Johnsongrass (Sorghum halepense) is a rapidly growing warm-season perennial weed found in cultivated and no-till croplands, perennial field crops, hay fields, roadsides and other wasteland areas. Large johnsongrass populations can be very competitive with soybeans. Yield reduction can happen is a little as three weeks in dry conditions and eight weeks when soil has abundant moisture.
