Please be sure to watch your fields for cutworm activity. We found some eating on this young field corn south of Galesville yesterday morning. They hid just below the surface during the day. Purdue has a nice write-up on cutworm. Click here for more information: https://extension.entm.purdue.edu/fieldcropsipm/insects/corn-cutworms.php
UW has another nice article on cutworm activity this spring: http://ipcm.wisc.edu/blog/2016/05/black-cutworms-in-corn/
Please let us know if you need help looking for this pest in your corn.
