    I am seeing these in my lawns. The tech that treats my lawns says it's due to the extended damp cool weather we've been having. Says there is nothing to worry about... It'll will grow out.

    True? How do you treat these diseases? A little nitrogen boost?

    Usually nitrogen is the 1st thing to try. We had one get bad enough last year that it actually killed out about 500 sf of Zoysia. If the nitrogen doesn't do it or it gets worse, a chemical treatment will be necessary.

    it is important to maintain adequate amounts of nitrogen, phosphorus, potassium. Make sure to irrigate the turf deeply and infrequently as well. You should also remove the clippings to avoid additional infection.
