Why couldn't you have used muster? Everyone used to before herbicide tolerant varieties.SW Wizard, and AC Foremost, are still available and they are OP, you can save the seed but cannot sell it as seed, just food. i planted both together last year for hybrid vigor and sprayed it with centurion. You have to have very clean fields to begin with because there is no control for broad leafs, my yields suck since i am still trying to get my abused land to produce average yields.
If you have a really clean field and have good nutrients i could see 30-34 bu/ac. Centurion at the time was $6 per ac to spray, seed was $2.50 lbs. the pods were crazy big in the low black soil areas. But what a mess for weeds next year.
