People and pets may reenter the treated area after it has dried.

To protect the environment, do not allow pesticide to enter or run off into storm drains, drainage ditches, gutters, or surface water. Applying in calm weather when rain is not predicted for the next 24 hours will help ensure that wind or rain does not blow or wash pesticide off the treatment area. Rinsing application equipment over the treated area will help avoid run off to water bodies or drainage systems.

The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Application around a cistern or well may result in contamination of drinking water or groundwater.

Rated 5 out of 5 by from Kills most weeds quick! This stuff REALLY works on my Norman OK lawn. I sprayed it on a Monday and all leafy weeds started dying the next day! The other types of weeds are a bit more stubborn but I can tell they're in trouble too ha! I can apply it one more time in 21 days but may not need to. Follow Directions for best results. For Bermuda grass apply in temps of less than 85 degrees. Again read directions!

Rated 5 out of 5 by from Great Product This is the only thing that has worked for my lawn. I used Scott's while having a pretty thick and lush lawn with some complications and it destroyed my lawn as if I never cared for it. Weed B Gone was the only.thing that helped it on its path to restoration. I'll definitely use it again this year.

Rated 5 out of 5 by from Great product, very effective I’ve been using various forms of Weed-B-Gon for years with excellent results. I don’t understand for the life of me why others say it doesn’t work.

Rated 5 out of 5 by from Expiration date I have used it many times. It is a great product. However, I cannot find and expiration date on my old bottle of ORTHO Weed B Gone Weed Killer. I sprayed it on the back yard to eliminate a lot of weed there. It did not work. The weed is very green and healthy. I have had the bottle for maybe 3 years. I am looking everywhere for an expiration date and cannot find it. I think these type of products should have an expiration date. If any one knows where the expiration date is, please, let me know. We need to read the expiration date when we are purchasing these type of products. Otherwise, we could be purchasing an expired or soon to expire item. They are not cheap.

Rated 5 out of 5 by from Effective on so many lawn weeds. I have used the concentrate form of this product for several years. It is diluted and placed in my backpack sprayer. It is the first weed killer I spot apply on my acre lawn in March because it controls so many of the weeds in southwest Louisiana.

Rated 5 out of 5 by from Great product east to use I've used this for years and works great, especially considering how many types of weeds in one application.
