Vascular wilt diseases are plant diseases caused by pathogens that infect the vascular system, primarily affecting the xylem. These diseases are often caused by fungi, bacteria, or nematodes, leading to symptoms such as wilting, yellowing leaves, and stunted growth. Common examples include Fusarium wilt and Verticillium wilt, which can affect a wide range of plants. The pathogens block water and nutrient transport, causing the plant to become dehydrated. Vascular wilt diseases can spread through contaminated soil, water, or plant material, making management challenging. Early detection and proper cultural practices are essential for controlling these diseases and minimizing their impact on crops.
