Watch the Worm: Corn Rootworm Trial

When growing corn in back-to-back years, pests like corn rootworm (CRW) can be a common issue for many growers – leading to reduced corn yields and ROI potential.
This summer during a trial at the Slater, IA, Grow More™ Experience site, we are observing hybrids with and without CRW management.
The CRW trial, which has been corn-on-corn for the past 10 years, is inoculated so that agronomists can see pest pressure each year and weigh the different management practices. Syngenta agronomists have seen the following takeaways with the CRW trial:
- Hybrids without CRW traits were likely to experience heavy CRW feeding, which in some cases, led to stalk lodging.
- By comparison, the hybrids that were left untreated reached 2.5 on the 3-point CRW node injury scale from Iowa State University.
To get ahead of CRW damage, Syngenta agronomists recommend using a product like Force Evo® corn insecticide. Force Evo helps deliver superior control of CRW and other early-season insect pests – protecting against economic damage to corn roots.
When used on top of CRW traits in corn hybrids, Force Evo provides an average yield increase of approximately 10 bu/A.
