Lawn Grass Diseases
Sunday September 16, 2007
Lawn grass diseases are difficult to identify without the aid of pictures. That's just what this site from Cornell University provides. Use this resource to access pictures of common lawn grass diseases: brown patch, dollar spot, fairy rings, leaf spot, pythium, red thread, rust and snow mold.

Lawn has large patches of grass that looks like grub worms only very severe. I have a very large front, back and side yard and it is all over. I was told it was heat stress, but it isn’t. Could be a fungi, or some kind of bug, but has gotten worse over the summer. Where affected it is very spotty and almost looks like it is diying. Help! I’m in TX. on the plains.
Take a sample of the affected turf/soil to your local county extension to get a positive ID on whatever ails your lawn (fungus, bug, whatever). Then follow their recommendations to correct the problem. It may mean spraying, for example, to kill whatever it is (but such a diagnosis can’t really be done well over the Web). When the culprit is killed, re-seed.
while outside I noticed that my lawn looked like someone had sprayed small patches of purple paint on my lawn. After closer inspection I noted that it appeared to be tiny clusters of eggs or granuals of some sort. Do you have any idea what this could be?
Could be a slime mold. While the name sounds ominous, slime molds aren’t generally considered lawn grass diseases, per se, as they pose no serious threat to your grass. You could just rake or mow the slime mold off, if it really bothers you. Slime molds thrive in wet, humid conditions, so you might also try cutting back on watering if the slime mold mars the appearance of your lawn too much (purely an aesthetic consideration) and you’d like to reduce the probability of its reappearing.
