Sick trees

Question: Hello there,

I’m wondering if you can help me diagnose some Sick trees… These are northern Pines, they're only two or three years old. It started with one that is now completely completely dead and now the others are following suit.

I treated with a fungicide I picked up at Menards, it didn't seem to do anything, but I ordered copper solution from Amazon, but it hasn't come yet. 

I did notice that my neighbors are beginning to yellow as well.

I am in Cambridge, MN and this is the first year I have had issues. 

Can you please help?

Thank you

response: This web page lists some possible causes. Buying a fungicide or copper without knowing the cause of the problem is not a good use of your money.   https://apps.extension.umn.edu/garden/diagnose/plant/evergreen/pine/needlesmostreddish.html Since your neighbors have a similiar problem, there may be something that has moved on the wind. Are there any chemical sources in your area that may have sprayed some substance on their property that then drifted to yours?  Is the dead grass behind your trees the result of weed spray?  Consult an arborist  https://www.treesaregood.org/ Or submit a sample to the Plant Disease Clinic at UMN, but call them first to see what samples they want to look at.  https://pdc.umn.edu/

response: Thank you for responding! I am not aware of any spraying, I know they did recently spray for some bugs in our city. The grass behind is just field grass, it is an unoccupied field.We have been having problems with voles and pocket gophers this year, worse than I’ve seen in years past. We have a dog that is under a year old and has been digging up the vole trails; he has caught several. I have the picture this app and it was what had diagnosed the sickness And said it could have been stress or a fungus and when I consulted their team, they were the ones that suggested a fungicide. Probably about a month ago, I noticed mushrooms around the one tree that had died, though I couldn’t tell you what kind it was.I also have several lilac bushes that have shown signs of blight this year, most of them drop their leaves very early this year.Amanda Wisner <personal data hidden>On Mon, Oct 14, 2024 at 1:09 PM Ask Extension <<personal data hidden>> wrote:

response: Lilac blight is prevalent this year and is a separate condition from your trees. The shrubs should leaf out normally next spring.  Otherwise I am unable to diagnose your tree problem. The UMN extension educator in your county is not a horticultural specialist but may have heard of some problem occurring in your area trees. https://extensionstaff.umn.edu/katherine-hagen
