Root rot is a plant disease caused by various types of fungi that infect the roots of plants, leading to their decay and ultimately death. This disease is particularly common in crops such as soybeans, potatoes, and tomatoes, as well as in ornamental plants like rhododendrons and azaleas. Symptoms of root rot include wilting, yellowing of leaves, stunted growth, and ultimately death of the plant. The fungi responsible for root rot thrive in wet and poorly-drained soil, making proper irrigation and drainage essential for prevention. Control methods for root rot include using fungicides, improving soil drainage, selecting resistant plant varieties, and practicing proper crop rotation. Research in this area focuses on understanding the mechanisms of root rot infection, developing new control strategies, and finding ways to mitigate the economic impact of this disease on agricultural production.
