Fireblight

Fireblight was a type of disease which affected plants.

In 2269, during the battle between Spock and Spock One on Organia, Captain James T. Kirk (due to the effects of the thought-shield) saw a baobab-like tree quickly wilt and rot, as if it had been attacked simultaneously by mildew, black spot, canker, fireblight and Titanian mold.
