Let me be honest. I live in Houston but this is the only TX site and
besides my cousin lives in Austin. Sorry to see the Horns lose to LSU.
Anyways we have some summer squash growing currently in an immature state as
the flowers haven't appeared. Anyways, I recently identified some small
(appx 1/8" dia) light brown spots on the leaves. The underside is
definitely eaten out where the spots are. I couldn't identify any bugs on
the plant, but I went ahead and applied GardenSafe Insecticide on top and on
bottom. A few days later the spots seemed to hav darkened. I can't say
that they've got worse (but I can't say that they haven't).

Any ideas?
