Bears a remarkable resemblence to crabgrass, though I hate to do more
than a suggested id of a grassy weed by photo, especially one in vegetative
condition.

If it is crabgrass, the cure is mostly cultural... proper mowing
and fertilization. It's an annual species and there's probably
20 years worth of seed in the soil. Easiest thing to do is just to
get the lawn growing so well that it can outcompete the crabgrass,
which is actually fairly easy to do.

If it's quackgrass, it's another kettle of fish entirely -- that's a rather
nasty rhizomatous perennial. Or you might have still another species.

Your local extension service can id it for you easily, but in any case,
a thicker lawn will make your weed problem much easier to solve.
