Corn is infested by stalk borer when stalk borer larvae move to find bigger host plants, typically adjacent to grassy edges of emerging corn. The most susceptible stages of infestation are at V1-V5, or about 2-24 inches in plant height.

Mark Honeyman, Research and Demonstration Farms
The latest in field-based research of crop production and management will be on display beginning June 15 at Iowa State University Research and Demonstration Farm field days across Iowa.
Field days consist of tours of research and demonstration plots at the farms. Topics vary for each farm depending on local interest and conditions.
The public is welcome to attend the field days, which take place rain or shine. They are free unless noted.
