Chickpea: Identifying sclerotinia


There are two Sclerotinia spp that attack chickpeas and they can be distinguished by the size of their sclerotes (survival structures).

  • S. sclerotiorum produces large irregular shaped sclerotes 5–10 mm in diameter as high up as 20–30 cm on the stem
  • S. minor produces sclerotes that are angular and much smaller, rarely larger than 2–3 mm in diameter
  • S. sclerotiorum killed these plants – eventually the whole crop was lost. (Photo: Kevin Moore)
