View Full Version : Grey Patches 6" diameter on lawn
05-18-2007, 12:29 AM
Grey patches are starting to form on the lawn. It has been raining pretty heavy the past two weeks. the two regions with spots are isolated to areas with mild shade (under trees) throughout the day. The patches are increasing in number in these two areas.
Fertilized about 2x yearly
Will have pics tommorow, but looking for a diagnosis and treatment procedure.

Probably dollar spot due to excessive moisture on the leaves and lack of nitrogen.It will keep spreading and your mower can spread it as well.
A fungiced won't help at this point,but can be applied to prevent further damage.
To repair the problem,aerate the lawn and apply 1 lb of nitrogen per 1000 sq ft.Only apply water in the morning,so the leaves can dry during the day.Of course,you can't schedule the rain,but this is what works to keep dollar spot from occuring.
Get on a fert plan for your bermuda.1lb of nitrogen per 1000 sq ft,every month, during the growing season and don't water every day.

There is heavy dew every morning. I have not been watering by using sprinklers b/c of this and the rain.
I will apply a fungicide to the rest of the area to prevent spreading and fertilize. I have been trying to just mow the effected regions seperately then doing the rest of the lawn later.

yep,dollar spot.If you look at the leaves,just outside of the effected area,they'll have an hour-glass lesion on them.You may need a magnifying glass to see it well.
