To evaluate the response of the new ‘imi’ tolerant varieties, to novel herbicide strategies involving Group B and C herbicide products.
PBA Bendoc, PBA Amberley and PBA Samira showed similar relative tolerance to GpC in terms of crop damage, but slightly higher biomass reduction in PBA Bendoc, could indicate greater sensitivity. PBA Bendoc showed excellent tolerance to ‘imazamox & imazapyr’, even with GpC applied PSPE. Results also highlighted the base level tolerance that many conventional faba bean varieties have against imidazolinone products with PBA Amberley and PBA Samira showing almost no damage with the PSPE application of ‘imazamox & imazapyr’.

Two products were used ‘imazamox & imazapyr’ (Group B) and ‘GpC’ (Group C). They were applied at either individually, in sequence or combined at two application timings ‘Post Sowing, Pre-emergent’ (PSPE) and 4 Node crop growth stage (4N). N |

They were applied at either individually, in sequence or combined at two application timings ‘Post Sowing, Pre-emergent’ (PSPE) and 4 Node crop growth stage (4N). Note: The combination treatment was applied at half rates due to a mixing calculation error. |
