40 years or so ago Roundup was touted as being OK for organic growers and I have used it quite a bit - especially against rampant weeds on small acreage. With the recent findings and reading on here I have cut back and been looking for alternatives when I remembered the old blow torch flame thrower weeder I used 20 odd years ago. I found it buried in the junk in the back of the garage and pulled it out. I have given it a complete overhaul - new seals and washers lubricated the tap threads so they move easy and about to pressure test it before firing it up. Those that don't know the beast it is a sturdy tube about 3' long and 2" in diameter with a pump in on end to pressurize the kerosene fuel inside. The business end is separated by a control tap from the main body and is a burner tube 2" in diameter and about 1' long. The thing works like the old pump action blow torches and throws an intense flame about 2" long out the end. I used to use it to weed a gravel drive way but this will be just the thing to knock the Cobblers pegs on the head as it destroys seeds in a flash (pun intended) - No problem with spray drift and a quick pass wilts weeds and they die off - great for sterilizing soil if you wish it prevent competing seed germination as well.
