Broadleaf weed control in chickpea – Dalwallinu 2021 locations
Aims

To compare two chickpea varieties for their competitiveness against broadleaf weeds and evaluate efficacy of new and old herbicides and herbicide mixtures for broadleaf weed control in chickpea.

Key messages
  • Chickpea varieties - CBA Captain and Neelam showed similar competitiveness against broadleaf weeds. Competition of RR canola (mimicked wild radish) and broad leaf weeds with these varieties to maturity accumulated 4.2t/ha dry biomass and reduced chickpea seed yield by 35% compared to weed free plots.
  • Majority of the herbicides and herbicide mixtures registered 95-100% weed control efficiency against RR canola and broadleaf weeds and yielded on par with weed free plots. Application of flumetsulam 800 at 25g/ha at 4-5 node stage of chickpea reduced canola/weed biomass by 69% and increased chickpea seed yield by 25%.
  • Incorporated by sowing application (IBS) of herbicides/mixtures appeared safer than their post-seeding pre-emergent application (PSPE). IBS application of fomesafen, flumioxazin, terbuthylazine + isoxaflutole, and simazine + diuron + isoxaflutole had no significant negative effect on root nodules of CBA Captain.
