Can anyone ID what this is on the trunk of my Grapefruit tree and offer any advice on a remedy ?? Insect eggs maybe ?? Seems to have just popped up in the last week or so. Local Extension office has not yet responded. I figured with all the knowledge on this forum I would get better answers anyway.

Any help is greatly appreciated guys. Thanks

That may be a coral spot fungus. Check out the following and see what you think:

Did your tree take some cold damage this winter? This may be a sign of underlying problems.

Thanks Red - and yes it took some major damage. Lost about 60% of the tree. All the dead damaged parts were cut away this spring and now this pops up.

You must be north of us because we planted three trees last year and have no problems with them.
I'm suprised we don't because of the winter we had.

I'm kinda SW of Mobile. As the crow flies about 20 miles north of the Gulf and 3 rock throws to Mississippi. We had some temps down to 12 deg for about a week. The tree is 10 yrs old and taller than my house. This winter the leaves turned white and fell off - that has never happened.

Red you were 'spot on' - no pun intended. County guy just left here - Coral Spot Fungus. Cut the tree down and burn it.

Thanks for the help guys. Damn I hate to lose this tree.

Man, I'm sorry to hear that. I hate losing a good tree.

I may be moving down to Mobile the first of August. It's still up in the air, but there's a good chance I'll be coming down to USA.

Outstanding. If I can help out with anything on this end let me know.

Did he tell you to cut the entire tree down or just the affected branches?

The entire tree. Almost all of the limbs were dead from the harsh winter and pruned back in the spring. Basically all I have is a 12' tall trunk with new growth but the fungus has enveloped the entire trunk from the ground up to about 6' or so.

That sounds pretty bad. I could not tell from the photos.

We lost a satsuma due to the freeze this year. It was only 6 years old but it had just begun to produce pretty good last year. We were hoping to see it perform real well this year, but it is gone. :(

We are only 15 minutes from the Florida line so we are futher south too.

Any chance spraying with copper fungicide helps ?

I use Bonide copper fungicide on my tomatoes to kill tomato blight which i understand is a fungus. It works well. Maybe try it to save the tree ?

Neg. Agent said if it was just on the outer limbs the tree might survive after being sprayed with a copper solution - but once it gets to the point where the trunk is covered in this it will not survive. He did say to still spray it with the copper solution to kill the fungus - spray the ground 5' around the tree - wait one week to cut it down and then burn it. Must be some really bad stuff - do not use for mulch or compost - just burn it.

Thanks for the name of Bonide - I had no idea what to look for. Life goes on - I'll just plant another one.
