, and one of the most notable symptoms it induces is stunted growth. This occurs because the virus disrupts various physiological processes within the plant, affecting nutrient uptake and overall development. Affected plants often exhibit reduced height and poor vigor, which can limit their yield potential.

While leaf drop, fruit crinkling, and flower shedding may occur due to other stressors or diseases, stunted growth is a hallmark sign specifically associated with viral infections like Bean common mosaic potyvirus. It highlights the overall impact of the virus on the plant's health and development, making it a critical symptom for identification and management of the disease.
