Lasiodiplodia is a genus of fungi known for its role as a plant pathogen. It primarily affects various crops and trees, leading to diseases such as fruit rot and stem canker. The fungi thrive in warm, humid environments and can spread through infected plant material or soil. This genus is particularly significant in agriculture, as it can cause substantial economic losses. Effective management strategies include proper sanitation, crop rotation, and the use of resistant plant varieties to minimize the impact of Lasiodiplodia infections on affected plants.
