Regarding the PG, I do not think it provides proper coverage. A z-spray or a T3000 would be much better. When we see black medic, our T-Men set the cruise control & drive around while using the spray wand (eliminating the need for lugging around a spot sprayer). my 2 cents
i think the purple leaf plant is creeping oxalis
black medic is similar , but tear drop shaped and smaller leaves
t-zone has worked well on black medic for me (only tried it a couple times so far)
trimec is hit or miss on it for me
