The 1st symptom of Leaf curl disease of cotton infection appear within:
Correct answer: B. 2 - 3 weeks
- A. 1 - 2 weeks
- B. 2 - 3 weeks
- C. 3 - 4 weeks
- D. 4 - 5 weeks
Explanation
The correct answer is 2 - 3 weeks. Leaf curl disease symptoms in cotton typically become visible within this timeframe due to the pathogen's incubation period. Options 1 - 2 weeks and 3 - 4 weeks are incorrect because the symptoms generally do not manifest that quickly or take that long to appear. Option 4 - 5 weeks is also too late for the initial appearance of symptoms. Recognizing the typical progression of plant diseases can help determine the correct answer.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
