Labeled rates of corn rootworm insecticides were evaluated across Iowa during the past three years in six locations per year. Five of the fields were conventional-till (chisel plowed in the fall and field cultivated in the spring). The sixth field was no-till. Tests were conducted in various soil types and under various moisture conditions. All products were evaluated in replicated side-by-side tests for their ability to protect corn roots from corn rootworm larval injury.
