I'm wondering as well @CenlaLowell . I could use some guidance as to what type of products can be more stressful to the turf. It seems like fungicides might be less stressing than pesticides...but I'm not sure.

For my own fears, my level of PPE gets much higher when dropping pesticides. :|

@mjh648 , Not so much that it looks like any root fungus/rot. That being said, the entire lawn is just now coming out of dormancy, so most roots are not holding strong including the green areas. As of this morning, the yellowing has not vanished, but it seems to be getting some of the green mixed in so it is diminishing.

I applied some Azoxy about a month ago as a preventative. I'm planning on dropping some Propiconazole this weekend as a fungicide rotation for this cycle. I'm trying to stick with a good rotation of Azoxy, Propi, and Thiophanate-methyl (Clearys) since they are each a different mode of action.

For now, I'm watching how things progress. I'm also thinking about dropping a grub applications, but I'm waiting a bit longer to see if the yellowing areas grow further or die entirely.
I still have it as well. Insecticide is always good to start as I try to keep coverage on the lawn throughout the growing season. I'm going to hold off on fungicide for as long as I can.
What’s the reasoning behind that? Are you concerned all fungicides are growth inhibitors?
Cost saving.... This stuff is expensive. Plus there's people who never spray in my neighborhood and they never get disease so why I'm I getting a fungus issue.

Propiconazle is the only fungicide I can think of that I wouldn't spray on st Augustine.

Azoxystrobin, 3336, and eagle should be your go to fungicides

@CenlaLowell , what is your thoughts on why not Propiconazole? I can’t find a label restriction.

It has a regulation type effect on st Augustine. Greendoc can explain it much better than me and his advice is what I used.

Bio Advanced doesn't give any warnings or restrictions related to that

https://www.bioadvanced.com/sites/defau ... l-10lb.pdf

and yes I do remember Greendoc saying propiconazole was a growth regulator pretty much for SA. Then in other comments I see you in there is a temperature restriction AND HOC requirement possibly.

Will look into Eagle. Only had 1 bag left of the Bio Advanced so no big deal.

I've done several Propi apps on my St Aug so far. I've got a few more apps with the current inventory and will consider shifting off of it then. Thanks for the advice!

OK...dropped the Propiconazole this Saturday night at 1.4 floz / 1,000 ft². I'm letting it sit foliarly until the morning when I drop my last Spring pre-emergent of Simazine at 0.74 floz / 1,000 ft² and water them both in.

OK...Propi and Simazine dropped last Saturday. I'm still having yellowing in the grass as it comes out of dormancy. Overall growth is slower in some areas. I don't think I had this yellowing last year. Roots are still holding, so I don't think it is a fungus. A lot of the yellowing appears to be close to the curb and driveway...but not entirely. :x

I notice the yellowing on cold nights. One day of warmth and it disappears. I'm not sure if you're having the same issue.

@leefjl63, so far it seems to be consistent day or night. Hopefully this will work itself out soon. So far the yellow blades are growing at the same pace as the green ones. I guess I will just have to be patient for now.

This, my yard is still not all the way grown out. I'm thinking the ice storm knocked alot of my turf back.
