You are comparing nothing here. You forgot one whole leg of the comparison... i.e. the pesticide production footprint.

I was comparing it to the equipment used to carry the laser or pesticide. The application of pesticide itself is ~2-3 orders of magnitude larger the laser before you consider manufacturing or transportation.

The laser itself is a rounding error here, what matters is the other equipment involved.
