Broadleaf weed control in CBA Captain chickpea –Mingenew 2021 locations
Aims

To compare efficacy of new and old herbicides and herbicide mixtures for broadleaf weed control in chickpea.

Key messages
  • RR canola which was sown into plots to mimic wild radish produced 4.1 t/ha of biomass by maturity and reduced the seed yield of CBA Captain chickpea by 47% compared to weed free plots.
  • Majority of the herbicides and herbicide mixtures registered 95-100% weed control efficiency against RR canola and produced similar seed yields to weed free plots. Application of flumetsulam 800 at 25g/ha at 4-5 node stage of chickpea reduced canola biomass by 99% and increased chickpea seed yield by 74%.
  • Post-seeding pre-emergent application of a three-way mix of Simazine 900 835g + diuron 900 333g + isoxaflutole 750 100g/ha and post-emergent application of REDPI21 at 4-5 node stage caused significant seed yield loss of chickpea.
  • Pre-emergent application of fomesafen, flumioxazin, terbuthylazine + isoxaflutole, and simazine + diuron + isoxaflutole had no significant negative effect on root nodules of CBA Captain.
