Help with Dogwood Fungus
Posted on 8/10/25 at 8:39 pm

Several of my Kousa dogwoods have contracted Anthracnose and I’m looking for advice on how to deal with it. At first I thought it was sun scorch so I didn’t think much of it but others have got it now and it’s looking bad. I I dug in to it more and it looks like this is what it is. From what I have read it looks like I need to remove as many bad leaves as possible, spray an insecticide and fertilize? I am looking at buying armada 50 WDG fungicide but not sure what kind of fertilizer to help leaf recitation/growth and help with the overall health of the tree.

All of the natives have died or dying, from the forests to home landscapes. Google it. You see almost none of them in bloom in the spring in the understory of forests.
It seems there’s some labor intensive and expensive way to keep them alive, but they eventually succumb. Kousas are not native, but I suspect they’re having the same problem.

We've been on the lookout for it at our place in Virginia for a couple of decades and have not seen any meaningful issues yet
Here's a great link outlining the disease and traditional management including fungicides
LINK
I have been using Propiconazole fungicide every three or four years on my live oaks using chemjet injectors and found it they seem to respond with better growth and healing over some chronic wounds
They look like big 60 cc syringes with a cylindrical plastic tip instead of a needle. You drill a hole through the bark, insert the tip of the syringe, will be snug, and release the spring loaded plunger. Wait 10 minutes to one day or longer until the concoction is infused. Deliver a 50/50 Propiconazole 14.3/water solution every 3 inches or so around the circumference at chest level
I have five syringes so it might take a few days to work my way around any given tree
I have also used them to inject Roundup into trees and shrubs I need to kill, insecticide into non- flowering trees prone to webworm and other caterpillar damage, andPropiconazole into other trees prone to fungal damage, with excellent results
I think injection into dogwoods would be "off label", but Propiconazole is listed as one of the controlling agents,
Other fungicides may not be amenable to this technique due to being oil-based? or some other chemical incompatibility, but I would explore that so that you could rotate amongst the different fungicide groups to avoid resistance
If I had a handful of dogwoods that meant something to me, that's what I would do

Years ago had 21 native dogwoods on Northshore.
One by one every one of them died.
10 years later planted 3 Kousa and they died.
Used to see them on sides of I-55 and in the woods near Vicksburg
All gone now

I wonder if it is worse in the deeper south. When I moved into my house in br 20 years ago, we had three 15 ft dogwood in the front yard, one almost dead, one halfway there, and the other fairly healthy looking. 4 years later they were all gone
