I would agree that the products I have used don't seem to degrade either, b

e he hasn't said. Also in my experience the roundup and ground clear type
of products are effective for weeds in cracks, so something is wrong.
Look for pre emerge herbicides. Use of those plus the crop canopy
are a couple of the farmer's weapons against weeds. This might sound
odd but the main part of the weed could be outside of the crack. Some
have roots that extend a long ways. The farmers here will know the term
in an instant.
Weed killers are a lot better than they were 30 years ago. Fields
were weedy toward the end of the growing season back then. Now they're
mostly clear even into early September.
The old Roman trick to prevent anything from growing was to salt the
land. However, that would be a pain in the ass and would probably do
more damage to the concrete.
As you are pouring straight triox (bad, bad idea) into these gaps /
cracks, it would seem you are not concerned about chemical
contamination, if that is true, go buy a gallon of diesel fuel and
pour it in the problem area. When I was a youngster, that is how we
solved the issue you are describing. It's cheap, easy and not really
great for the environment, but neither is what you are doing now.
It might take several treatments over a few weeks, but soon, you will
not have weeds in the treated area,

I live in a 90+ year old neighborhood and some sidewalks are in
worse shape than others and the city is slowly replacing those.
Those older sidewalks have random cracks here and there and I
will weed eat what I see springing up right down lever with the
sidewalk. I have a large plastic bottle that I put the mixed
Roundup in and then put a dishwashing detergent fliptop cap on
this bottle so I direct a small stream of the weed killer on the
whole crack. First time I did this I used one of those pump
garden sprayers not realizing there was drift that day and ended
up killing a lot of things that didn't need to be zapped.
Anyway, this treatment I do lasts until the next Spring.

Head off to Home Depot and Lowe's and buy a bottle of Roundup
that you will mix with water.
Just last week I treated a spot that was asphalt with a patch of
weeds. It's free of whatever it was now. If weeds decide to
try it again in that spot it will be next year before they reappear.

Keep using the weed killer every time weeds grow back.

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.

Actually one of the advantages of Roundup is that it has no persistence. Yo
u can spray it on an area to kill everything and plant seeds immediately. U

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.
