    One of our bigger accots we cut and spray. Its berumda and its right i front where everyone gets to see it. Around 20k more in back and no signs. Only in the front under a huge oak. Any suggestions on getting it under control.

    You sure it isn't spring dead spot? Looks like SDS to me.

    Been too cold here for brown patch. Id say spring dead spot.

    Try cutting a little shorter and increase fertility.

    Think if you do a fall fungicide as it goes dormant you can prevent it.

    You need to get a soil sample tested and find out for sure. Guessing is not the way to go here. Brown patch is like a common cold, SDS is like cancer, cost-wise.

    That is SDS. Brown Patch/Large Patch rarely affects Bermudagrass. Only under extreme conditions of humidity and temperature being just right for the disease. Your chemical guy calling that brown patch is like a greenhorn customer calling Dallisgrass Crabgrass because it is shaped like a crab :laugh:

    Reducing nitrogen rates late in the summer and early in the Fall will help reduce the occurrence of the spots the following spring. That being said, customers who want to have their lawn green as a gourd until frost usually suffer the worst damage if their particular cultivar is more susceptible to the disease, and yes, the cultivar of Bermuda does make a difference.

    Rubigan is the only fungicide that'll work and the timing of the app is critical. It is extremely expensive also. I tell customers to mow shorter early in the season and also mow frequently to encourage the spots to fill in ASAP. That is about the only practical thing you can do...
