IPA: /ˌæɡrɪˈkɛmɪkəl/
KK: /ˌæɡrɪˈkɛmɪkəl/
A substance used in agriculture to enhance the growth of plants or to control pests and diseases.
Farmers often rely on agrichemicals to enhance crop yields and protect against pests.
Agrichemical is formed from "agri-" (from Latin "ager", meaning field or land) and "chemical" (from Greek "khemia", meaning the art of transmuting metals). The word refers to chemicals used in agriculture, particularly in farming and crop production.
Think of 'field' ('agri-') where 'chemicals' are used to help plants grow — that's what agrichemical means.
