Attachment 199424Hey all

A few months back a sprinkler broke an drowned out a patch of my st Augustine. I removed most of the dead patch an restored the area with some plugs.

See pics. The brown patches are now spreading. Any advice how to treat this?

Thanks!!!!!

First you need a fungicide.

Then you do "cultural controls". This means taking care of grass in a way to inhibit fungus growth. This link explains it pretty well.

Sorry Folks...I need to revive this topic.

I went to my local nursery with the photos looking for a fungicide. The resident expert is sure its chinch bug and not fungus.

He stated st Augustine fungus/brown patch is not common in southern California (specifically riverside county).

So I treated for bugs today and will repeat in August as directed.

Is there any harm going back and getting a fungicide as well? Just treat for both.

Your local resident expert is not correct. Brown spot (fungus) is prevalent most everywhere. When I lived in So. CA we had it nearly every year. Especially after heavy rains. And yes chinch bugs can cause browning but your patterns indicate a fungus. Possibly you have both problems, but...
And it never hurts to use a fungicide.
Read the following web site for more info on brown spotting.

Thanks witnit. Do you recommend a specific brand fungicide?

Also, should I remove the brown patches before treatment?

Yes it's best to remove as much dead grass as possible, generally by raking it out.
Fungicides such as Bonide, Bayer, or Spectracide work well. Follow their directions.
Fungicides can be difficult to rely upon for controlling brown patch in the home lawn, but regular applications can vastly improve appearance. A good “rule of thumb” to follow on warm-season grasses is to initiate fungicide sprays when nighttime low temperatures reach 70 F. Stop applications when nighttime lows are forecast to be below 70 F for five consecutive days. Typically, applications are made at 14-day intervals. If problem persists contact a professional service.

Additional information for all warm weather areas.
Avoid high nitrogen rates on warm season grasses in mid to late fall. The brown patch fungus readily attacks the lush growth of grass which nitrogen promotes.
Irrigate grass only when needed and to a depth of 4 to 6 inches. Water early in the morning. This disease can spread fast when free moisture is present.
Avoid spreading the disease to other areas. Remove clippings if the weather is warm and moist to prevent spread to other areas during mowing.
Keep lawns mowed on a regular basis to the proper height for the grass species you are growing. Prevent excessive thatch buildup.
Provide good drainage for both surface and subsurface areas.

Thanks again!!!

Looking at photos of brown patch disease has me thinking the problem could be ‘take all root rot’

My problem area is small and spotty dead patches.
