Tough weed

[showcrop]

Just off the top of my head, your mix is too weak. I think it should be 4-6 oz to the gallon for handheld sprayer. Read your label. You also may want try Crossbow, it is for woody species and works on tough weeds, too. I agree with the waxy leaves needing a surfactant to prevent spray run off. Mark.

I read and followed the label instructions. I am seeking advice on going stronger than label.

at least 3oz to gallon of ru. add crossbow and best at this time of year.

As waxy as those leaves are, you could probably spray full strength and not get enough absorption without something to break though the wax.

If you read through you will see the discussion about that.

Picture of my 1010 dozer.All the weeds were cut away this spring,I was going to fire it up and sell it.I didn't get to it,and 5 months later this is what i have.The wild rosebush behind it always jumps out of the ground,but that bittersweet makes it look lazy.The vine over my stack is holding it shut.

Wow what a mess.

That weed looks like it has waxy leaves.
Put some Dawn detergent in with the herbicide to make it soak in better.
I use Dawn all the time when I am spraying with glyphosate.

The directions on the Glyphosate container tell you that using a "surfactant" (soap) improves the ability of the material to kill the plant.....surfactants are cheap, takes like 20% with 80% Glyphosate making up the 2 or more % of the mix added to 98% water......all on/attached to the container.

I have a weed that appears to be some sort of ivy, that is not in the least affected by 41% glyphosate mixed at 1.5 oz to the gallon. Should I just mix stronger?

I had a lot of poison ivy growing up the sides of one of the corn cribs. I found that Brushtox from Tractor Supply did the best job on it out of anything, without killing any grass. I also used it to successfully eradicate trumpet creeper vine around one of the electric poles. If it works on that, it probably will work on your target.

I have been using Round up, or the generic equivalent, 41%, and always mix close to 6oz per gallon. I remember reading that rate / mix a long time ago, and continue to use it at that rate. But for tough weed control I prefer Crossbow, and again on that plant, a surfactant. Mark.

Remedy works too on Poison Ivy and other undesirables without hurting your pasture grass....but it was pricy at the local feed store. $99/Gallon, mix 2% plus surfactant.

Started on experimenting with my doggone Blackberry bushes. Need a game plan for next year.

All quantities are oz. per gallon, in a one gallon sprayer.

2oz Crossbow...........2oz surfactant

2oz Remedy..........2oz surfactant

Commercially available 80/20 surfactant used.

Like a fool, I didn't write down the date. It was approximately 2 days before our rains came. I'm calling it 9/23/26.

For the few days I moved hay, I saw very little difference, other than the leaves folding a bit. I haven't observed the plants since it rained.

Spraying was early morning, temp around 75*, very light wind. One note........we are in a drought. The rain that came did little to relieve it.

Ag Extension literature recommends spraying Blackberries in the Fall after the fruit drops. There were no Blackberries this year, but I don't figure it matters. Extension literature, and other literature, suggests that this plant starts moving nutrients down to the roots at this time of year, making it the ideal time to spray. Some articles also claim that Spring, while the plant is actively growing, is also good. I need to look up the articles again.

I'm expecting better results from the Remedy. It's around 60% Triclopyr..........................Crossbow is mostly 2-4-D with around 30% Triclopyr. Triclopyr is the main active ingredient that goes after woody plants. Or, so I understand. I'll link to some articles later.
