Weed Control in Winter Wheat

It is that time of year again: time to give special attention to the developing weed problems in winter wheat.  Your fieldman will be conjuring up a weed control program for your winter wheat taking into account the two major areas of concern: grass and broadleaf weed control.  The good news is that there are many options so a program can be tailored for specific weed situations.
  • Grass control herbicides:  Hoelon, Osprey, Powerflex, Maverick, Axial, Everest, Axial TBC.
The main feature of all these herbicides is their control of Annual Ryegrass and Wild Oats.  Each chemical has its strengths and weaknesses in regards to soil residual, Annual Bluegrass and Brome control.  Some of the grass herbicides also have some broadleaf activity and some may be mixed with broadleaf herbicides.
  • Broadleaf Control Herbicides: MCPA, Banvel, Widematch, Aim, Harmony, Hat Trick, Express, Finesse, and Huskie.
Hat Trick is a new herbicide that contains three active ingredients that results very broad spectrum weed control.  Prickly Lettuce is a weed that is becoming more common and can be a problem in winter wheat even causing issues at harvest.  Bedstraw is also a troublesome weed that shows up in wheat.

Your weed control program needs to be developed based on the weed spectrum,and  the stage of growth of both the crop and the weeds.  Your CPS fieldman will be working with you to figure out the best program for your farm.
