Potato Haulm Killing with electroweeder?

New development for potato haulm/vine killing with an electroweeder instead of herbicides.
It has the following specs:

8 m application width
4 km/h application speed
3 HA / hour
2 liters diesel consumption / HA
25 liters conductive liquid / HA

Very clever to first spray the potato vines with a salt solution to increase electrical conductivity, reducing the voltage requirements! Thanks for sharing this Marleen!
