Can Farmers Zap Weeds with Lasers? By Bob Farmer, Dairy Farmer

At this time of the year, I spend too much time dealing with weeds, mainly on hillsides for fire prevention on my farm. The steep hillside makes use of my tractor impossible and even use of a brush cutter is limited. The weeds like to grow thick in the most inconvenient places. So, it is up to me to climb the slopes with my machete, my latest being from Brazil by Tramontina: https://www.ebay.com.au/itm/123974920215?_skw=26+inch+machete.

But it is hard work, especially for an old farmer.

Thus, I was fascinated to read about the use of lasers in killing weeds. This is part of a machine, but I wonder if some sort offhand-held laser could be got to zap the weeds on hill slopes? I could then become the Jedi farmer! But I suppose any such device would be classified as a weapon, and hence banned, at least here in woke Victoria.
