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:
Puccinia pittieriana
This fungus was first made known to science in 1904 when it was collected from potatoes in cultivation on the slopes of Irazú Volcano in Costa Rica. It was later found on wild potato species such as "Solanum demissum" and on tomato crops. It is now known from Central and South America and from Mexico. Its known hosts now include many wild and cultivated species of "Solanum". This is the only rust fungus that infects tomatoes.
