Red Thread Disease

Right now in the rough there are areas that have a tan look to them with a reddish tint on the leaf tissue. That is red thread disease, a disease that we have every year in June and appears more when we have wetness from rains.

Red Thread Disease

It really doesn't concern me to often because it does not injure or kill the plant.  It is just on the leaf tissue, makes it a little off color, and as soon as things warm up and dry out then it will disappear.  Different disease all have a different threshold level with me.  Ones on greens or low mowed areas that kill the plant have a very low threshold and I spray when we see them, ones like this and being the rough, it really needs to spread a lot before I go out and control it.
