2,4-D alone will not control clover completely in one application, and will not help much with ground ivy.
For good clover control, you need a product like Confront (triclopyr + clopyralid). Confront at 1/3 recommended rate wipes out clover.
Best control on ground ivy is a combo of 2,4-D (or some other phenoxies) and triclopyr, preferably in ester formulation.
Lesco's Momentum = 2,4-D + triclopyr + clopyralid in an amine formulation.
Riverdale's Cool Power = MCPA + triclopyr + dicamba in an ester formulation. This product will quickly clean out ground ivy, and also does a good job on clover.
