Systemic fungicides movement is typically associated with protecting which plant parts?

• A. Upper leaves and tops
• B. Roots
• C. Lower stems
• D. Seeds

Answer: (A)

Systemic fungicides are absorbed by the plant and moved through its vascular system, typically upward through the xylem as water moves from roots to shoots. This upward movement carries the active chemical to new, actively growing tissues, so it most consistently protects the upper parts of the plant where new leaves and shoots form—i.e., the upper leaves and the tops. While these products can reach other tissues as well, their notable protection is with the newest growth at the top.
