“The Grinder” takes on tough soils, tough conditions, and even tough diseases and out-yields the rest. Strong Goss’s Wilt and northern corn leaf blight tolerance. Versatile hybrid that fits across all acres.


Average test weight.


This is a “place anywhere” kind of hybrid that does respond well to increased management including precision fertility, fungicide applications, increased planting populations, and even narrow row spacings. Works well even in continuous corn situations with in-furrow insecticide.

I have been trying a couple of bags for the last couple of years. I will definitely do more in the years to come. Hefty 3322 pops out of the ground much better than the competition.
