Is chemical weed control safe in sunflower fields for dove hunting?

Pre-Application Precautions

Before applying chemical weed control to sunflower fields, dove hunters should ensure they have an integrated pest management (IPM) plan in place. This plan should include scouting, identification of target weeds, and selection of the most effective herbicides. For example, a 1-2 inch application of a non-selective herbicide such as glyphosate can be effective against annual weeds like pigweed and ragweed. However, this may also harm the sunflowers, so timing is crucial.

Application Timing and Technique

Proper timing is essential for safe and effective chemical weed control in sunflower fields. Apply herbicides when the target weeds are actively growing and the sunflowers are 6-8 inches tall. Avoid application during periods of high winds, heavy rain, or direct sunlight, as this can increase drift and reduce effectiveness. Use a low-drift boom sprayer at a height of 12-18 inches above the crop canopy to minimize damage to the sunflowers.

Post-Application Considerations

After applying chemical weed control, dove hunters should wait at least 7-10 days before allowing hunters into the field. This allows time for any drifted herbicides to dissipate and minimizes the risk of exposure to hunters. Regularly inspect the field for any signs of herbicide damage to the sunflowers, and be prepared to reseed or replant any damaged areas as needed.
