Key Points:
- This Arable Update builds on Pulses No.25 by detailing 3 trials in the 2006/07 season to evaluate the effects of sowing rate and pest control on the yield of white lupins.
- Two European cultivars, Promore and Lublanc, were tested at Geraldine, Kairanga and Bulls.
- With no insects or diseases at Geraldine, yields were greatest at the higher sowing rates.
- There were low levels of anthracnose at Kairanga. Fungicides reduced disease incidence and gave a slight, but inconsistent, yield increase.
- Anthracnose was present at high levels at Bulls and severely impacted on yield. Fungicides slightly reduced disease incidence and severity and increased yield.
- Anthracnose is a seed-borne disease. None of the fungicides sprayed in these trials were registered for its control.
