(尤用于战时的)脱叶剂 A defoliant is a chemical used on trees and plants to make all their leaves fall off. Defoliants are especially used in war to remove protection from an enemy.
The USFK says that during the late seventies barrels of other defoliants were buried on base, but were dug up within a few years and removed. 驻韩美军说,1970年代有其他脱叶剂埋在营地内,但在几年内就挖出并移走了。
