Fungicide Treatment

Our Turf Programs accomplish a great deal of disease prevention without the need of fungicides by keeping potassium levels high, avoiding the overuse of nitrogen and pesticides, and minimizing thatch levels.  However, fungicide treatment is still sometimes necessary.  A turf manager can diagnose the specific disease, advise you on good cultural practices and provide corrective fungicide treatments if needed.

Some of the common lawn diseases found in the Atlanta area are shown below.

Spring Dead Spot

Spring Dead Spot is common in a number of popular Bermuda cultivars.  It is a disease that appears during Spring transition and usually goes away during the Summer.  It can be avoided with good cultural habits, but timing of pH adjustments, nitrogen applications and fungicide efforts are all factors in the successful control and prevention Spring Dead Spot.

Brown Patch

Brown Patch is most commonly found in Tall Fescue turf in the Atlanta area, but it is also common in St. Augustine turf.  Cultural practices, such as over Nitrogen use, evening irrigation and mowing too short can increase the likelihood of infection.  

Fungicide control options have improved in recent years, especially when treated early.  The turf in this image was treated twice, but was almost completely clear of any sign of Brown Patch by the 2nd treatment.

Zoysia Patch

Zoysia Patch is similar to Brown Patch, but tends to appear in late Summer to early Fall and won't show the same plant symptoms on the leaf or stem.  Good cultural habits play a major role in the prevention of this disease, but frequent afternoon rainfall and cooler temperatures can be enough to cause this disease even when good management practices are followed.  

Fungicide control options are successful if applied at the right time.

Slime Mold

This is an example of a non-damaging fungi, which should not be treated with a fungicide.  Slime mold often appears during cool, wet stretches on warm season turf, usually in areas with excessive thatch.  It typically goes away within 1 to 2 weeks.

Knowing what does not require treatment is a valuable aspect of the service we provide to you.
