Farming robot kills 100k weeds per hour with lasers

Presumably the laser wouldn't be setting the whole plant up in smoke. Couldn't it target the base and let it fall?

My understanding of poison ivy is that no part of the plant is nontoxic. Burning just the base would minimize the toxic cloud, but not eliminate it.

I really don't think that burning a line an inch long and 1/16th of an inch thick at the bottom of a stem is going to release any significant amount of toxic cloud. A tiny bit if you're right there next to it, sure, but it would be dissipated within a few minutes.
