Fall Herbicide Application: It’s About More than Weeds 

There’s nothing more challenging when spring planting rolls around than knowing you can’t get in the field. But there’s more than just weeds that may be keeping you from getting that crop in the ground. Uncertain spring weather, soil conditions and field pests can also leave your machines in park.

That’s why fall herbicide application is about more than just managing weeds.

According to Kevin Bradley, associate professor with the University of Missouri Division of Plant Sciences, there are three additional reasons why you should consider fall herbicide application.

  1. Spring Weather Uncertainty.
  2. Impact on Soil Conditions.
  3. Other Pest Interactions.


Fall herbicide application first came about because some growers needed to spread out their spring workloads. And, that just makes sense. For example, Bradley reports the number of suitable field workdays in Missouri, on a 30-year average, is 23.7 for October compared to only 11.2 for March.

It’s no secret that dense mats of winter annual weeds can make spring planting difficult. That’s why removing those winter annuals with fall herbicide applications makes so much sense. Bradley notes winter annual weeds can actually increase soil temperatures and “wick” significant amounts of moisture from the soil in addition to taking up available soil nutrients otherwise intended for developing crops.

Winter annual weeds aren’t just a nuisance at planting time; they also play host to soybean cyst nematode. Bradley cites that in soybeans, removal of winter annual weeds with fall herbicide applications reduced total insect populations tenfold soon after soybean planting compared to areas where winter annual weeds remained until seven days before planting.

As you consider fall herbicide application, Autumn Super™ is a name to remember as it controls both grass and broadleaf weeds. When doing a fall burndown, Autumn Super can help you manage your workload by controlling winter annuals early instead of during the busy spring.

Battling weeds may be a year-round challenge, but getting a jump start on managing them this fall will help you get your tractor in gear sooner when spring planting rolls around.
