How To Treat Take-All Fungus In Bermuda Lawn

Filed Under: Lawn Care, Diseases and Fungus, Techniques & Methods · Keywords: Control, Treat, Take-all, Disease, Fungus, Bermuda, Lawn · 990 Views
My poor bermuda lawn has been diagnosed with Take-All fungus according to UGA (University of Georgia). They recommend discontinuing any high nitrogen fertilizers which will feed the fungus and treat with active ingredients Myclobutanil (such as Immunox Lawn Disease Control) or Triadimefon (such as Bayer Advanced).

I core aerate my lawn every May and get it treated by a local lawn care company 8 times a year. I'm thinking of discontinuing the lawn care service to I can organically treat my lawn to get it back to health. I was reading an article (http://www.randylemmon.com/lawns/gardenline-takeallpatch.html) that says to do the following steps:

1.) Core aerate to get oxygen down to the roots.
2.) Spread agricultural cornmeal at a rate of 2 lbs/100 sqft
3.) Apply Actinovate or a good compost to introduce more microbes.

Anyone done this or seen or heard any success with this? If so, where do I find agricultural cornmeal and a good source of compost in the Conyers or Atlanta, GA area? I'm waiting to get the results of my soil test to determine the pH, NPK, calcium, etc.

Answer #1 · Gardenality.com's Answer · I haven't had any firsthand experience with Take-All disease is lawns but have done some research for a few customers that have come into our nursery with the problem. From what I can gather there are several things that can cause the disease and there are both cultural and chemical methods for prevention and control.

Poor drainage of soil due to compaction or low-lying areas that tend to stay soggy or wet. Core aeration and adding sand, and filling low spots woukd be helpful.

Irrigating too late in the evening or at night can cause problems. Water only in the morning and only if necessary. Water deeply less frequently rather than every day.

Some research has suggested that the disease thrives only in alkaline soils. If your soil test comes back and indicates a pH above 6.7 add soil sulfur to increase acidity.. But then Bermuda grass thrives in a slightly acid to neutral soil so don't make the soil too acidic.

Other studies have shown that manganese deficiencies can cause the disease. So applications of manganese sulfate has shown to be an effective method of control.

Fungicides can also be helpful in controlling or preventing the disease. At our nursery in McDonough, GA we stock a product made by Bonide called INFUSE. Take-all is one of many listed disease on the product label that this product will prevent and control.

Keep us posted as to the soil test results and any methods of control you try and how effective these are in controlling the disease.

Let us know if you need more details or have any other questions.
