Here you go, it qualifies for prime too

Kill the weeds with fire! I use a propane weed burner, there's no chemicals and it works pretty well. Of course you have to keep up with it since the weeds will grow back, but that's only an excuse to use your new flame thrower! I have this one, it's somewhat propane hungry, and can be finicky about staying lit but it gets the job done without too much fuss.

I have a personal version of this, a handheld red dragon flame thrower for weeding, hook to a propane tank, light it, have way too much fun weeding until you realize weeding next to a PVC pipe is making the pipe start to melt... Also, I wouldn't use it in a grass yard as it will kill all the grass around the weed too. But in an Arizona rock yard, it works great. Can't kill rocks.

In all seriousness, it works really well. My yard is rock, anything growing in it is most likely a weed, run the flame over it for a couple seconds and the weed looks normal, but dies inside. 3-4 days later the weed completely brown and dried out to the point where the next time the wind blows it disintegrates. Or you can walk over it and it pulverizes from the impact.

It is not harmful to the soil like sprays can be, and it doesn't prevent new weeds from sprouting, so if you want to use it to control weeds you have to do it daily to catch new growth before it can germinate for a while. But its the most stupid-fun way to weed my yard I've ever had. I just don't do weeds right up against the house, cause I like my house, and don't want to risk it.

I'd imagine for farmers, this kind of thing could be very useful, you're killing all the weeds that grew while you prepped the field, before you planted, which could provide nutrients back to the soil from decomposing plant growth and your crop doesn't have to compete with the larger weeds to grow and you don't have to spend time pulling the weeds on a large field before the crop is planted.

Roundup or a weed torch will make quick work of them.

If you don't like Roundup (I try to avoid it, but will use it if necessary) you can try boiling water and/or vinegar. Neither is as effective or quick as Roundup, but both work.

In the end, no matter how you kill the weeds, they will come back quickly unless you fill the cracks and seal the blacktop.

Here's ours. Keep an extra person with a hose nearby, esp. since it's near burnables like that fence and there is likely some dried up detritus nestled with the rocks that could burn. You don't have to actually set fire to anything--the passing of the torch over the weeds causes cellular damage and they wilt and die. It is, however, very torch-like with a scary hissing sound and flame. But still, don't burn your house down.

I just got one of these for weeding between pavers. Seems to work well in gravel/paved areas. Spots with nearby plantings or areas of flammable brush are not good.

There's also a bit of a learning curve on which weeds need just a quick pass and which ones (grasses) need a longer pause. And the obvious risk of fire danger, though vinegar has its own health risks (you'll want to wear face/eye protection).

Same but I use this for the Smokey Joe, and this for the big fires.
