2-4-D kills most weeds in the yard but be careful when using it on St. Augustine. My problem with it is that, since my spraying license lapsed, I can't buy it in bulk (or anything containing 2-4-D) so I have to buy it in quarts. Not really a hardship, just more expensive as I used to use a 2-4-D containing chemical on my pasture as well.
By the way, my yard spraying setup is similar to yours only I use a Fimco 30 gallon tank tow behind,
