Pea yield decline syndrome in South Australia locations

To establish the importance of manganese and zinc to pea yield decline.

Key messages
  • A survey of the incidents of black spot and downey mildew on field pea was conducted in South Australia.
  • Analysis of manganese and zinc implants was conducted, along with a field trial with manganese and zinc addition.
  • Effect of micronutrients on the diseases was not clear but manganese concentrations in plants was negatively correlated with blackspot.
  • Deficiencies in zinc were measured but these were not correlated with blackspot or downy mildew.
