does the yates hose on weed and feed for most lawns (the non buffalo one) work against spurge weeds?

The product is registered for bindii, Capeweed, clovers, cudweed, Dandelion, docks, lamb's tongue, thistles and wireweed. Unfortunately spurge weed is not registered under the product label. To control spurge weed, you may try spot spray with Yates Zero Rapid 1-Hour Action Weedkiller which is a contact herbicide. Take care when applying as it will kill any plants it contacts.
