We have 120 acres of Bermuda Grass with about 35 Cows and 35 Calves Grazing it. We going to apply some fertilizer on it. We also want to have it sprayed for weeds. Our Co-op just wants to use Graze on Next. The Graze on Next would cost about $17.50 an acre applied. Is there any other herbicides you could use that would not be as Expensive?
