Using real round-up (ultra weathermax) at such rates is not only silly from an economical standpoint, but also defeats the effectiveness of roundup's ability to "kill the root". If much more than a quart of real roundup is used (22 oz/acre rec. rate) it becomes a burndown. Fake roundup can be used at rates near what you described so long as plants are not growing well. When plants are growing quickly they are easily killed and are easily burned down without killing the root if too much roundup is applied.
A much lower rate is needed in warm weather when plants have plenty of soil moisture. During a drought or cool weather the rate needs to be increased a bit to achieve a kill.
1.5 times the rate of glyphosphste will be plenty. It is more vital to apply the chemical with adequate water. 10 gallons per acre just won't cut the mustard unless weeds are small and sparse. 12 gallons is better than 10 but 15 is prime. I apply more like 18 gallons for late applications on tough weeds. I use 16 or more for any pre-emergent residuals. It makes all the difference! If its worth doing then its worth doing well!

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
