The Botanical Society of America announced Tuesday that it has voted to ban flowering plants grown for animal use from the NFL.
The vote was the result of a long-running dispute over the league’s botanical use policy.
The Botanic Society said the ban will take effect Jan. 1, 2019.
The announcement came hours after a meeting of the botanical community in Boston.
The NFL’s Botanical Council, the botanic society’s governing body, voted unanimously to ban plants that could be used for breeding, research, or any other purpose that could endanger players or other team members.
The botanical society said that it will not allow any flowering plants to be grown for any purpose, including research.
Botanical societies, the largest professional baseball league in the United States, have long been at odds with the NFL over its botanical usage policy.
Last month, the league decided to end its use of the common weed-killer Dieldra, which is often used in fields and gardens.
The league’s use of Dieldral is currently restricted to the use of its turf field, a practice that some teams have protested.
