EVALUATION OF FUNGICIDES FOR SPRING DEAD SPOT CONTROL IN ULTRADWARF BERMUDAGRASS. Pythium blight on a bermudagrass green during cool, wet weather.

Untreated, Pythium turf diseases can kill large areas of turf within a matter of days.

I did scalp it this spring, but it looked so bad when I did, I set the mower higher when the tops turned green because I didn't want to go back to brown again (dumb mistake). He also told me I had trained my Bermuda too high (2 3/8"), and gave me some advice on how to scalp it and maintain it at a lower height next spring. he allowed for the slight possibility of a fungus, so we sprayed for that today just to be sure.

He attributed it to the last two weeks of 104-107 degree temps, no rain, and my hand watering (no irrigation system yet). His "opinion" was that the brown areas were due to the grass drying out in those spots, and they when I water heavily it stopped further drying and the area turned "dormant." He inspected deep into the areas and tiny bits of new growth could be seen in many areas. He tested the soil for moisture and was good down to about 6", but we had some pretty good rain yesterday.
