Fall Herbicide Crop ApplicationA fall herbicide application is some of the smartest money you'll spend on weed control all year.

Once the crop canopy is removed, winter annuals and biennials soak up moisture and the last rays of sun before winter. In that window before freezing, some winter annuals are able to produce thousands of seeds. If you let the plants go to seed you'll be fighting those weeds for years to come.

Perennial weeds use that post-harvest period to move nutrients into their root systems. Use this natural flow to your advantage by using a burnoff herbicide with systemic control.  This will help to greatly reduce weed biomass which will result in the conservation of soil moisture and nutrients.

Spray extended weed control herbicides late-fall for better spring control. A soil-applied extended weed control herbicide application in the late-fall starts working in the spring after the snow melts and/or spring rain arrives. This creates a barrier that stops spring weeds from emerging.

Learn about our fall herbicides for post-harvest burnoff and extended weed control to get a head start on spring.
