Which term refers to a disease that can invade vascular tissue and spread throughout all parts of a plant?

• A. Systemic Disease
• B. Localized Disease
• C. Fungal Disease
• D. Viral Disease

Answer: (A)

Systemic disease describes infections that move through the plant’s vascular system (xylem and phloem) and can spread from one tissue to another, affecting roots, stems, and leaves. When a disease is systemic, symptoms show up in many parts of the plant because the pathogen has traveled internally, not just at a single spot. In turf management, this means the issue isn’t limited to where the plant was first infected; control often needs systemic approaches or resistant varieties since the pathogen can reach all parts of the plant. The other terms describe either where the disease is located (localized) or the type of pathogen (fungal or viral), but they don’t specifically capture the plant-wide spread through the vascular system like systemic disease does.
