| Hi All,
Did some searches and I think I may have brown patch of dollar spot fungus in my lawn. I'd like to get it under control before spreading too much. Lawn has been recently fertilized, so would a fungus control be appropriate? Down below are some pictures. Any help with the diagnosis and treatment is appreciated! http://i46.tinypic.com/2ih1put.jpg

Fungus of some kind. I agree. How are you watering? How often and for how long? So yes, fungal control would be appropriate. I can't help you with chemicals but if you wanted to do it organically I can tell you what works for me. I wish I could say it works unequivocally but some people I trust highly have not had the same luck as I have. If you want to try the organic approach you cannot use any fungicide first. You have to use the organics first. Why? Because the organic approach relies on a predatory fungus that will sweep in to prey on the disease fungus. The organic approach is ordinary corn meal - yes the stuff you buy at the grocery store. However, most people prefer to buy it in 50-pound bags at a feed store to get a much better price. The application rate is 20 pounds per 1,000 square feet. As I get more feedback on how this works, you might want to plan ahead to reapply at the same rate in 3 weeks. There is a fungus that decomposes the corn meal. The predatory fungus will attack the fungus on the corn and grow tremendously in population. When the original fungus is all gone, the predatory fungus will continue to attack the fungus causing your turf disease. By applying a second dose in 3 weeks, you magnify the population of the predator considerably. |

| Looks like red thread to me. Corn meal might work as a preventative in the future, but it's probably not going to do anything to combat what you have now. |

| i am willing to bet that 1. lawn was overfertilized 2. Lawn was mowed when wet or dewy 3. fungus is pythium blight i hope i am wrong as only very expensive chemicals will kill it. Research and see if photos match. those chemicals can be applied by a good lawn company or bought on ebay. you will not find them in any retail store and nomal fungal treatments found there are useless. |
