Yellow patches in lawn

Rick & Debbie Cook – posted 05 July 2004 14:17

We live in South Carolina and have an established centiped lawn (15 years). Our soil is sandy to sandy/loam. For the past couple of months we have noticed yellow patches developing in our yard – some as large as 10′ to 15′. We fertilize regularly with 10-10-10 and use a high priced grandulated insecticide by Bayer. Two weeks ago we put Ironite on it per instructions but so far nothing has seemed to make a difference. Anyone with anything similar or any suggentions?

Unexplained spots like this, when they respond to nothing, are usually fungus diseases.

You can keep them from happening from year to year by using ordinary corn meal at a rate of 10 pounds per 1,000 square feet every 90 days all year long. You can get rid of the disease once you get it by applying corn meal at a rate of 20 pounds per 1,000. Give it 3 weeks to work.

I get corn meal at a feed store in 50 pound bags for $3-$7.
