| Has anyone had experience with necrotic ringspot? I have tried everything. And I've read that it needs to run its course which could take 7 years! |

| Otherwise known as fairy ring or fairy circle. It is any of a small number of fungal diseases. I have always had good luck treating with ordinary corn meal at a rate of 20 pounds per 1,000 square feet over the entire lawn. Do the entire lawn because corn meal is an organic fertilizer and will result in a deep green spot wherever you use it. You should see improvement in 3 full weeks. Organic solutions almost always take 3 weeks to see the difference. You can reapply corn meal as often as you like but the minimum to use for an existing disease is 20 per 1,000. You can usually find it in brown sacks at a local feed store. Cost for corn has skyrocketed in the past 2 years from about $5 per bag to $20. Be sure you are getting ORDINARY corn meal and not corn gluten meal. Ordinary corn meal is the stuff you cook with only when you get it at a feed store, I would not cook with it. It will have weevils in it. Store outdoors. If you don't want to use corn meal, then you'll have to diagnose exactly which fungus it is and find an appropriate chemical. 7 years? Never heard of that. |

| Established fairy ring calls for the big gun. The double barrel 12 ga. Heritage (Azoxystrobin ) used both as a preventative and as a curative. Once you remedy the situation, you can maintain control with Eagle (Myclobutanil) - which is a lot cheaper ... just more preventative rather than curative. Q. Do you have creeping bent or TTTF and where are you at? |
