1. BioAdvanced 704655A Brush Killer Plus

When it comes to herbicides, there’s not much innovation to do. At least that’s what we believed for some time. But things have changed nowadays. And the BioAdvanced 704655A Brush Killer Plus is one of the agents of change.

So, what’s so innovative here? Well, this non-selective contact weed killer has brought in some extra features with its efficient killing method.

For starters, the herbicide is water and rainproof once it sets. So, while applying this, you just have to make sure that you get a 4-hour window. After, that you can be tension free as the herbicide will strike a swift blow of death to those blackberries.

2. Remedy Ultra Specialty Herbicide Weed Killer & Brush Control

In general, Triclopyr works as a contact weed killer. Which means it only kills the top part of the plant while keeping the roots intact. As a result, sometimes the weeds start growing again. But our herbicide here gets the best of both worlds.

This uses triclopyr but also reaches the roots. And the best part is it acts fast.  So, what else does the Remedy Ultra Specialty Herbicide Weed Killer & Brush Control offer?

Well, this long-lasting flexible weed killer works at a low odor. So, your pets won’t go out of control after applying it.

3. Southern Ag 100520254 Crossbow Specialty Herbicide

At number 3 we have another non-selective contact weed killer. The Southern Ag 100520254 Crossbow Specialty Herbicide is like a small pepper. It looks small in size but it can perform miracles.

For example, with this herbicide, you can make up to 96 gallons of solution. And every drop of those 96 gallons will work on killing weeds effectively. Moreover, as it’s a contact herbicide, it can deliver results pretty quickly too.

Overall, this one would be a great choice if you want to clear up your large yard.

4. Ortho GroundClear Poison Ivy & Tough Brush Killer

5. Green Gobbler 20% Horticultural Vinegar Weed Killer

Enough with the chemical herbicides. Say hello to the first organic herbicide of the list. The Green Gobbler 20% Horticultural Vinegar Weed Killer starts working instantly after getting in touch with the plant.

Now, don’t confuse it with the regular vinegar. This weed killer is 4 times stronger or more potent than our regular vinegar. So, this herbicide can easily burn down your blackberry plant. And because of its organic quality, it can kill those weeds without harming the environment.

6. Weed Slayer Organic Herbicide Natural Grass and Weed Control

It’s surprising to have 2 consecutive natural herbicides here. We were surprised too. But it looks like the Weed Slayer Organic Herbicide Natural Grass and Weed Control is packed with useful features. And with those features, it grips is position firmly.

Although it’s organic, surprisingly it’s a systematic weed killer. So, how does it work? Well, it uses Eugenol. A substance that’s derived from the essential oil of cloves. When you apply it in the weeds, it gets absorbed by the plant. Once inside, the herbicide starts working on killing the weed.

But that’s not everything this herbicide has to offer. So, let’s take a look at the pros and cons to get a deeper understanding-

7. Crossbow Herbicide Dow Specialty Herbicide

We’re back to the triclopyr based weed killers again. This one is like a go-to herbicide for gardeners. It’s got all the basic features and all. And those have maintained a good industry standard. However, the Crossbow Herbicide Dow Specialty Herbicide lacks a magical touch.

It’s like you can keep this as the standard and look at the others for added or reduced features. For example, in some, you’ll see an included nozzle. And some won’t kill weeds that effectively. And choosing those depends on your preference.

But if you’re someone who just wants a selective contact-based herbicide, then you can go for it. It’s made for one job and that is to kill weeds.

8. Image Brush & Vine Killer Concentrate

We’ve got another systematic weed killer here. The Image Brush & Vine Killer Concentrate gets into the systems of the plant and kills it to the roots. As a result, your weeds can’t grow from the roots.

This one too is packed with standard features. Like it kills blackberries. And it doesn’t stop it’s murdering spree only at blackberries. It kills a number of other weeds with accuracy. Moreover, with one package you can clear up 4000 sq. feet of area. All these features bring this herbicide to this list.

However, due to a low price-quantity ratio, it fails to be at the top. Overall, this one’s absolutely amazing if you’ve got a medium-sized yard.

9. Crossbow Herbicide

As our last entry here, we’ve got another chemical herbicide. This one also uses triclopyr. So, it’s a contact-based weed killer. However, it’s not harmful to grasses and it’s somewhat selective.

So, what else does the Crossbow Herbicide offer us? Well, it kills a number of weeds along with blackberries. And most importantly, it goes rainproof within 2 hours.

So, you won’t have to keep a keen eye on the weather app while holding the herbicide at hand. Now, let’s look at the pros and cons-

Best Herbicide for Blackberries – Buying Guide

That was a lot. We’ve gone through 9 different herbicides. And all of them can kill blackberry weeds. But this makes the whole thing confusing. So, we’re here to make things easier.

While choosing an herbicide go alongside these features and you’ll find yourself the perfect match. So, let’s start-

Organic or Chemical?

Vinegar based herbicides are the only organic solutions in this case. However, while choosing chemical ones try to spot two ingredients. We call these Glyphosate and Triclopyr.

Now, the organic herbicide concept might sound better at this point. But if the infestation goes radical, then you must switch over to any of those chemicals.

Pre-emergent or Post-emergent?

This is basically the prevention and solution debate. The pre-emergent one will keep blackberries away from your garden. And the post-emergent one will kill the weeds once they arrive in your garden.

The first one works by hindering germination. The latter one works by killing sprouts.

Both are effective and easy to use. But the final call is yours.

Contact or Systematic?

The contact weed killers start working on contact. And even with this efficiency, it isn’t the top choice for everyone. It’s because this type of herbicide kills only the part above the soil. And if things go south, you’ll see plants growing from the roots again.

Systematic herbicides work slow but are extremely accurate. These are the snipers of herbicides. So, how do they work?

Well, the tree foliage absorbs the herbicide. And this assassin here uses the plant’s nutritional system to start attacking. It prevents the plant to make food from sunlight and water. So, within a few weeks, the plant dies.

The rule of thumb here is to use the contact herbicide annually and the systematic one perennially. However, you’ll find some herbicides have both of the worlds. So, choose accordingly.

Selective or Non-selective?

Here we have a mix of both types. Selective types are basically tailored towards one type of plant. These only kill one type and are pretty much harmless to others. On the other hand, non-selective weed killers are equally harmful to all plants.

Choosing Process

So, when should we choose which one? Well, let’s explore scenario by scenario.

If blackberry sprouts are everywhere, go for a non-selective weed killer. This post-emergent weed killer can be both systematic and contact.

If you see blackberry weeds growing amongst your garden flowers and veggies then things are different.  To protect the existing garden vegetables, apply a selective-contact based herbicide.

Now, if you have small sections in your garden and you don’t want to see weeds growing in your garden, go for a pre-emergent herbicide.

That’s all about choosing.

Parting Words

That was a long journey. We analyzed our top choices and then we went through a detailed buying guide. But we believe the effort was worth it. Because now you can choose your best herbicide for blackberries. Moreover, now you can be the local hero by giving your neighbors some expert advice.

So, move your back and order up that herbicide. Good luck. Happy gardening.
