Weed of the Week: Johnsongrass (Sorghum halepense):
Johnsongrass is a warm season perennial grass that is one of the most common and troublesome weeds in agriculture. It is commonly found on roadsides, pastures and hay fields. It grows erect from 3 to 6 feet. Johnsongrass spreads by seeds and rhizomes (underground stems). The seedhead is a large, open panicle often with a purplish tint. Johnsongrass leaves have a large white midrib and a smooth, glossy appearance. Stems are smooth with no hairs.
