The lack of which element causes the 'dieback' disease?
Think it through first, then pick an option.
- a calcium
- b sulphur
- c magnesium
- d potassium
Answer and explanation
Correct answer: b sulphur
Lack of sulphur makes tissue die one after another starting from the tips of roots, stem and leaves, which is called dieback.
Why the other options are wrong
- a calcium: “calcium” does not fit here. Lack of sulphur makes tissue die one after another starting from the tips of roots, stem and leaves, which is called dieback.
- c magnesium: “magnesium” does not fit here. Lack of sulphur makes tissue die one after another starting from the tips of roots, stem and leaves, which is called dieback.
- d potassium: “potassium” does not fit here. Lack of sulphur makes tissue die one after another starting from the tips of roots, stem and leaves, which is called dieback.
