It goes by the name of “Rototiller Red”.
You might see this invasive species beast on the prowl for Eurasian Milfoil on Osoyoos Lake this month.
This rototiller, operated by the Okanagan Basin Water Board, is designed to remove milfoil by its roots from lake-bottom sediments. Although 100% removal is not achieved in one treatment, repeat annual applications can reduce milfoil density to a low level.
The tiller mechanism is lowered to the lake’s bottom (4.5 metres or less) by skilled operators who feather the rototiller blades along the bottom removing the milfoil by its roots.
The cost of rototilling is approximately $2,500 per hectare.
