Bacterial wilt of carnation

Bacterial wilt of carnations (also known as carnation bacterial wilt) is a bacterial disease caused by the plant pathogen Trinickia caryophylli (often referred to as Burkholderia caryophylli). Previously named Pseudomonas caryophylli, the pathogen is an aerobic gram negative bacteria known for only being capable of entering its host through wounds. Once inside the host, it colonizes the vascular system and roots causing symptoms such as, internal stem cracking, yellowing of the leaves, wilting, and the development of cankers. As a bacterial disease, bacterial wilt of carnations can also be characterized by signs such as bacterial streaming, and bacterial ooze.
