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 ...
Potatoes grown in Verticillium infested soils may have a reduced yield between 30–50% compared to potatoes grown in "clean" soil. Verticillium wilt has also caused a shift in peppermint cultivation from the Midwest in the mid- to late-1800s to western states such as Oregon, Washington and Idaho, to new, non-infested areas within these states now.

Verticillium nonalfalfae is a soilborne fungus in the order Hypocreales. It causes verticillium wilt in some plant species, including Ailanthus altissima . [ 1 ] [ 2 ] The fungus produces a resting mycelium characterized by brown-pigmented hyphae .
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 wilt is a disease that can affect over 400 different eudicot plants, many of which are economically important worldwide. Several characteristics of Verticillium make it difficult to manage: prolonged survival in soils without the presence of a host, inaccessibility during infection, a wide host range, and limited resistance in host germplasm.
Verticillium dahliae has a wide host range and can persist as microsclerotia in the soil for years, so management via fallowing or crop rotation generally has little success. [2] The exception to this is rotation using broccoli, which has been shown to decrease Verticillium severity and incidence in cauliflower fields. [3]
Stephen Wilhelm (19 April 1919, Imperial, California – 15 July 2002, Walnut Creek, California) was a professor of plant pathology, known for his success in controlling Verticillium wilt. His research on plant hybridization and soil fumigation contributed to revolutionary developments in the strawberry and raspberry industries. [1] [2]
