Hi-Yield (33693) Super Concentrate Killzall Weed & Grass Killer (1 gal)

Very satisfied with the spray effectiveness. It took about 5 days to see good results. The sprayed area kept looking more brown indicating that it keeps on working. I sprayed this with a garden sprayer and my helper used an electric spray wand. I mixed it as 3 Tbl spoons per gallon to ensure it was non-selective. It was very easy to mix as hi-yield includes surfactant pre-mixed. I started with water and then added the herbicide. It was fast spraying. I had also tried concentrated vinegar at first, but realized I needed something that also got to roots and nodules. The kill speed using herbicide is as expected. It has been several. I recommend wearing gloves when handling this concentrate as well as during spraying. This is quality herbicide concentrate. It has been weeks after the spray and there is no fresh growth in the sprayed areas. I still have plenty herbicide concentrate for the next season. This was a good purchase.

Great all around grass and weed killer. Use it to treat the perimeter of my fence and it works in a day or two.

I bought this to kill stubborn weeds in my gravel driveway after trying all season with other products. I didn't diluted it as instructed. I had it stronger and mixed with vinegar instead of water. That killed my weeds!

works well -- I mix about 1/4 oz heavy to the gal. and within 5 days I have no green grass or weeds. I have use this product the last two years and will be ordering more soon. One caution - don't spray if wind is more than a very light breeze

Used it to spray my driveway and it took care of all the weeds and grass in one shot, very effective. Doesn’t show the instant results like RoundUp, but who cares. It works great and is more cost effective.
