Has anyone found a way to rid a hay field of milkweed and dogbane?

Question

This year a neighbor gave 26 acres to me to take hay off.  All I had to do is add inputs as needed.  In the past these fields were cut for mulch hay and the weeds would just add bulk for them.  I knew I wouldn't take hay this year but I have been mowing it before the weeds go to seed..  The milkweed and dogbane are scattered in some areas while others are large sections.  I haven't found any herbicide that actually works.  Any ideas?

Answer

Don't know much about hay but won't 24-D work?

Answer

Higher rate maybe? We had E3 beans this year and absolutely nothing survived even the lower rate of enlist which is just safer 24D

Answer

I used the highest amount recommended for hay/pasture.  Maybe after a couple of applications in the spring and fall it mightwork better.   Thanks for your response

Answer

2-4D with Banvel. will take couple 3 years on the Dogbane. .plus I started a couple years ago using 1-2 quart of ProwelH2O in early spring with nitrogen application. .If u apply Nitrogen after 1st cut do 1 quart  early spring then 1 quart after 1st...not the cheapest but if you sell 2nd cut you will easily see your ROI..or if your feeding all your hay you won't be spreading weed seeds.all.over your farm..I havn't found any 1 and done approach but the 2-4D with Banvel is best way I found to get started at it...it'll take a couple  years staying after it. .good luck

Answer

Thanks.  I'll look into these.  I sprayer crossbow two weeks ago and looking at it yesterday the leaves looked like they took a beating but the stem kept growing and produced nice Green leaves above the sprayed one's.  Grrrrr

Answer

I looked in my when weeds talk book and it seems if you address available calcium it would help with the milkweed. You could try adding 100lbs of gypsum per acre. If nothing else the sulfur will help your hay.

Answer

I haven't heard that before.  I already added enough liquid calcium to raise the ph from 5.5 to 7.0.  Hopefully that will help next spring.
Thanks

Answer

My brother in law tried remedy herbicide. He felt like he got the emerged plants with one application put had new plants on the fringes of the old patches. If you're not selling the hay or concerned about residual carryover, I like grazon for most broadleaf problems.

Answer

Add a non-Ionic surfactant with your group 4 herbicide of choice and you will curl them. It is also beneficial to spray before the weeds reach reproductive stage.

Answer

It doesn't do much except brown the edges of the leaves.
