Apply today's chemicals to a sorghum crop for grass control and the sorghum will be killed off also. But a solution could be only a few years away if Texas AgriLife Research plots are any indication.

Brent Bean, Ph.D., AgriLife Research and Texas AgriLife Extension Service agronomist, has test plots that demonstrate sorghum hybrids tolerant to herbicides typically associated with grass control. The control is needed not only for annual grass control but also for Johnsongrass, Bean said. Because Johnsongrass is closely related to grain sorghum, herbicides typically used in crops such as cotton and corn cannot be used in sorghum.
