Carotovorum

carotovorum, a gram-negative bacterium with rod-shaped cells, is globally widespread and attacks a wide range of plants, notably various vegetables. It is reported in tomato crops on all continents. In wet weather in the field, it can cause damage to the stem and/or fruits.This bacterium is a ubiquitous plant pathogen with a wide host range (carrot, potato, tomato, leafy greens, squash and other cucurbits, onion, green peppers, African violets, etc.), able to cause disease in almost any plant tissue it invades.The main symptoms caused by Pectobacterium carotovorum include wilting and water-soaked lesions, which may lead to stem collapse. Soft rot symptoms may include browning of stem and pith in tomatoes, especially when ripe fruit is infected. Changes develop quickly after stem collapse, such as skin folding and cracking followed by development of creamy white ooze. Water-soaked lesions may develop on the outside of fruits and vegetables. Over time, these lesions will sink and may form pits as the bacteria rots away the middle lamella. Cuttings from ornamental plants will develop a crown rot that will extend 5 to 10 cm up the stem from the base of the plant. Later in development, vascular infections and stem rot are typically characterized by vascular browning, wilting, darkening, water-soaked stems and leaves, and total plant collapse. These symptoms develop within 24 to 48 hours after infection. Vascular infections that occur when conditions for disease development are not ideal may lead to stunting and yellowing. A foul odor can also occur when secondary organisms invade the infected tissues.
