Verticillium dahliae
species of fungus
Verticillium dahliae is a fungal plant pathogen. It causes verticillium wilt in many plant species, causing leaves to curl and discolor. It may cause death in some plants. Over 400 plant species are affected by Verticillium complex.
Management
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. The exception to this is rotation using broccoli, which has been shown to decrease Verticillium severity and incidence in cauliflower fields. This is likely due to the production of allyl isothiocyanate in broccoli, which can suppress the growth of plant pathogenic fungi.
Seed choice may reduce disease presence. Purchasing seed stock from certified Verticillium-free growers and utilizing resistant or partially resistant cultivars can decrease disease incidence. Even resistant cultivars may show symptoms if the field has a high concentration of Verticillium, so site selection is still essential to minimizing disease incidence.
“Verticillium dahliae” enters the record as species of fungus. Crown Archives preserves that source wording while asking what Verticillium, dahliae and species can confirm, complicate or overturn.
Why this record matters
“Verticillium dahliae” is worth following because a concise public description often conceals a longer documentary argument. Here, Verticillium, dahliae and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Oct 21, 2025. The linked authority identifier is Q2699339. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
