Bonide Captain Jack's Deadweed Brew, 128 oz Concentrate for All Types of Weeds and Grasses, for Organic Home Gardening

Seems to be safe around everything we have used it around. And results show in about 45 minutes or less and it legitimately looks like it is dead.Great stuff!

I applied the concentrated formula from a backpack sprayer to a variety of weeds on a pathway. Worked universally well on everything that I treated. It does have a pungent odor that persists for up to 48 hours. Be careful of overspray because this stuff really works and seems to kill anything it touches.

The product is great. I have nothing to save but good things about the product's capability to work and destroy plants - even knock poison ivy back a little bit. However, I made the unfortunate mistake of not reading or paying attention to the fluid ounces for this listing. The price is absolutely not worth the volume received since I can get double the volume for about $5 more from other main home improvement stores. Just pay attention to the numbers before you buy and do some quick math!

Love this stuff. Works even on nasty plants like bindweed, without the concern of runoff and toxicity like Roundup. A few tips: Mix at the 9% solution rate, cover all leaves well with solution, repeat treatments after a couple of weeks as needed, and consider adding a "sticker" to the mix to make it cling just a bit longer and not drip.

This stuff works pretty well. It killed most of the weeds I used it on, turning them brown and wilted within 15 minutes on a warm day. I’m not sure why people still use Round Up when there is such an effective organic weed killer available. One thing I’d recommend is to wear some kind of mask while you spray it. I sprayed a bunch of it and wind blew the fumes towards me. It may be organic but it still smells bad/burned my nose a little.

I used this on 2 weeds that had niried their roots into our buildings roof. We tried pulling these 2 weeks put..didn't budge. So I ordered and tried this product. Mixed it at the highest ratio. Within a couple hours after saturating all the leaves,stem and what roots I could see...the whole weed turned brown. A week later, all that remained was a brown stick. Now removed. Great Product.

This is expensive weed killer. When mixed as per instructions & sprayed, it will kill some of the weeds & not others. Does not make a difference what type of weed. It works fast on those you sprayed but others don’t even look like they were sprayed. This happens too many times for it to be a missed weed. It is too expensive to do half the job when I make sure that it was well mixed.

We really wanted to get away from toxic weedkillers like RoundUp, but have struggled to find something natural that really worked well. This stuff is by far the best we've ever used. I mixed it according to the directions for a 6% solution, sprayed the weeds in the morning, and they were dead and shriveled within a few hours.It does have a pretty strong smell, but I didn't find it too overpowering and it fades over time.
