Broadleaf weed control in chickpea at Binnu 2021 locations
Aims

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

Key messages
  • Majority of the pre-emergent herbicides and herbicide mixtures registered 88-100% weed control efficiency against wild radish. Post-emergent application of flumetsulam 800 at 25g/ha alone at 4-5 node stage of chickpea reduced wild radish number by 86%.
  • Interaction of post-emergent flumetsuam with pre-emergent herbicides/mixtures for wild radish control was positive, whereas for chickpea seed yield it was negative in majority of the cases.
  • Pre-emergent application of flumioxzin alone and in mixture with other herbicides, BADPI21 and simazine + diuron + isoxaflutole caused 21 to 41% loss in chickpea seed yield.
  • Pre-emergent application of fomesafen, flumioxazin, terbuthylazine + isoxaflutole, and simazine + diuron + isoxaflutole had no significant negative effect on root nodules of CBA Captain.
