I still say Bob-O-rino is pulling your collective legs.

That would explain his low post count. Killing weeds with lasers sounds like something one would say with a bong in one hand--just MHO--

That idea belongs in a Cheech and Chong movie-rotfl.

antifreeze works great for weed control. Just don't tell the EPA your doing it.

Default Re: Crazy question about lasers for weed control

Some animals are attracted to antifreeze and will gulp it down. It will form crystals in their kidneys and do other nasty things. They will die a very PAINFUL death. Cats in particular are always dying from it, from lapping it up from puddles in parking lots and driveways.

If you use antifreeze for weed control, use only a necessary amount, and don't leave antifreeze puddles.

Unless your dealing with those pesky rats....i mean cats that keep digging in the trash.
However, I do believe a .22 bullet is cheaper than a bowl of antifreeze. It's quicker and less painful as well.

Default Re: Crazy question about lasers for weed control

LOL... It is POSSIBLE to do this, but not practical for a whole host of economic reasons.

I know there are farm tractor attachments that have IR cameras and can differentiate between weeds and the crop plants, and then there's a long row of electrically controled pesticide jets that will blast just the weed as it passes under the farm implement. This way it just blasts each weed with a small spurt, instead of saturating the entire field.

It's possible to make an image system that can differentiate between weeds and crops, and it's possible to get a laser to fire on those weeds, maybe an array of optical fibers to lens outputs. Kind of like the "laser printers" that instead of a single scanning laser, had a long bar of LED's instead. However, even a very powerful laser would not reliably kill weeds, because upper leaves would disperse the beam, so would smoke. And even if you could get the system to cut the weed off right at ground level, most weeds will grow back unless poisoned, or the entire root has been pulled out.

IMO in light (no pun) of the fact that bob has not posted again I think this is a troll thread. And thus Bob is just wasting our time.. just ask any gardener- if you dont get the roots you are wasting energy & time.
