The Devil's Grass: Quackgrass

Abstract

Quackgrass [Agropyron repens (L.) Beauv. #3 AGRRE] infests farms and gardens throughout the northern United States, southern Canada, almost all of Europe—its native home—and parts of Asia. It grows in Alaska, extends above the Arctic Circle in Norway, and plagues coffee plantations in New Guinea. While quackgrass occurs in every state in the United States, it is rarely a troublesome crop weed in the South.
