The Fusarium solani species complex infecting cannabis (Cannabis sativa L., marijuana) plants and a first report of Fusarium (Cylindrocarpon) lichenicola causing root and crown rot
TLDR
This study demonstrates the first occurrence worldwide of F. lichenicola on cannabis plants, on which it is considered a weak introduced tropical pathogen, likely to have originated from coco coir imported into Canada.Abstract:
Greenhouse-grown cannabis (Cannabis sativa L., marijuana) plants with yellowing, crown rot and root-browning symptoms were sampled from six production facilities during 2019–2020. Among 34 fungal i...read more

Diseases of Cannabis sativa Caused by Diverse Fusarium Species
TL;DR: The robust strategies for disease management are in development for this new crop and have primarily relied on management systems for other crops, but knowledge for control of these important fungal diseases to provide safe products for human consumption is required.

Several Pythium species cause crown and root rot on cannabis (Cannabis sativa L., marijuana) plants grown under commercial greenhouse conditions
TL;DR: Cannabis plants with symptoms of crown rot, root decay, wilting and plant death were sampled during 2018 and 2019 from seven production greenhouses to study the mechanisms behind plant death.

The Fusarium solani species complex: ubiquitous pathogens of agricultural importance
TL;DR: The known molecular mechanisms utilized by members of the FSSC in establishing disease are summarized and phylogenetic analysis has revealed that formae speciales correspond to biologically and phylogenetically distinct species.

Fusarium solani on soybean roots : Nomenclature of the causal agent of sudden death syndrome and identity and relevance of F. solani form B
TL;DR: Two morphological forms of Fusarium solani pathogenic on soybean, forms A and B, were further characterized and distinguished from other fungi and it was concluded that the two fungi are different and distinguishable on the basis of host specialization and the types of symptoms they incite on soy bean.

Analysis of Phylogenetic Relationship of Cylindrocarpon lichenicola and Acremonium falciforme to the Fusarium solani Species Complex and a Review of Similarities in the Spectrum of Opportunistic Infections Caused by These Fungi
TL;DR: Reevaluation of species morphology in light of the molecular findings showed that certain features, especially elongate filiform conidiophores with integrated terminal phialides, facilitate correct microscopic classification of these atypical Fusarium species.
