fungi（真菌）+ cide（杀，像pesticide杀虫剂）→ 杀真菌剂。
语域：mixed 常见场景：农业、园艺、化工/实验室、产品说明 该词是专业术语，通常多用于农业、园艺、化工等专业或半专业场景，也常见于产品说明书和新闻报道；正式程度中等，日常随意口语中使用较少。
这些词都以 -cide 结尾，末尾读音均为 /saɪd/，且重音都落在第一个音节；但各词第一个音节的元音不同（fungicide 是 /ʌ/，pesticide 是 /ɛ/，herbicide、spermicide 是 /ɜː/，homicide 是 /ɑː/，suicide 是 /uː/，genocide 是 /ɛ/），所以没有整词押韵。注意 fungicide 中的 -ge- 读 /dʒ/，不要读成 /ɡ/；形近词 fungi 读 /ˈfʌŋɡiː/ 或 /ˈfʌndʒaɪ/，与 fungicide 读音不同。
