gasoline kills vegatation fast


But the effects do not last as long as a weed killer such as
Roundup. For years I used gasoline for those cracks in my
sidewalk with the weeds reappearing in about 4 months. One
treatment with a weed killer last until the next year.
Roundup only kills what is growing at the time. Within about 2 weeks
it has deteriorated to 50% , and there is virtually no carryover after
2 months. With regular roundup you can reseed gras within 10 days.

More confusion. With regular roundup, ie glyphosate, you can re-seed in just 3 days. And if you're using one of the long term roundup products, then it's blocking effect lasts many months.
