I have been having great success using “Liquid Bleach” as a replacement for "RoundUp, since RoundUp has been banned for residential use in Ontario.
The good thing about using liquid bleach, is that it is far less expensive; you use it undeluted; and it works much faster than RoundUp.
I just pour it into a rinsed out spray bottle and spray it on anything I want to get rid of.
Spray when the vegitation is dry. You might need several applications if the plant life is not dry enough, such as soon after a rain. Be carefull where you spray; it seems to kill just about anything it gets sprayed on.
Please be careful pouring the stuff, so that you don’t get it on your hands or clothes.
It will discolour any clothes, and might irratate your skin. Also protect your eyes.
Liquid bleach is commonly used as a cleaning agent and disinfectant, so most people have it in their home, and are used to it’s characteristics.
