Early rapid wheat growth may alter your weed management
Unseasonably warm temperatures experienced earlier this month have increased the growth Michigan’s winter wheat crop. Because of these temperatures we are seeing a wide range of wheat growth stages across Michigan. In fact, several wheat fields have reached or are approaching jointing (Feeke’s stage 6) which needs to be considered when choosing herbicides for weed control. Achieving good herbicide coverage may also be tougher because of early rapid wheat growth. While some of Michigan’s wheat crop has already been sprayed for weed control, here are some considerations for fields that have not yet been treated.

New 2,4-D formulation recommendations for wheat
Three years of research at MSU have shown no differences in winter wheat tolerance between 1 pt/A of 2,4-D amine and 2,4-D ester when applied to wheat at Feeke’s stages 4 to 5 (prior to jointing).

Nitrogen as a spray carrier can affect winter wheat
Over the last three years research has been conducted to answer the following questions:
- What effect will applying my herbicide with 28% UAN (nitrogen) as a spray carrier have on weed control and wheat tolerance?
- Can I reduce this risk by applkying my herbicide with a 50:50 mixture of 28% UAN and water as the spray carrier?
- Will the timing of these herbicide-nitrogen carrier applications influence crop tolerance?

Time is ticking down for herbicide applications in winter wheat
There are several herbicide options available for weed control in winter wheat. However, weed control spectrums and the maximum stages of winter wheat growth when these herbicides can be applied can be very different.

Watch winter wheat growth prior to applying herbicides
Knowing what stage your wheat is at is critical when it comes to making decisions on what herbicide to use for weed control.
