Expanding fungus patches

Hi. What do you guys use to treat fungus in lawns? (And for that matter, hedges)
A community for the DIY lawn enthusiast...
Sounds like Large Patch disease; see details on it here: https://www.apsnet.org/edcenter/disandp ... tonia.aspx and https://www.turffiles.ncsu.edu/diseases ... h-in-turf/
Not sure what that might be. You might be able to hit it with a combination of Propiconazole and Daconil; labels will typically list compatible species.
I don't think you NEED to mix in Azoxystrobin for the first 2 or 3 applications of propiconazole. However, you can't expect to apply the same fungicide mode of action over and over again without creating a resistant fungus. So, rotation is needed in the long term. Azoxystrobin is relatively expensive, but the cost can be managed by looking for a split in the TLF Marketplace. Obviously not a great solution when you are looking for a product NOW, but might be to your advantage to get some when a split comes up so that you have more than one mode of action available. Once you have a fungus in your lawn, you can expect it to be a recurring problem when the conditions for an outbreak are met. Ideally, you are getting down fungicide before the weather changes in the fall.SGK wrote: ↑Fri Jan 14, 2022 1:47 pmI found Propiconazole.

Maybe I need to mix in Azoxystrobin as well??
I see DiseaseEx but liquid forms, eg Abound or Azoxy 2SC Select, seem VERY expensive.
