Foliage death that begins at the tips of the youngest growth is known as which symptom?

• A. Blight
• B. Die Back
• C. Root Knot
• D. Stunting

Answer: (B)

Dieback is the pattern where foliage dies back from the tips of the youngest growth. The tips of new shoots are the most actively growing and often the most sensitive to stress, so they are the first to show damage; the dying tissue then extends backward toward the older growth. This distinguishes it from other issues: blight involves rapid, widespread tissue collapse on leaves or stems, root knot relates to nematode damage on roots, and stunting is an overall reduction in growth rather than death starting at the tips. Recognizing dieback points you toward causes like water stress, cold injury, or root/vascular problems and guides actions such as adjusting irrigation, inspecting roots, and removing dead growth.
