Abstract

One of the most difficult tasks associated with the management of weedy grasses is accurately identifying the species of an immature plant. Since many grasses look similar when very young, identification to species is key to correctly implementing a weed management program, especially one using herbicides. This guide aids in identifying and distinguishing johnsongrass and other grass species that appear similar when immature, using distribution maps of United States counties where each species has been reported, photographs, and diagnostic characteristics using distribution maps of United States counties where each species has been reported, photographs, and diagnostic characteristics for each species.
