Atrazine and Trees

Just wondering how many of you have seen problems with trees and shrubs in your yard after using Atrazine. I had some trees planted and the guy asked what chemicals I use on my yard. He said don't use anything that ends in ZINE that it was not good for the trees.

Hopefully, one day, the Environmental Protection Agency will appropriately ban this product.
In my limited use, and for the weeds that bother me the most, this stuff has been fantastic. If it ultimately kills my River Birches, then....Yay!

If my shi-shis die, I will be bummed.

Atrazine is one of the most environmentally damaging chemicals you can use.

I spray them around my crepe with no problem at all

One application should not do much harm unless they are newly planted. Annual treatments on the other hand will absolutely kill your trees eventually. Even live oaks.

No pesticides are good for any plants that have not established itself.
Randy Lemmon lost me at the title when he's recommending weed and feed in general.
I made Atrazine for 12 years. I'm not smart enough to know what makes Atrazine any worse for the environment than MSM, 2-4-D, Dicamba, or Pendimethalin, but I don't think the list of people who are smart enough, are on garden radio, peddling weed and feed.
If you want your yard to look like Augusta National you're going to need some help chemically, don't like chemicals, then plant your yard with native prairie grasses and wildflowers for pollinators.

Randy never recommend weed and feed. He just says have you ever read the label on the bag.
I use chemicals on my yard but when the tree guy told me not to use it. It just made me start doing some reading and I ran across that article from Randy and know I’ve seen info from his site on here before and it just made me wonder if atrazine was effecting anybody’s trees because I know it’s brought up on here a lot to use it.

I’ve used it around oaks, magnolias, holly, crepe Myrtles, vitex, and gardenias, without noticing any negatives. Most were fairly established, but if they weren’t I mulched out to at least the drip line so I wasn’t spraying that area. Most of the bad wrap is coming from the Ag practices of spraying over tens of thousands of square miles, same as with glyphosate.
Your tree guy could also be CYA’ing. It’s unlikely that the strength or application rate a homeowner would have access to would cause more harm than transplanting and disturbing a potentially root bound tree.
