Group 2 herbicide tolerant pulse crops
• Grain yields of all species (lentil, field pea, faba bean and chickpea) at this site were very low and generally less than 0.5 t/ha. Seasonal conditions were very dry during autumn and winter before favourable spring growing conditions (rainfall and relatively cool maximum temperature during September and October) provided for some yield recovery.
• Triasulfuron (e.g. Logran, sulfonylurea herbicide Group 2) residues and the in-crop application of Intercept® (imazamox + imazapyr, an imidazoline herbicide Group 2) resulted in total crop failure in the conventional (non-herbicide tolerant) varieties of all four species.
• The presence of Intercept® residue did not affect the grain yield of the conventional field pea variety (PBA Wharton) or conventional faba bean variety (PBA Samira). However, Intercept® residues completely killed the conventional lentil variety PBA Bolt and reduced yield by two-thirds in the conventional chickpea variety CBA Captain.
• PBA Highland XTA (imidazolinone tolerant) showed good tolerance to Group 2 herbicide treatments, including where triasulfuron residues were simulated.
• Triasulfuron residues suppressed the yield of the imidazolinone tolerant faba bean (PBA Bendoc), field pea (GIA2005P) and chickpea (D16218). However, yield was not affected by the post-emergent application of Intercept® and Broadstrike®.
