Never use Black Cow bags. Some of it will contain weed killer and its ruined so much of my time and lots of friends I know. I just discovered my problem and have talked to lots of friends with same problem that has no idea they were poisoning their gardens.

Most hay, straw and manure has aminopyralid in it. Aka Grazon. I can't believe Black Cow is sold.

If your plant leaves curl upward.
Short plants
Tomatoe plants look good and bloom but won't produce lots of tomatoes.
Look for the leave curl. It won't kill the plants.

Yep I know several folks who had the same problem. If I remember correctly FurFlyin had the same thing happen last spring.

Glad you posted this ... I used Black Cow in all of my raised beds ... planted right behind it... so far, everything looks good. Now I just have to wait and watch.

I know a horse down the road. Thanks for posting.

You got a link or something for this?

I found this.

Thanks MS. Good to know.

It sounds to me it's like when you get manure in bulk. I have used and am using black kow without a issue.

I didn't, but I composted some of our own manure 20 or so years ago and it had the residual from Grazon in it. I covered the garden in the late fall, turned it under in the spring and grew nothing but corn that summer. It killed every broadleaf garden plant dead as a hammer.

Uh oh. My Beans are showing signs.
My manure pile is on quarantine.

That may explain my tomatoes from a few years ago. They were in pots with black kow. I never could figure out what was wrong with them but they never made tomatoes.

Just days before I learned about this, I saw a man but $180 worth of Black Cow from CT Garvin. You can't tell me that people in the business don't know.

The compost folks likely don’t know. I work in the herbicide business and many times the composter buys manure from places that have fed hay that has been sprayed with one of many products containing a persistent pyridine (as we call them) herbicide. The farmer may not have told who he sold the hay to, or maybe did, but the animal owner didn’t relay to
The composter. The labels used to not allow any hay to move off the farm that was treated, nor manure from animals that grazed fields that had been treated with this chemistry. Corteva changed all that because it hurt their business or they just don’t advertise the restriction to customers.
It may be going back soon, however. EPA is assessing that now.

007 I have a label question regarding FMC sulfentrazone “Spartan” and melons. There is an EPA “master” label that has melons listed as a crop with rates. I called the FMC rep and says it’s not labeled because it’s not the commercial label. If it is safe to use on melons why would the EPA approve it but FMC rep tells me it’s not labeled??

If you ever talk to Stanley Culpepper ask him for me!

I can’t say for sure since I dont work for the, but most likely they had planned to label it, but when they went to the states they did a “print restrict” on that use. It may be they found problems later or just wanted to hold off until they have a better market position. It is hard to say. I’ll give an example of what I have done in the past…we have a product we labeled in all the state, but for market reasons we print restricted it so that only counties we wanted were listed. So, it couldn’t be sold in those counties but we can come back and unrestrict it later if we want to.

I know Stanley well, but don’t see him much anymore, about once a year now.

Dang just planted my little garden yesterday and mixed in 2 bags of black kow. I wish I would’ve never read this. Then I could’ve been blissfully ignorant. Now I’m going to have anxiety.

I hauled six pickup loads of compost about five years ago and put in a raised bed. After planting tomatoes and them curling and turning yellow I finally figured it had manure from
Cattle eating hay that came from hay ground that had been sprayed with Grazon. After I figured that out I’ve planted onions in that bed since. It raises great onions.

My Manure "supplier" had never heard of Grazon, but said the hay he buys is herbicide free. I'm sure he asks, but this seems a shallow comfort.
I don't know the commercial Hay business, but why would a few weeds really matter. The horses will either eat them, or kick them aside. It's a sad
day when even horse pucky has been compromised.

Thanks for posting this Jake.

I'm currently working on building planting beds and a vegetable/herb garden around my house. I bought bags of compost and manure from HD to till into the hard clay. Mixed in 25 bags already for the ornamental planting beds but not the garden area

Before I go any further I'm going to test a few vegetable plants in my amended soil and see if I have any issues.

Damn shame when cow turds are killing plants.

I use it once and was not at all happy with it. Have not used it since. My favorite now is Diggers Delight.

My brother has had a nice garden for the past few years but this year it looks just like those pictures. I asked him if he has used that black cow manure. He said he hasn’t but it sure looks like it. The worst part is he’s always give me stuff out of it. Hopefully his other one will produce.

This is my first year with raised beds and I put some in mine so far no bad signs but I won’t do it next year

no issues with mine so far this year
