Ortho posion ivy killer

[furb]

Long story short I sprayed posion ivy killer on posion under my dogwood tree and now it looks like crap. Tree is pretty old, twenty years old? Is it weed killer killing the tree. Could be the hot weather as some of the other trees look wilted. Thanks in advance.

The main ingredient is probably triclopyr, in which case it would be exactly what is making the tree look bad. 50/50 if it makes it or not, hard to say without knowing the amount applied or seeing it.

It is tryclopyr, triethylamine salt .7%. About 10oz within 10' of the tree. I tried to keep it just on the posion but...

Anything to try to nurse the tree back to health?

The roots are probably just taking up residual. It will pass. Just make sure it's getting adequate water, not too much and not too little. Maybe consider a late season application of a slow release fertilizer. Blood meal is a good choice. Follow the recommended rate for trees.

Ok thanks

How warm was it when you applied the product?

Around 70 degrees maybe a bit cooler

Last summer I applied ortho weed killer to some weeds around a black walnut in my yard. Said it was safe for trees. A week later the tree dropped all it's leaves. Thought it was dead, but I left it just in case. This spring it came back with a vengeance. Completely fine. I know it's a different species and product, but they can bounce back.

That stuff is very volatile. The fumes or mist may have went up and hurt the tree. Unless you soaked it . It shouldn't have any activity in the soil.

You may have mixed to strong and over applied. 10 ounces of product may be enough to cover an acre.

In my situation there were exposed roots in the weeds I was spraying. That's was my fault, but it said it was safe for trees.

It probably says to keep off of the trees though, right? Triclopyr does go through bark - usually with a bark penetrating oil, so it does not surprise me it was taken through roots.

I didn't read that far. "Safe for trees" was good enough for me. Honestly I wouldn't mind taking the tree down, but the wife likes it.

If you mix triclopyr with diesel, it will go right through the bark (look up "basal bark spray")..............I'm just sayn'

 

[Brendon Phillips]

Hmmm.... I'll keep that in mind.

10 oz. ? that seems like a lot of product but since when has a homeowner ever read the label.
