Can anyone tell me about this disease? I understand that it is a virus and not a fungus which means the normal organic approach may not work. I'm just not sure if this is what I have or if it's just lack of iron. The lawn has recently started turning yellow is sort of a irregular circle pattern.

I live in the Oak Cliff Texas which has white rock and black soil. I have been organic for many years and have a local Redenta's lawn care service so am sure I'm getting the proper organic maintenance program.

Also, I've recently had a terrible white fly infestation. I've sprayed with the recommended garlic pepper tea and will continue to see if I can't get rid of them. Just not sure what has caused all these problems all of a sudden.

Does your grass look like this?

My guess is you either have a fungus or bugs. Get your lawn service to diagnose and treat it. The treatment for fungus is corn meal. The treatment for most bugs is beneficial nematodes.
