    Trying to permanently kill weeds and anything else growing in certain areas of my alley and sidewalks. Would it cause any toxic hazards if I mix salt and roundup to apply all at once? thanks in advance

    Not a toxic hazard, but Roundup is for short term killing. You can use roundup (without salt) and plant few days later.

    For longer term crack etc killing, you would be better to use vegetation killer designed for that.

    Regular Roundup takes two weeks for a full kill, root and all. No reason to add salt, however using salt alone will kill everything but a longer while for the salt to leach out of the soil. Roundup does not kill seeds. Roundup comes in all kinds of Glyphosate concentrate. The higher the concentrate percentage, the higher cost. Glyphosate is now available in generic formulas. Most herbicides of other brands will be glyphosate and at any level of concentrate.

    Roundup Quick Pro: It's the Diquat that make it a 24 hour kill
    *Glyphosate, N-(phosphonomethyl)glycine, in the form of its ammonium salt.......... 73.3% .
    Diquat dibromide [6,7-dihydrodipyrido (1,2-a:2’,1’-c) pyrazinediium dibromide] ...... 2.9%
    OTHER INGREDIENTS: ............................................................................................... 23.8%

    The only two members of my family that liked using Roundup are now dead. The rest of us are okay though.

    You are doing right by destroying everything that is somehow related to weed in your alley, nowadays teenagers can try to smoke it or even sell it to someone, so it would be better to destroy it at once. I have been addicted so I know that it never ends happily and you always have to pay for what you have done. I managed to get rid of it, but I am sure that there still are people who smoke weed and even don't understand what danger they are. I managed to get rid of it only by purchasing kratom capsules, and thus using it I could re-establish my life. Addressing all people who are smoking weed and think that it only relax, it also harms your health and mind.
