As larvae, they hatch in the soil when corn is at its most vulnerable and feed on the roots—eating away at your yields and threatening harvestability. As adults, they feed on silks - interfering with pollination and undermining the efforts and resources you’ve devoted to your crop.
Corn rootworm populations are noted to have increased in corn-on-corn rotations and some areas of first-year corn—and possibly coming to a field near you. Understanding how to manage this pest is absolutely critical to a successful yield and the very future of growing corn.
Read on to learn more about the corn rootworm, how each stage of this pest’s life cycle presents unique threats to your corn plants, how to detect and measure corn rootworm damage and why corn rootworm challenges to standard management practices (including crop rotation) have become a reality.
This module, which focuses on the characteristics of corn rootworm and the effects of corn rootworm damage, is the first in a two-part series devoted to corn rootworm management. The second module, Corn Rootworm Management Recommendations from Syngenta
, which details dynamic corn rootworm management recommendations offered by Syngenta, is also available on the FarmAssist website.
