The Vogels Wick Weeder is a rope wick applicator that efficiently places herbicide on weeds. It saves money and improves performance by delivering the herbicide where it is needed and only there.
Wick Weeders are available in hand models, trail models, can be mounted onto ATV/UTVs or loaders, or custom mounted on pretty much any piece of equipment that suits your purpose.
