Workers in a plant nursery check every plant for signs of disease each day. Why does checking daily reduce the total number of plants infected?
Plants that are checked every day recover from a disease more quickly
A pathogen reproduces more slowly inside a plant that is inspected
Infected plants can be removed before the pathogen spreads further
Pests leave a plant as soon as the first signs of disease appear on it
