Identification Symptoms

  • Leaf spots and blight on the foliage.
  • The disease first becomes visible as small, isolated, scattered pale brown spots on the leaf.
  • Spots are irregular, brown to dark brown in colour, and with concentric rings inside the spot.
  • Often several spots coalesce to form large patches resulting in the leaf blight.
  •  Lowest leaves are attacked first and the disease progresses upwards.
