RancherSam.....you are making it way too complicated. If you want a strong kill, i.e., you have a lot of broadleaf you are wanting to kill, then mix the 24-D about 2 ounces per gallon of water. If you have a 60 gallon sprayer then you would put about 120 ounces of 2-4-D in your spray rig and then fill it with water and perhaps some common dish soap which works as a sticker agent...cheaper than the stuff they sell just for that use.

Hook up and start spraying.....stop, get off the tractor and walk back to the area you just sprayed....is it fairly wet? does it look like you got good coverage? If so then jump back on the tractor and keep spraying. 2-4-D is cheap....now with some of the other stuff, I would say you might need to calibrate.

Another thing you might do is this.....Fill your tank with just water. Turn the spray rig on while sitting on an area that is plain dirt. That way you can see if your nozzles are at the proper height and are giving you a good overlapping cover. Then you can mix the spray and go to work. I have found that within two hours, if you spray on a good sunny day, you will see how good your kill rate has been. Most broadleaf plants will start showing signs of spray in that period of time. I like to say you can see their heads start hanging down and they look like their sick.

Have fun....nothing more satisfying, well next to plowing, than to spray a broadleaf infested area and see the plants getting sick.....makes you realize their is a God and a hoe is NOT an extension of your arm.
