Foliage death beginning at the tips of the youngest growth is commonly called which symptom?

• A. Stunting
• B. Blight
• C. Canker
• D. Die Back

Answer: (D)

This item is testing your recognition of dieback, a pattern where plant tissue dies back from the ends of shoots toward the base. Foliage dying starting at the tips of the youngest growth is classic dieback because the newest, actively growing tissues are the first to be damaged by stress or disease. Young growth is softer, less lignified, and more dependent on a steady water supply, so it succumbs first to factors like drought, cold injury, nutrient imbalance, or certain pathogens. When dieback occurs, you’ll see tipburn and withering progressing downward along the shoots as the healthy wood is gradually affected. In contrast, stunting refers to overall reduced growth, not the terminal death of new growth; blight involves rapid collapse of leaves or stems over a short period; and canker is a localized sunken area of dead tissue on stems. These patterns don’t describe the progressive dieback starting at the tips of the youngest growth. To manage dieback, address underlying stressors (consistent watering, proper drainage, balanced nutrition), prune away dead tissue to encourage healthy regrowth, and inspect for pests or pathogens that may be contributing.
