[Dr. Bob Scott] In addition to ryegrass there are a number of broadleaf weeds that infest Arkansas wheat. One that I’m primarily concerned about is horseweed. The reason I’m concerned about it is not so much for the wheat production, [Picture of a field with horseweed infestation] it takes a tremendous amount of horseweed to actually impact wheat production in Arkansas. [Picture of wheat plots] However, most of our horseweed in the state is resistant to glyphosate [Map of the state of Arkansas showing counties where herbicide resistant horseweed is found]  and a lot of our wheat acres are followed by round-up ready soybeans. So if you intend to grow round-up ready soybeans behind wheat in a double crop, [Dr. Bob Scott] it becomes very important to control the horseweed in the wheat so that it doesn't interfere with soybeans.

[Picture of emerging wheat] One of the best options for horseweed control can be applied once the wheat is finished tillering but prior to joint elongation. [Drawing showing a mixing tank with 1 1/2 pints of 2,4-D and 1/2 ounce of Harmony-Extra being poured into the tank.] This application is a pint and a half of 2, 4-D, tank mixed with a half ounce of Harmony-Extra. And we have observed over ninety percent control of horseweed with this program.
