brown patch – fungas?

Hi! I have dwarf bermuda grass on my golf course greens and I have noticed on some of the greens on certain areas of the greens large numbers of small, irregularly shaped circular in appearance, brownish almost greasy looking spots on the greens. Any ideas whether this is a type of fungas? If so, what type? Thanks. Mike

Use some Pro-Star, but are you sure it’s Brown Patch. Be more detail on the shape. Is it in a circle pattern about 2-3″ wide with the middle still green, if so it’s Take-All-Patch. If it is Take-All-Patch use Banner Maxx or Ammonia Sulfate.

Hi! Thanks for the help. I’m not sure it is brown patch. I was guessing at what it might be. The irregular circled spots are about 2-3 inches in diameter and they all look like a brown, greasy spot on the green. Almost as if someone had dropped oil in spots only not as dark. I think I have seen the other thing you referred to, although, I have never figured out what it is. It looks like a halo almost with the circle being about 6 inches in diameter. The inside is green, but the circle itself is gray or white looking. It has been noticable on one green and seems to reappear every year, especially in summer. What do you think? Thanks,

Mike

Sounds like you have pythium blight. I just sprayed my zoysia for the same thing. I used Dithane. Fungicides are expensive so get ready.
