Minor Pest Title

Early blight or Alternaria leaf and fruit spots (Alternaria spp.)

Minor Pest Description

Several Alternaria spp. are involved. These include A. melongenae, A. solani and A. tenuis. They cause leaf spotting and fruit rots. They produce leaf spots with concentric rings. The spots are mostly irregular, 4 to 8 mm in diameter and may enlarge and cover a large area of the leaf blade. Severely infected leaves drop off prematurely resulting in the reduction of yield. Fruit spots are circular, brown, dry and hard.
