Gordons Ornamec 170 Grass Herbicide should be mixed at approx. 10 oz per gallon of water to treat grassy weeds in Vinca. Ornamec will not kill existing clover. For clover in ornamental ground covers like vinca major/minor, you can carefully spot treat using a non-selective herbicide such as Killzall Herbicide.
