BMPs for no-till systems are listed below. Early application places herbicides on the soil when there is less likelihood of large rainfall and runoff events. Alternatively, the second application can be with a nonatrazine alternative. If an initial application controls weeds effectively, a post application may not be necessary. Reduced atrazine rates in no-till may be effective.
Combination products provide wide spectrum weed control with lower atrazine rates.
If needed, spot spraying or postemergence application can control weed escapes. Sprayer Calibration Sprayer calibration is recommended prior to all herbicide applications. Sprayer calibration is essential to assure uniform and accurate herbicide application. Allow ample time to calibrate sprayers prior to planting and spraying. Uniformity among nozzles insures the application rate is even across the total sprayer swath.
