Dear YT,

Thank you very much for your inquiry. While I will be the first to say I cannot exactly pinpoint your issues without a few pictures (even though you did a great job of describing the problem as best you could), I can also say to not be too alarmed. First, see if mowing the turf and substance off helps. This will help to prove it is a blip on the radar. Zoysiagrass is most susceptible to brownpatch, rust, and leaf spot (it does not sound like any these are your issue). I would do nothing at this point to see if the rain is the main issue (combined with high nitrogen release from organic nitrogen sources). F you could send a picture of the total affected area and a close-up, it would help tremendously.

Again, thanks for the question and let me know if you have more.

Respectfully

I checked this morning and it seems to be disappearing. You can barely see the spots that were white and that substance appears to be simply falling off the blades (though some of the blades are a a dark olive color). I'll keep it mowed down for the next few weeks and see if that does the trick. Thanks for the "don't panic" tip and if it comes back I'll post pics.

Also, I play softball for your sponsor, we even have jerseys in the same color as the shirt you are wearing in your picture, minus the collar of course. Are you located in the Auburn area?

YT,

The company I work with is located in Milwaukee, I am in Michigan.
