Corn and Sorghum Weeds
Weeds in grain sorghum can reduce yield, harbor insects
and diseases and create problems at harvest. Weeds can be
controlled by tillage or by using herbicides available for
sorghum. Even though sorghum eventually establishes a
dense canopy, it is not particularly competitive with weeds
early in the season because the crop develops slowly.
Controlling grass weeds in sorghum can be problematic
because of the limited effectiveness of herbicides available
for post-emergence applications. So, pre-plant application
of herbicides is recommended for grass control, or the use of
seed safeners that allow the application of more effective postemergence herbicides. Most broadleaf weeds can be readily
controlled in sorghum with tillage or herbicides, or the crop
can out-compete these weeds. One exception is morninglory,
which can grow over the crop creating problems at harvest,
so this weed should not be tolerated.
Grain sorghum (milo) is a warm season, annual grain crop. It is more resistant to salt, drought, and heat stress than most other crops. Nevertheless, highest yields are obtained when stresses are minimized. This Article give some suggestion on planting, fertilizing, irrigation and other aspects of growing.
