BioAdvancedWeed & Grass Killer Spray, 24 Ounce

Not very strong ,doesn't kill some weeds and others even double the recommended dose still over 48hrs before you notice.Will not purchase again.

I've been landscaper for 25yrs and this is great stuff ..you must spray this when the sun is out as weed killer is controlled by the heat..spray on hot days and weeds are dust..5stars and will keep purchasing at a great price..thanks

This used to be branded as "Bayer". When it was Bayer it was a thick white consistency before mixed with water. You could start seeing results in a day and no weeds would come back for at least 6 months. When I ran out and needed more I couldn't find it anywhere. When I found that it was rebranded as "Bio advance" I was excited I actually found it. That excitement quickly wore off as soon as I opened the bottle. This is now a thin watery blue liquid instead of they thick white liquid it was before. When I applied it, it took 4-5 days before the weeds started to look even a little wilted. It did eventually kill the majority of the weeds, but it only lasted a couple of weeks before they started coming back. I will be looking for a different weed killer next season.

Sprays much better than other brands but I'm not having much luck with it killing anything. It turns the weeds slightly brown but they are very much still alive. Trying a second application. I've tried it on several types of weeds none have died. It's been about 4 days.

Has not been effective. Weeds are still standing proud.

I applied this product and was initially disappointed because I didn't see results in the first few days as I do with similar products. Within 7 days, everything this stuff touched was dead as can be. It is a great product and all I will use moving forward. There is no "worked here, but not there". You spray this on something green and it will be dead in 7 days. Love this product!!!!!!!'

Hubby used it on the short and tall weeds. It killed them dead. Will monitor to see if they grow back.

Takes about 72 hours to start seeing results. At first I didn't think it worked on my weeds and grass. Now everything it touched is dead. Worked great and killed everything. Will definitely buy again when I need more.
