Benefits of 28% UAN
- To ensure maximum performance of Viper ADV, BASF 28% UAN increases spray droplet retention and herbicide absorption by weed foliage.
- BASF 28% UAN has been filtered to remove any particulates that may impede sprayer performance. This eliminates the risk of time-consuming clogs and helps you apply an even and controlled spray.
- Its unique properties allow the two principle chemicals in Viper to work together to effectively control grasses and broadleaf weeds.
