Do you remember the numbered code of the seed type printed on the bag? There are now 50+ different RR field corn seed available between several brands. $96 a bagwould be one of the cheaper ones.You could have asked for a short growing 85 day RR corn to reach maturity at end of summer.

RR corn could be killed by too heavy a dose of Roundup. How heavy did you spray the Roundup (glyphosate)? If your field is measured, sprayer is measured,application speedand spray width measured .... youthen know how much you are actually spraying per acre. In second gear I spray 20.42 gallons per acre, so I add 2 qts glyphosate to 20 gallons of H2O and sprayaway.
