IMI (Clearfield) vs conventional seeds for Wildlife/Hunting Plots: Key Takeaways

• If you’re managing a field for wildlife/hunting (e.g., doves, quail, turkeys, deer), the weed control advantage of IMI (Clearfield) sunflowers is very meaningful. Clean stands mean more visible seed heads, easier access for game, and less competition.

• The data show that IMI hybrids are comparable in yield to conventional varieties in trials.  In the presence of weed competition they greatly outyield conventional varieties.   That means choosing the IMI varieties provides consistency in your wildlife plots

• Cost vs benefit: Although IMI seed & required herbicides cost more, the management savings (less replanting, less mechanical weed control, cleaner hunting field) make the investment worth it—especially on plots where weed pressure is high.

• For hunting aesthetics and functionality: clean rows, ample seed heads, and mature seed at the right time matter. IMI sunflowers give you a better chance to deliver that because you can actively control weeds after emergence.
