Many of you use herbicides to kill grass and weeds before creating your plots. Roundup seems to be the standard when it comes to weed control. I had read a while ago of a "generic" brand that had the same ingredients as Roundup, but was considerably cheaper. Do any of you use generic brands with good results? What is the name of the product?

Also, I was looking at the Roundup which you mix several ounces of it with water and apply instead of the premixed stuff. Is there any difference between the two as far as strength or results?

Thanks again for the info!
