To investigate the tolerance of a newly released faba bean variety PBA Bendoc to residual (simulated) and in-crop application of various Group B herbicides in comparison with the commercial variety PBA Samira. 

Key messages
  • Group B herbicide application timing significantly influenced herbicide damage, biomass and grain yield loss of faba bean varieties. Herbicide damage and subsequent yield losses were more severe in the conventional variety PBA Samira than in the group B tolerant variety PBA Bendoc, and generally increased with delaying herbicide application timing from PSPE to 4 node, 8 node and flowering stages. PBA Samira incurred significant yield loss from all the herbicide treatments except PSPE and in crop application of ‘Imi2’, and application of ‘Imi1’ up to 8 node stages. In contrast, PBA Bendoc showed improved tolerance and did not have significant yield loss from the herbicide treatments except in-crop application of ‘SU1’ and ‘SU2’ at 8 node and flowering stages. The results should be treated with caution due to the confounding effect of dry seasonal conditions and repeated frost events.
