Good evening fellas',

Running into a slight fungus problem here in the Orlando area with St Aug. My next door neighbor just had new sod put in per HOA (he let it deteriorate beyond belief). Sooo, he's got the sprinklers running 3x a day, 1hr a zone, and I'm starting to get some rather thick/unusual brown patches and what appears to be some type of fungus near my backyard, and side yard.

Watching YouTube videos, (few of the usuals here as you can imagine) and ordered some Eagle 20 fungicide which will be here tomorrow, however, I probably should have asked this question prior to ordering the Eagle 20 - but, I'm here now, and starting my first thread.

Front yard:



Side/Backyard:











Main questions - will Eagle 20 (probably in two applications?) take care of this fungus and second, should I do any type of raking in/around these areas to pull all the dead/super moist thatch up or just leave it?

Appreciate your time, and thanks for your response. *cheers*

is eagle 20 labeled for gray leaf spot in SA? If it is, you're probably gtg. Raking it out is totally up to you.

Yes it is. If I remember correctly 1.2/oz per 1k. And if that is indeed "brown patch" not too sure, based upon the pictures I've seen of what is called "brown patch", Eagle 20 covers both at the same recommended dosing - 1.2oz/1k.

That looks like gray leaf spot. Yeah eagle 20 is labeled for it. Here is a article on gray leaf spot and some other things you can do to help. https://hgic.clemson.edu/factsheet/gray-leaf-spot-on-st-augustinegrass/

I'm currently fighting it in my st Augustine. With all this late afternoon storms and humidity it's fungus growing heaven. Best of luck to you.

Amen, brother!

How has the fight/battle been with you, and what have you done, if anything besides applying Eagle 20? Have you applied or done anything different, or is it a simple waiting game?

Furthermore, how often are you applying? I'm probably going to shoot for every 10 days (depending on weather) to 14 days. Again, with his sprinklers running almost non-stop I don't know it I will win this summer, but maybe control it from getting any worse until he slows his watering.

Just applied my first application this past Tuesday. Going to shoot for 14 days depending on weather. I have been bagging my clippings and started mowing at 3.5" instead of 4" hopIng the shorter height it may dry out faster.

10-4. I have to cut here soon, probably tomorrow or Saturday, again, weather dependent. We had one of the worst rain "sessions" I've seen all year here, today, but was over in about 1.5hrs.

Bag, lower the mowing height a hair and apply Eagle 20 tomorrow. Guess I'll keep this thread posted for others/general purpose. :thumbup:

Are you "spot" treating" or blanket applying?

I did blanket app. To help prevent it from spreading more.

 

[iFisch3224]

Slightly more than 1.2oz per 1k (4oz per 3,300sq ft)

Mowed 3.5" with the Honda HHR216 and bagged clippings. Hoping for the best! Actually turned off my neighbor's sprinklers tonight/tomorrow (he's in Brazil) that just had the new sod installed, so this app can actually dry. Past 48 hours have been sprinkle/light rain ALL day.





The back/side yard really needs it as that's where most of the excess water is coming from, but also notice it in the front yard as well.

Nice thing I took pictures, it appears my rather new(er) blades need a sharpening too (less then 1 year old, or almost).

I've been dealing with this in my St Augustine as well I've used propiconazole 14.3 class 3 next I'm going to spray 3336 F class 11 hopefully after all this all this fungus will be goie. I have noticed a big difference after spraying propiconazole 14.3 though.

10-4. Would it be advisable to go to a class 11 after my second or third application, if necessary, or try Propiconzole 14.3 as another class 3? I've read you're supposed to switch it up (class 3, then 11, since 14.3 is a different chemical not sure if I should go glass 3 w/ different chem or class 11 all together), but at ~$40 a bottle, I'm going to make a few applications before buying another bottle, lol

Yes you are supposed to switch it up due to the fungus creating a tolerance for the class 3 chemical. Yes, all this pretty expensive quick.
