Which term refers to the progression of a plant disease from initial infection to the end of the disease cycle?

• A. Disease
• B. Disease Cycle
• C. Defoliation
• D. Foliar

Answer: (B)

The progression of a plant disease from the initial infection all the way through to the end of the disease cycle is called the disease cycle. This term covers the entire sequence the pathogen follows: how it begins infection, grows and reproduces, spreads to new hosts, and then starts the next round of infection. It’s more than just the illness itself; it’s the full process that enables the disease to persist and renew itself each season. To contrast briefly: a disease is the harmful condition caused by the pathogen, defoliation is a symptom or outcome (loss of leaves), and foliar refers to the leaves. So the disease cycle specifically describes the full sequence that sustains and propagates the disease. In practice, understanding the cycle helps in timing control measures to interrupt steps like inoculum production or spread.
