....dandelions.

The topic of handy-dandy weedkiller applicators seems to come up at
least as often as dandelions do. I just ran across another nifty
herbicide applicator for people who'd rather not spray: The Dandy-Lion
Killer. It's a spray tank and wetter/roller applicator on wheels. Two
versions - a 3-foot wide one to push, and a larger one (4 foot or 6
foot) to tow behind your lawn tractor. No spray drift.
