The tomato bacterial speck disease agent, Pseudomonas syringae pv. tomato, causes severe damage in nurseries, commercial greenhouses and several regions with highly rainy summers.

This article is a list of diseases of tomatoes (Solanum lycopersicum). Bacterial Speck Disease of Tomato: An Insight into Host-Bacteria Interaction. Pseudomonas syringae strain DC (Pst DC) causes bacterial speck disease on tomato.

The pathogenicity of Pst DC depends on both the type III secretion system that delivers virulence effector proteins into host cells and the phytotoxin coronatine (COR), which is thought to mimic the action of the plant hormone jasmonic acid (JA).

While leaf wetness is required for both bacterial spot and bacterial speck infection, cooler temperatures (55 F. Pseudomonas syringae pv. tomato, responsible for bacterial speck, causes small, irregular, brown spots 1–2 mm in diameter (Photos).

These spots are gradually surrounded by a defined yellow halo (Photo ). If conditions are particularly wet, they expand, fuse together and affect whole sectors of the leaf.

Bacterial speck of tomato caused by Pseudomonas syringae pv. tomato is an important disease in many tomato growing areas. The pathogen is known to comprise two races – R0 and R1. Bacterial speck This disease, caused by the bacterium Pseudomonas syringae pv.

In temperate regions, speck (caused by Pseudomonas tomato) was the main bacterial disease, and a second race of this bacterium has overcome the resistance used in some production areas. Bacterial canker (due to Clavibacter michiganensis) can be devastating when it is transmitted mechanically during cultivation operations.The inoculum of Pseudomonas tomato (Okabe) Alstatt, causal agent of bacterial speck, was sprayed on plants before or after exposure to acidic rain of pH, andas well as on plants not exposed to the simulated acidic rain.

Speck symptoms (small, dark, brown spots with yellow halos) were found on all inoculated plants.During July,tomatoes growing at Mola di Bari, Italy, were widely affected by a fruit-spotting. Inoculations of healthy tomato fruits with a bacterium isolated from infected material gave rise to typical symptoms.

The condition was identified from the symptoms in natural and experimental inoculations and from the characters of the causal organism as bacterial speck (Pseudomonas Author: A. Ciccarone, A.
