Blight
Blight is a rapid and complete chlorosis, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs. Accordingly, many diseases that primarily exhibit this symptom are called blights. Several notable examples are:
Hevea brasiliensis
The cultivation of the tree in South America (Amazon) ended early in the 20th century because of blight. The blight, called South American leaf blight, is caused by the ascomycetes, "Microcyclus ulei" or "Pseudocercospora ulei".
