I tested five herbicides against clover. I used hand sprayers. I tried to use the label rate, but the method is approximate. After 48 hours, I found that in my judgment Speedzone was most effective, T-Zone was second, followed by a three-way and then Quicksilver and Drive. I will take another close look tomorrow. Black medic was included in the T-Zone, Quicksilver, and Drive micro plots. How does this compare to your experience?
