Brown Patch/St. Augustine

Just today we noticed what appears to be brown patch on our lawn. We have watered every other day during the drough. Lawn was green and healthy until this morning. I read where cornmeal is good, but do not know where a feed store is in our area. Would regular corn meal from the grocery store do any good…..any other suggestions before it gets out of hand. Thanks

Thanks for the suggestion of “Azoystrobin”,never heard of it. Do you know wher I cansecure it and how it is used on the grass?

any professional chemical distributor such as “John Deere Landscapes”Azoxystrobin is the active, a trade name you may find it under is “Heritage”You have to spray it. Will give you about a month of residual control.

Heritage is great and I use it on a rotation of Clearys and Eagle fungicides. Heritage is $600/lb. I’d start with the Eagle combined with Daconil which is not labeled for residential lawns but you can get a residential weaker mix at Tractor Supply. The “Strobins” will NOT cure brown patch but are great for root uptake to prevent it. The Daconil and “other” fungicides are for treating already infected brown patch. You’ll need to spray the Daconil several times. When you water make sure that you are irrigating as early in the day as possible so that the turf has a chance to dry off to help prevent the fungus from developing. The heat of the day steams the water and fungus appears. Another important factor is to let the soil dry out sometime during the week by skipping a day or two of irrigation.
