Randy Lemmon is our local plant expert and radio personality. He says cornmeal is ineffective on Brown Patch. Seems there are only chemicals that will kill Brown Patch or Take All Patch. The thing is, if you don't kill it, it lives in the soil and will return each year. It seems only fungicide chemicals will do this. Brown Patch won't harm the lawn, it's just ugly. Seems to be true since we battle it yearly. They are bringing back a 17-letter chemical fungicide his year but it will be too late for this season whenever I find it in stores. Take All patch, however will take over and make you replace both lawn and 3" of soil. It takes a different chemical all together. All this fuss from the rain we prayed so hard for!
