Scouting tips

Scout early and scout often, at least once every five days from mid-July until August.

Focus on the uppermost three or four leaves of the plant, searching for egg masses on the upper surface of the leaves or larvae on the tassels. Bright sunlight can help you spot shadows of egg masses through leaves.

Scout fields in pre-tassel stage first, as late-planted corn is less at-risk early in the season. After the late-tassel stage, WBC moths prefer to seek out dry beans or later planted corn fields.

White band along margin of each wing
Wings have a full-moon and boomerang mark

Eggs laid in masses of 5 to 200 eggs
Typically on the upper surface of corn leaves, close to tassel
Each egg is the size of a pin head
They start pearly white and darken towards the time of hatching
Egg laying can occur any time from mid-June to the end of August

Dark heads with spots along body
As they age, heads lighten and bodies turn tan/pink
Subtle, lengthwise stripes
Dark brown stripes develop behind the head
It is important to target larvae before they move into the silks and ears, where they are less likely to be affected by insecticides.
After hatching, there is a 5-7 day spray window. Spray applications should be timed at egg hatch or to small larvae.
