5 Benefits of Fall Weed Control

Taking action against weeds in the fall can pay big dividends in the spring. That’s because controlling actively growing fall weeds can eliminate the need for or increase the effectiveness of any spring burndown herbicide program.  

Although Sonic® is widely used as a spring preemergence herbicide, it also offers several benefits when used in fall weed control applications. When recommending fall weed control to your customers, consider these five benefits of using Sonic herbicide

  1. Allows for spraying on actively germinating weeds when control is most effective 
  2. Spreads out workload, giving farmers greater flexibility in the spring 
  3. Decreases weed competition to maximize the yield potential of emerging soybeans 
  4. Optimizes timing of spring applications to be made on smaller, more-uniform-sized weeds 
  5. Is easy to handle and mixes well with other herbicides for broad-spectrum control 

A general fall application recommendation is 4 to 6 ounces of Sonic herbicide plus 1 to 2 pints of 2,4-D plus 1 percent crop oil concentrate, which takes care of tough weeds like marestail, waterhemp, kochia, Palmer amaranth, chickweed and dandelions. To control emerged grasses add 1 to 2 pints of Durango® DMA® herbicide. Sonic is easy to handle and mixes well with other herbicides for broad-spectrum control. 

For best results, it’s important to apply when the air temperatures are still warm, when weeds are actively growing and when good spray coverage can be achieved.  

Durango® DMA® and Sonic® are not registered for sale or use in all states. Contact your state pesticide regulatory agency to determine if a product is registered for sale or use in your state. Always read and follow label directions.
