Japanese Beetles Wreaking Havoc on Midwest Soybeans

July 24, 2017
This agronomic image shows a Japanese beetle.

After hearing late June reports of Japanese beetles beginning to show up in soybean fields of eastern Nebraska and Illinois, we’re now seeing their presence in significant numbers.

Donald Lewis, Entomology Professor at Iowa State University, says 2017 will be remembered as one of the worst years in recent memory for Japanese beetles in Iowa.

When scouting for Japanese beetles, University of Illinois says to look for:

  • Metallic, green bodies
  • Half inch long
  • Bronze-colored wing covers
  • Six small tufts of white hairs along the side of their bodies

Should Japanese beetles reach the local thresholds in soybean fields for your state, Syngenta recommends treating them with Endigo® ZC insecticide, a proven solution to prevent soybean damage from a wide range of pests for higher yield potential.
