It is a major problem in corn, sorghum, and soybean fields in the Central U.S., but is usually less troublesome than johnsongrass in California. Commercial sorghum pollinated by shattercane produces seed that is indistinguishable from commercial sorghum seed. Contaminated commercial seed produces weedy and off-type sorghums that are distinguishable only when the crop matures to the flowering stage. Introduced from Africa. First blade usually parallel to ground.
Midvein whitish at blade base.
Collar narrow, whitish. Sheath round or slightly compressed, pale green to reddish. Ligules resemble those of mature plants. Attached seeds resemble those of johnsongrass , but are mostly 2.5-4 mm wide . Typically tufted, with tillers from the crown.
