Blackspot management in field peas, South Australia locations
Aims

To assess wether field pea breeding advancements in resistance to blackspot are significant enough to allow management changes to sowing time in this crop.

Key messages
  • WA2211 had lower disease severity and slower build up of blackspot than Kaspa and Alma,
    however this was not reflected in final grain yield due to dry spring seasonal conditions.
  • P-Pickel T slows the blackspot epidemic during the early stages of the crop growth. The effect of P-Pickel T wears off and disease levels are no different to untreated controls beyond 12 weeks after sowing.
  • The blackspot epidemic spreads further in the crop during flowering and podding, by spore
    splash (demonstrated by trap plants placed at Kingsford trial). Fungicide sprays at this stage, to stop the infection on upper foliage and stems, may be beneficial in higher rainfall regions. This needs to be tested in trials by timing spraying with spore release.
  • Concept trial methodology was successfully developed to assess wether field pea lines with
    improved blackspot resistance levels can be sown at earlier sowing dates than currently
    recommended. However further evaluation is required on WA2211 to assess wether its black spot resistance improvement is significant enough due to the dry seasonal conditions which prevailed in 2007 . This will occur again in 2008.
  • The importance of an additive effect of varietal improvement, seed dressing and foliar sprays in allowing earlier sowing is not fully understood and requires further evaluation in a year more favourable for disease infection and spread.
