I've had pretty good luck with Image mixed in with Bonide's Turbo Sticker in turf.

The label for round up pro below, says it can control Horseweed. There are many different round up products. Which one are you using?

Annual Weeds
Use 1 quart per acre if weeds are less than 6 inches in height or runner length and 1.5 quarts
to 4 quarts per acre if weeds are over 6 inches in height or runner length or when weeds
are growing under stressed conditions. Use the higher rate for tough-to-control species
regardless of the weed size at application. Treat tough-to-control weeds early when they
are relatively small. This product may be tank-mixed provided that the specific tank-mix
product is registered for use on the target site. Refer to these product labels for approved
sites and application rates.
For spray-to-wet applications, apply a 1/2 percent solution of this product to weeds less
than 6 inches in height or runner length. Apply prior to seedhead formation in grass or bud
formation in broadleaf weeds. For annual weeds over 6 inches tall, or for smaller weeds
growing under stressed conditions, use a 1 to 2 percent solution. Use the higher rate for
tough-to-control species or for weeds over 24 inches tall.

It is probably a glyphosate resistant variety, 1st noticed in Tenn in 2001. http://weedscience.org/summary/species.aspx?WeedID=61

When i spray areas such as rip wrap, fence lines, and gravel lots. I use ranger pro and add some msma or speedzone southern to it. It makes a pretty hot mix, will kill anything i spray with it. I dont have the patience to fool around with having to come back and spray it again next week. With the temps we have been having weeds are visibly dying over night, and crispy brown the next week. Not the cheapest method, but extremely effective. The speedzone leaves a pretty good residual as well.

i have some speedzone. in my experience it isn't all that strong. i sprayed my parent's yard with it and it killed alot of the weeds but nowhere near all of them. i thought it was a waste of money to be honest. we put down a pre emergent this year and not a single weed in the whole yard.

I use Speedzone Southern. I love it for blanket broad leaf applications, I believe it's the Dicamba Acid that makes it work pretty well. It will kill all broad leaf weeds, even wild violets and some oxalis. I just add it to the ranger pro at about 1.5oz per a gallon rate. Works great.
