Herbicide tolerance of lupin varieties - Wongan Hills locations
Aims

To identify herbicide sensitivities of new lupin varieties with the view to reduce their yield losses due to herbicide damage. Mandelup was included as a standard variety for comparison in the trial.

Blue lupins are problematic in narrow leave lupin production, especially in the Northern Agriculture Region of WA Wheatbelt and no herbicide is registered for their control in this crop. There were earlier reports that blue lupins could be controlled/suppressed with triclopyr (e.g. Garlon®) safely applied at pod setting on main stem of narrow leave lupins (Quinlan and Fleay, 2016). Two timing of application of Garlon® at 30 mL/ha were included in the trial to determine their safety on new narrow leafed lupin varieties.

Key messages

All the lupin varieties tolerated the registered pre and post-emergent herbicides at the label rates and timings with good safety margin.

A new herbicide Ultro® 900 WG at 2.3 kg/ha applied before seeding was tolerated by all the lupin varieties.

For blue lupin control/suppression, Garlon® 600 (triclopyr) at 30 mL/ha applied at 8-leaf stage of narrow leafed lupins was tolerated well by all the varieties, whereas its application at pod setting on main stem of narrow leafed lupins caused statistically significant yield loss across all the lupin varieties (18-24%). Triclopyr use on narrow leafed lupins is not registered.

Note: Always follow label recommendations. The Department Primary Industries and Regional Development, does not endorse the use of herbicides above the registered rate or off-label use of herbicides or off-label tank mixes. Crop tolerance and yield responses to herbicides are strongly influenced by seasonal conditions.
