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:
Twig blight
Twig blights appear in the adventure "Lost Mine of Phandelver", included in the 5th edition "Dungeons & Dragons Starter Set" (2014). They reappear in the Sunless Citadel, as part of "Tales from the Yawning Portal", as well as the 5th edition "Monster Manual" alongside the needle blight and the vine blight, the only blight capable of speech. The Tree Blight appears in "Curse of Strahd".
