Verticillium longisporum, also known as Verticillium Wilt, is a fungal plant pathogen that commonly infects canola. V. longisporum can attack other brassica plants as well as woody ornamentals. A main symptom of the infected plant is wilting. In America, V. longsiporum primarily effects eudicot plants. This pathogen can be very devastating and ...
Wilt itself is the most common symptom, with wilting of the stem and leaves occurring due to the blockage of the xylem vascular tissues and therefore reduced water and nutrient flow. In small plants and seedlings, Verticillium can quickly kill the plant while in larger, more developed plants the severity can vary.
The bacteria need a film of water to facilitate infection. The bacteria can also be transmitted from one plant to another when beetles feed on an infected plant and the bacteria becomes attached to the beetles mouthparts. [4] The bacteria Ralstonia solanacearum and related species cause bacterial wilt of bananas and plantains. [5]
Verticillium wilt (class incertae sedis: family Verticillium) Verticillium dahliae Sooty moulds Alternaria species – Sooty mould appears as black, dry powder on leaves similar to chimney soot. Many sooty moulds grow on the honeydew (frass) produced by sap-sucking insect such as aphids and soft scales.

Verticillium dahliae invades the host plant via natural wounds or by penetrating the root tissue. Following entry, the pathogen enters the xylem where conidia are spread throughout the host. The plant responds to the pathogen by producing tyloses which block the xylem, resulting in decreased water flow and wilting.
