Relating to treatment or prevention of chlorosis (a plant disease marked by yellowing leaves due to lack of chlorophyll or iron).
Anti- + chlorotic (relating to chlorosis). Chlorosis comes from Greek 'chloros' (green) + -osis (condition). The term emerged in 19th-century botany and agriculture to describe remedies for this plant disease.
Farmers in the 1800s discovered that adding iron to soil prevented chlorosis—'antichlorotic' measures literally made crops greener, increasing food production and solving nutritional problems.
