Defoliant
Defoliant
Defoliant (/dɪˈfoʊliənt/) is a type of chemical substance that is used to cause the leaves of plants to fall off.
Etymology
The term "defoliant" is derived from the Latin words "de-" meaning "down from" and "folium" meaning "leaf".
Usage
Defoliants are often used in agriculture to facilitate harvesting, as removing the leaves from plants can make it easier to reach the fruit or other parts of the plant that are being harvested. They are also used in warfare to remove foliage that could provide cover for the enemy. One of the most well-known uses of defoliants in warfare was during the Vietnam War, when the U.S. military used a defoliant known as Agent Orange to clear dense jungle vegetation.

Health Effects

Environmental Impact
The use of defoliants can have significant environmental impacts, including loss of biodiversity, soil erosion, and contamination of water sources.
