QUESTION - my lawn is suffering from this brown patch fungus - that along with the high heat/humidity in Atlanta, Ga (zip=30314) about 80-90% of my fescue lawn is tan/straw colored and the grass looks DEAD... it was nice & plush - deep green about 4" tall at its best but now im pretty sure its all dead or dying!! I used one application of Spectracide Immunox Lawn Disease Control Granules so far - of course I didn't see any difference - they say it takes 2-3 applications but how do I know its working? what I am going to see if this stuff starts working? is there anyway to get the straw colored grass back to green or is it officially RIP and I just have to start over...? or should I just scalp the whole lawn - try to baby the remaining little bit of green grass and start over in the fall and reseed?
