Minnesota Extension IPM Program |

Welcome to the Minnesota Extension IPM Program!

The mission of the Minnesota Extension IPM Program is to foster the development and adoption of IPM to generate economic, environmental and human health benefits. We work in partnership with stakeholders from agricultural, urban and rural settings to identify and address relevant priorities for research, education and outreach.

Monitoring Corn Earworm

Corn Earworm moths are monitored throughout our growing season using a Harstack trap and pheromone lure. From July through September traps are checked daily to detect an uptick in the population of migrating moths. This information is used in multiple ways, one of which is to advise growers on when peak flight activity, therefore peak egg lay, will occur.
