An effective cereal grain herbicide plan should start with a good burndown to give emerging grains the best opportunity to take up water and essential nutrients instead of competing for them against encroaching broadleaf weeds and grasses.
After evaluating the success of the burndown (or tillage) and its impact on early season weed control, you most likely will determine a preemergence herbicide application will be needed to control tough weeds like herbicide-resistant kochia, waterhemp, marestail (horseweed), and other broadleaf weeds or grasses found.
Look at the herbicide rates that were used on the weeds last year, remembering which modes of action (groups) were used. Continue to strengthen your stewardship of effective herbicides by rotating modes of action at every opportunity.
Once the crop is up, be vigilant. Protect the investment you have made with a postemergence application to extend your commitment to start clean and stay clean. Scout often and look for escapes to prevent a weed flush weeks later.
Take advantage of new products
It is not often farmers get a new herbicide product that can make an immediate and positive impact on weed control across cereal acres. But this year, cereal farmers in the PNW and northern Plains are readily embracing Tolvera® herbicide and the active ingredient new to the cereals market that it brings — tolpyralate (a Group 27).
Field-tested and proven to provide effective broadleaf and grass weed control in spring and winter wheat, durum and barley, Tolvera herbicide holsters two modes of action. In addition to tolpyralate, Tolvera herbicide includes bromoxynil, a Group 6 photosynthesis ll inhibitor. Check out this fact sheet about Tolvera herbicide for additional information.
With a nine-month plant-back to most major crops, Tolvera herbicide gives growers the freedom to rotate to the crop that best improves their profitability potential. It also provides tank-mix flexibility to address local weed spectrum needs.
Never underestimate the benefits of a program approach to weed management. A program approach will support your Integrated Pest Management efforts by allowing for more strategic and targeted use of herbicides to minimize impact on the environment.
