Most of the 2015 wheat crop faired considerably well over the winter. Over the next couple of weeks, many of these acres will be treated with herbicides for weed control. While there are several herbicide options available for use in wheat, there are many factors that growers should consider prior to deciding when to spray and what products to use.

The colder than normal spring and recent wet weather has made it difficult to spray winter wheat this year for weeds. While we normally would have all of our wheat herbicides applied by now, there are still several fields that have not been sprayed. However, winter wheat has continued to grow...

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.

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).

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?

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.

Knowing what stage your wheat is at is critical when it comes to making decisions on what herbicide to use for weed control.

Of all the crops grown in Michigan, winter wheat has typically been the crop that has not been intensively managed. However with higher wheat prices, growers are looking at more intensive management to maximize yield.

Several effective options are available for management of annual weeds in wheat stubble. However, these practices must be implemented before seed production to avoid significant additions of seeds to the weed seed bank.

Over the next month, many of Michigan’s winter wheat acres will be treated with herbicides for weed control. While there are several herbicide options available for use in wheat, there are many factors that growers should consider prior to deciding when to spray and what products to use.
