Hi-Yield(32171) Killzall 365 (1 gal)

This stuff works! I used 6oz. per gallon as directed and it works great.I was beginning to wonder if I needed to go back over everything, but after a week or so everything was dead.In the driveway I could pull the weeds right out of the gravel. Meaning it did kill all the way down to the roots!It killed everything!! So I would not try it around trees or shrubs.I could have taken pictures of everywhere I used it because it worked everywhere!It also has a red tint to as you spray so it's easy to see what areas were done. The tint disappeared as it dried.I sprayed the whole driveway instead of trying to spot the weeds like my wife tries to do. Then a week later (for her) the weeds you couldn't see would pop up and she's doing it all over again.I will be buying again as one gallon goes a long way being a concentrated product.It was late in the yr when I used this product so I will not be able to tell how long it last, but I have plenty left to do it again in the spring.

It's been very effective in vegetation control.

I bought these to get rid of a very invasive and hard to remove weed called Knotweed. It was very effective when following proper directions. Extreme care recommended while handling it for dilution and applying it. Leaves of the weed dried off and stem turned brown/black within a week after application. No growth observe after that for a month. Will have to wait and see if the effect truly lasts for an year.This didn't work very well on Himalayan blackberry - it worked on some plants but not others. It's not really recommended for blackberry but just sharing my experience.

rm43 is expensive, this is much less and it looks and works the same as rm43 does. I use it to spray my driveway and sidewalks. We get very hard rain at times and as long as this has several hours to dry, the weeds are toast... very worth the money, esp compared to rm43.

Switching from 4 stars to 5. A few more wks and results are impressive. No sign of spreading to plants outside of sprayed area. I wouldn’t use this near streams or runoff areas but for our dirt driveway it’s working great!Previous review: It's taken 5 days to really see the beginning of results (pictured). It seems to be working so far. Interested to see if results last. Note this product is toxic & should never be used near water or runoff areas.

It kills the weeds you see, but you will have to re apply a few times through spring. Jan, March and May in Nor cal.

Watch it kills every thing !

I grabbed a gallon of Hi-Yield Killzall 365 and it was a game-changer! One moment, my yard looked like a botanical garden for weeds, and the next, it was a desert. 🌵In just days, I felt like I was living in a weed-free oasis—my house and car were finally visible again! It's like the weeds got the memo and decided to scram! If you ever feel outnumbered by greenery, this is your secret weapon. Five stars for bringing me back from the brink of becoming a plant hoarder! 🌿🚫✨
