Per the instructions to use the ortho dial spray, one 32 oz bottle should have done my yard. Instead after 2 bottles it only did half my yard. When I talked to customer service I was told it siphons quickly so I basically have to run instead of walk around my yard.

Was hoping Roundup's Weed & Grass Killer Concentrate Plus would eradicate the unwanted Bermuda grass in my yard. It did not. But it did work on other weeds.

I used this product to keep the weed down. I have very little weeds.

A big red label on the front of the 32oz. bottle and the instructions say "makes up to 10 gallons". Instructions for mixing, again on the front of the bottle and in the pull open instructions say to add 6 fl oz to one gallon of water. 10 gallons is possible only if you find the one line in all the instructions about to treating "easy to kill weeds such as seedlings". Then you can use 3 fl oz per gallon.

So when I poured the contents into the sprayer, it was gloppy and looked like it had a stringy substance. I thought maybe it would dissolve once I added the water. The first 3 or 4 batches were okay. I cleaned out the sprayer and 2 weeks later I pulled it out to finish/reapply. The first batch was okay but the second batch was gloppy again and this time clogged the sprayer. I don't know what's in the mixture to make it gloppy and stringy. First batch did kill the weeds! [This review was collected as part of a promotion.]

The directions state to use 6 fluid ounces to make one gallon yet the claim is that the 32 oz bottle will make up to 10 gallons. This math does not seem to add up. I have just sprayed some of my weeded areas and am still waiting to see the results. I was disappointed that I will not be getting more out of the concentrated bottle. What do you recommend? Using 3 ounces for a gallon or the 6 stated on the directions?

Let me know where to find the directions to make the 10 gallons of mix out of the 32 oz. can of concentrate,you know the red sticker on the neck of the can ? According to the directions on the label, the mix is 6 oz. of concentrate to each gallon of water. So each 32 oz. can could only be mixed with a maximum of 5.3333 gallons of water !! To mix it with 10 gallons would be diluting it by 50%. What's up with that ?!! I have used weed and grass killers since I was 10 years old. That's when my father allowed me to use POISONS around landscapes, in the fields, and gardens. I think it's fair to say,"I've been around." Roundup has competitors that have the same effects and abilities at a much cheaper price. I am using it only because it was given to me.

Maybe I was using this incorrectly but this didn’t kill off the weeds as I had hoped it would.

[This review was collected as part of a promotion.] Every year we deal with unwanted weeds with all of our landscaping. Rock and mulch throughout the yard looking gorgeous but moles somehow weasel their way under the mulch to pop holes into the weed barrier allowing the weeds to grow through our mulch. Every year we have to spray for weeds and nothing really works as it states. Roundup Weed & Grass killer was picked this year. We followed as directed, spraying weeds only since we didn't have any grass that needed gone. This killer took longer to "dry" them out, About 4/5 days before we noticed they was dying. The killer didn't shrink or make those pesky weeds disappear but only changing their color by killing them. I had to go around pulling the dead weeds by hand. I will say since we sprayed Roundup Weed & Grass Killer we haven't seen a mole lurking around or under our landscaping again. Would i use again, probably not because this killer didn't completely destroy the weed itself as i had to put some elbow grease into the process of pulling them out of the ground after they died. I might also add that it took quite a bit of spray to get the desired results we was looking for. Spray should be stronger/more concentrated if that's possible. Not one of my favorite weed killers but did kill them over a few days.

The media could not be loaded.  Did not come with measuring cup like add said!!
