Blackcurrants: refining herbicide screen for use in recently planted cuttings

Summary: Project SF154 identified some potentially useful herbicides for application to freshly planted cuttings.  Some of these single treatments caused damage at high rates and some allowed certain weed species to establish as a result of an incomplete spectrum of activity.  This project is designed to investigate the potential to broaden the range of weed species controlled while reducing the risk of phytotoxicity to the cuttings.
