CORN
Stalk
Borers on the Move
According
to Growing Degree Day accumulations, base 41, stalk borers are starting to move from
grassy areas into nearby corn fields along and south of Highway 34, and areas north of
Highway 34 will be experiencing this in the not-to-distant future. I have noted dead grass heads, as shown in the
picture below.
Information
on scouting and management can be found at the ICM News article at https://www.extension.iastate.edu/CropNews/2014/0530hodgsonsisson.htm.
Local
Growing Degree Day accumulations are shown at https://www.extension.iastate.edu/Pages/eccrops/stalkborer.html.
You
can get an early heads up of the size of potential movement of stalk borers
into corn by examining the grass for dead heads; the vast majority of dead heads will have
been killed by stalk borers who are outgrowing the grass plant and moving into nearby
corn. The more dead heads you find, the more
stalk borers may be poised to move into corn.
