Smackdown Herbicide is a fast acting contact herbicide and aids in the control of weeds through a process of membrane disruption. The foliar uptake of Smackdown Herbicide is rapid and plant desiccation can occur within 4 days of application. Application of Smackdown Herbicide should target small actively growing weeds.
