VASCM: Organic Herbicides vs Roundup

[Nick Pisano]

We run a Clemens Radius Plus and it works great. It has a blade that
undercuts the roots of the weeds then a vertical filler that follows. It
can be used on hillsides, sensor arm is very sensitive so it can be used in
young vineyards. Front or rear mount. Works great!
