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.
Aims and Objective:
(i) Project aim(s): To enable growers to select herbicides that are not damaging to newly planted blackcurrants.
(ii) Project objective(s):
o To investigate the efficacy & phytotoxicity of various herbicides alone and in combination, applied to cuttings within 48 hours of planting.
o To investigate the potential for reduced rate mixtures to improve weed control and reduce the risk associated with each herbicide.
o To investigate the ‘sub lethal; effects – i.e. growth suppression
