Herbicide

Marengo, a liquid pre-emergent herbicide, is now available in a convenient 18 fl.oz. container to accommodate users of all sizes. Launched in 2013, Marengo has become widely used due to its long-term residual control of both broadleaf and grassy weeds, plant safety and efficacy. It can be used under benches, on ground cloth, on gravel areas and on dirt floors in greenhouse structures.
