Still on the path of the Black Cutworm, some 17 Buena Vista and Sac 4-H'ers and their parents investigated early corn damage due to Black Cutworm at the June 4-H Crop Scout Field Class held at Newell Farmer's Cooperative Test Plot south of Storm Lake.
ISU Extension Crops Specialist, Paul Kassel, lead the scouting party to low lying areas of the field where field corn emergence was at the 5-true leaf stage. The group scouted three identified areas across the field and were asked to look for black cutworm evidence recognized by a wilted central leaf.
Kassel also led the team in checking soybean plant populations measuring out three feet of the row, counting the plants and figuring the stand count. ISU Extension Asian Soybean Rust First Detector, Mike Sandhoff, representing Citizens First National Bank of Storm Lake, assisted the team in both general scouting techniques and the use of GPS technology in the crop scout profession.
Each 4-H Crop Scout received an ISU Extension GPS Receiver to use for their scouting work over the summer. They will be identifying and monitoring local fields as a part of their 4-H project experiences.
The 4-H Crop Scouts have spent the last three months monitoring their individual pheromone traps to capture Black Cutworm moths migrating from Mexico to Iowa. The 4-H'ers reported their individual findings on the Iowa State University Department of Entomology Black Cutworm Monitoring Network's web site.
4-H Crop Scout Members include: Buena Vista County: Austin Ehlers, Nicholas Klahs and Joe Sandhoff, Storm Lake; Mitch and Nick Sievers, Albert City. Sac County: Ben Degner, Fonda; Derek Huser, Sac City; Tyler Pickhinke, Early; Craig Blass, Sac City.
