Rated 4 out of 5 by from Good product / bad design I bought three bottles to use with my hose sprayer. There doesn't seem to be enough threads to keep the bottle firmly attached to the hose dispenser. Two of the bottles "fell off" and partially spilled before I could react. It kills the weeds, but be careful with the screw-on bottles. Might be nice to have an extra turn to keep the bottle secure.

Rated 5 out of 5 by from Great product! We don't have too many areas with crabgrass anymore now after our lawn treatments but we applied this in the spring to our trouble areas last year and it was great - even had enough for some spot treatments this spring as well!

Rated 5 out of 5 by from Great product! I needed a second does of crabgrass prevention during the late summer months, as that’s what should be done, and saw this product...gave it a try and the crabgrass was stopped in it’s track! Easy to use at the same time as well! [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Good chemicals, but very poor sprayer Dear gardeners, be cautious of this product. Granted, the chemical is fine and I have used in the past with excellent results. This year, the sprayer is worse than bad! The spray pattern is a cone and the droplets fly far away (some about 7 feet) from the central area, which poses a risk for nearby shrubs and makes it difficult to spray uniformly. The second bottle had a flattened cone, and that means the manufacturing quality control is poor. Prior year's bottles had a farther reach and one could control the swath with water pressure - not this one. Lastly, one cannot pour out the small amount left over at the bottom to use in another bottle because the cap and handle cannot be screwed off. I am disappointed and will not buy it again.

Rated 3 out of 5 by from Does it work? Hard to tell. I used this product as directed. I have a pump sprayer with gallon measurement on the side. So I was definitely mixing this product with the appropriate quantities of product and water (I even put a bit more of the product in the mix than directed). There is no visible result after a week to the clover that is overtaking my yard. I did notice that it would just bead right off the clover leaves as I sprayed them, leaving very little sitting on the foliage of the plants. So it’s hard to say if this product would have worked or not. Should something else be added that can help stick the product to the clover? Not mentioned in directions.

Rated 1 out of 5 by from Product works but the bottle is SO BADLY DESIGNED! Although the product works fine, Ortho has GOT to change the design of the hose end sprayer. It is an incredibly wasteful single-use product. You cannot get the sprayer off the bottle to combine the last bit with another bottle - so, it cannot be recycled. The handle is screwed TO the bottle with metal screws and the internals cannot be separated from the bottle without destroying it. So, hundreds of thousands of these things filling up our landfills! Do the environment and your CUSTOMERS a favor and use the design used by almost all other hose end manufacturers - it simply unscrews the sprayer from the bottle! The product itself works fine, so buy the concentrate.

Rated 1 out of 5 by from Just wanted to say Goodbye Weed B Gon! Goodbye Weed B Gon! I started using you 18 years ago when I bought my first home. You used to work so good. 2 treatments a year made my yard look great, not perfect but great. The past 5 years or so I noticed you not working so well. I'd buy another bottle and it would work better. It's to the point where I mix you twice as strong as you recommend (2 oz per gallon...I use 4 oz per gallon) and you're still not killing weeds and no effect on crabgrass. I guess the saying, "all good things must come to an end" applies to you also!

Rated 5 out of 5 by from Very good quality product I tried this product last year as I had crab grass in the lawn. This product worked well as intended and I see the results - it stopped new crabgrass. I think it is very effective and quality product from Scotts.

Rated 1 out of 5 by from Killed nothing. Two applications. Total waste of money. I wish I had kept the receipt. Zero rating.
Date published: 2019-06-08
Rated 5 out of 5 by from Better than expected! Absolutely works as advertised. Crabgrass simply disappears. I would have preferred an application via my Scott's spreader but can't ague with success. The application process wasn't difficult. It probably took the same amount of time a spreader application. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Kills Dandelions Blanket sprayed our front and backyard in the evening, woke up the next morning and every single dandelion was already dead and shriveled up. My husband mowed over them and now our lawn looks great. The only con is that the sprayer is messy.

Rated 1 out of 5 by from My Lawn Is Destroyed I used this product as directed and my lawn is TOTALLY DESTROYED. My gardener use to pick the crabgrass with his hands.

Rated 5 out of 5 by from Works Great! I use Weed B Gone and it kills weeds instantly. The product works great. Highly recommended. Easy to use and very effective. Kills the weeds and they don’t come back. Product gets deep to the root. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Bottle was broken or something I bought this bottle, hooked it up and realized in the middle of it that it wasn't spraying any product. I thought I was not watering enough but after a full lawn watering almost nothing has come out. My water pressure is great and I set it to "on". The bottle container seemed to be getting filled with water than spraying out. First time user of a house attachment and disappointed with the experience.

Rated 4 out of 5 by from Happy with it easy to use. Kill the crabgrass while while leaving the lawn alone. You can maintain your lawn without that much effort.Thats a bonus for me. And it last a long time. Would recommend using this product if the crabgrass is taking over. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from Doesn't work on my crabgrass or weeds I don't know what is in this stuff but it doesn't do a thing for killing crabgrass or weeds in my lawn. I sprayed 5 days ago and they look more healthy than they did before I sprayed!
Date published: 2019-04-01
Rated 5 out of 5 by from Excellent product I used this last summer on my lawn and it did an amazing job killing the crabgrass and also the dandelions. I will surely be using this product again this summer. It is very easy to mix and apply to my lawn.. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Easy to use When I used this last summer its worked great! In just a couple hours on a sunny day the weeds were dying! Loved it! I would use it again. I have a gravel driveway and the weeds just love to take root there. [This review was collected as part of a promotion.]

can I use concentrate in a 32 oz. spray application bottle, if so what amount?

Asked by: Rich 1007
Rich, the Ortho Weed B Gon Plus Crabgrass Control Concentrate can not be used in the 32 oz Ready- To-Spray bottles. However, it can be used in a tank sprayer or with other hose end applicators.
