Extract

Johnsongrass [Sorghum halepense (L.) Pers. # SORHA], native to the Mediterranean region, is one of the worst weeds ever introduced into the United States. While the precise date of its introduction is unknown, johnsongrass probably was present early in the 19th century. Before 1874, johnsongrass, described under eight botanical names and identified by over 40 common names in the literature, was most commonly called guinea grass and Means grass.
