Clearfield Sunflowers are a hybrid sunflower that allows further chemical control post-seeding. They allow game managers to use both common pre-emergent herbicides, as well as Beyond herbicide following seeding. Clearfield Sunflowers are commonly used as a dove attractant and can be drilled or broadcasted. Plant into a clean, firm seedbed.
Seeding Rate: ≈ 20,000-25,000 seeds/acre
200,000 seeds/bag ≈ 10 acres/bag
