Herbicides in orchards?

[KY wild]

I have had several lessons from my tomato plants when it comes to chemicals. Several times I have tried to kill something with 2-4 D and injured my tomato plants. It did not take a bad wind or spraying wildly to harm the tomato plants, any spraying within 20 yards or so can cause injury it just a matter of how much disfiguration is caused. So now I need to get rid of a very big crop of mares tail in my pear / apple orchard and not for sure how to go about it. My trees have 5 foot tubes on them and I would avoid spraying any fruit foliage but I am still paranoid 2-4D will harm them. So are fruit trees sensitive to 2-4 D spray like tomatoes or can I spray carefully and successfully. Finally if 2-4 D is a no no then what is my other options of spray to Kill mares tail? Thanks in advance

2,4 D has residual soil activity. IT does harm trees, especially when overdosed. Saw liberty was an option for roundup resistant marestail.

Have you tried roundup? Maybe mow, then do roundup a week or two later, when its young and more vulnerable.

Got no experience with liberty.

2,4 D has been used in orchards. I have no experience with it. Saw an article of what is used to control ground vegetation, they listed how common they were. IT was on the bottom of the list. Article mentioned it was in california, might have a specific weed they need to combat.

I had marestail everywhere in my orchard. Let it grow til it flowered and then mowed it. Repeated as necessary. Now I can't find a single one in the orchard. It fixed whatever soil condition it was trying to correct.

It’s gone for me with a couple mowings, overseed in fall with rye and more clover, mow the following May and it’s not an issue.

What is called mares tail may vary in different parts of the country.

I suspect I have looked at a different plant than you.
Soil pH may be a factor in what I see.

Perhaps do a soil test. I do not see it where I mow but in corn plots.

If you spray your trees, clover isnt a good idea. Killing bees. Onced i was taught that, stopped frost seeding
