Stalk Borer Scouting
![Nebraska map showing accumulated GDDs](documents/Stalk%20borer%20map.jpg)
Degree day accumulations indicate that scouting should begin for stalk borer larvae across most of the corn growing areas of Nebraska this week.
Begin scouting corn when 1,300-1400 DD have accumulated. This corresponds with the beginning of larvae moving out of grassy hosts. Determine the need for treatment when 1,400-1,700 DD have accumulated. For more information on scouting and treatment of common stalk borer in corn, see the May 30 CropWatch article.
