Aims

To investigate grey speck disease of oats on the south east of South Australia.

Key messages
  • Manganese deficiency has been identified on light volcanic soils from Mounts Gambier and Schank, and heavy black soils from drained swamps near Penola.
  • These soils are alkaline.
  • Symptoms first appear as oval dead spots on the second leaf, especially along the margins (not on the first leaf).
  • Availability of manganese is reduced in the alkaline soil.
  • The deficiency can be cured by the application of manganese sulphate.
