Roundup Concentrate Plus Weed & Grass Killer, 16 oz.

I used on weeds in the cracks of my driveway and patio. Took a few days to see results, but boy did I ever. I has now been 4 weeks and weeds have browned and died. A little goes a long way. I suspect if I used this at the end of spring I will only have to do one treatment per year which will be awesome.

it has different ingredients than regular round up weed killer: so if you add the recommened amount to "round up III weed killer= you get a super product that can kill "johnson grass" and established poison ivy and other "impossible" invasive species

I put 2 gallons of water to 8 ounces that was wrong suppose to be 1 gallon water to 8 ounces but it still worked It worked great weeds grass everything Dead good

This killed the grass and weeds sprayed within a few days. Had to respray one area, so probably some user error. Love this concentrated weed killer to last me longer.

Works great & clears everything to the dirt. I use 2-gals once a year for my edging & pavement nooks with an if needed 2nd spot treatment on occasional new & latecomers. This bottle needs 2 more ounces for a full 3gal mix-up, for 6oz per gallon people. FYI, this Red Cap is the liquid Semi-concentrate, the Purple cap is the syrup Ultra-concentrate.

The 32 oz. container states " makes up to 10 gallons". The directions state mix 6 oz. per gallon of water. This only gives 5 1/3 gallons when mixed as directed. When mixed as directed how can I get 10 gallons? [This review was collected as part of a promotion.]

Terrible!! i used it as directed and the foxtail grass kept growing for almost 2 weeks!!!! therefore the plants actually grew foxtails and has made hours and hours of extra work for me and i am angry about it because i have a bad back!!! PREVIOUSLY, i used similar but different brand last time and it worked like a charm, will never buy this again!!

sprayed it on yesterday afternoon, got up this morning and nothing changed. we'll see if stuff starts to die in a few days but it says results in 12 hours and we got no results.

directions recommended 3oz per gallon. I used 4 oz. per gallon .this is 5th day since sprayed and the weeds and grass look like they have been watered and cared for

When following directions to remove cap put pressure on bottle, cap doesn't come off, but liquid squirts out from under useless safety cap. Getting all overt my hands. They do not have bottled sealed under cap. Worst design ever. Need refund.
