Effective Buttonweed control?

[vegomatic40]

Due to our prolonged drought, I haven't seen much buttonweed this season but would like opinions on control products and/or methods. I've yet to find a product that I could offers better than 50% control. Any ideas?

virginia buttonweed?

if so, two apps, 6 weeks apart(you can hit it again on the next round)of either manor or blade(metsulfuron) will do the trick!

nasty stuff if a lawn is over run by it

Thanks for the reply but I guess I should have said "in Turf-Type Fescue" as it isn't labled.

Speedzone southern works well. Takes two apps.
