3.  Small, pinhole-size spots are initially seen on young leaves
less than a month.
 The spots become transparent, larger, and light brown.
 After 7 days, the lower leaf surface develops blister like
symptoms, with dark green, water soaked zones
surrounding the blisters.
 Following release of fungal spores, the blisters become
white and velvety.
 Subsequently the blister turns brown, and young infected
stems become bent and distorted and may break off or die.
