Is it Centipede grass? Centipede has a die back problem. IT starts in a
small spot and spreads out. If this is the grass and the case, keep the dead
grass raked and new crawlers will cover the spot..

I did with the Scott's but frankly can't remember about the Diazinon. I'd
like to think that I followed the directions to make sure it got all
soaked
in. I assumed the problem was below the lawn. What bug(s) is causing this
problem? Thanks, Steve T.

Something eating the roots. Lawn appears to be just laying on top of
soil. I have used Scott's Summer Blend fertilizer and followed up with
Ortho Diazinon a few weeks later with no help. Newer areas continue to
appear. Any ideas would be appreciated. Thank you, Steve T.

Did you water in the diazinon immediately? It only lasts for about
12 hours if it's in the sun, without irrigation.
