I am looking for a cheep vegetation killer. I have about 6 acres of over grown field that i just brush hogged last fall. Now i need to get ride of the new growth. I would like to plant buckwheat or wheat in the same field later this summer or fall. Is there any vetetation killer that i could obtain to do the job. Would the local fruit growers co- op sell me the more potent stuff??? I do understand i could use some round up, but is it quit exspensive. Any thoughts or suggestions.

Thanks
