I worked a summer doing field inspections for a seed corn company where I grew up in SW Minnesota. After the production year of 1993, when we had a cold growing season and a lot of rain, the company no longer raised seed corn. My job was to inspect the seed corn production field early on for evaluating how the "rogueing" crew did for removing "rogue" corn plants, and then later on for de-tasselling. The company had just purchased mechanical de-tasselling machines made by Hagie, the highboy sprayer company. These machines covered 6-30 inch rows per pass. They were powered by 318 Chrysler V-8 engines with dual exhaust..........nice sounding engines back then. They went through with the first machine which had rotary cutting blades, during the early part of tassel emergence. After that, they went through with the next type machine which had rollers resembling the rollers in a ringer type washing machine. By going through first with the cutter style attachment, they hoped to remove the 50 to 60 percent of the tassel itself AND leave a "stump" which could be pulled by the rollers. By leaving that "stump," it was caught easier by the rollers. They typically did 2 trips through with the roller type de-tasseller, and sometimes three trips. After these trips, it was expected to have at least 95 percent of the tassels removed, and leaving the rest to the detasselling crews. I walked through 12 fields a day during the critical tassel stage of these production fields prior to the emergence of tassels until the detasselling was complete and the corn completed pollination. I am not sure about today, but I think the female plants today are "male sterile" and do not need the tassels removed.
