Epidemiology of Fusarium oxysporum causing root and crown rot of cannabis (Cannabis sativa L., marijuana) plants in commercial greenhouse production
TLDR
Findings indicate that F. oxysporum is present in several commercial production facilities in Canada and reduces root development and establishment of rooted cuttings, and causes yellowing and stunting on flowering plants of many cannabis strains.Abstract:
Fusarium oxysporum causes root browning and crown infection on marijuana (Cannabis sativa L.) plants, resulting in stunted growth, yellowing of leaves, and plant death. Pathogen presence and divers...read more

First report of Fusarium proliferatum causing crown and stem rot, and pith necrosis, in cannabis (Cannabis sativa L., marijuana) plants
TL;DR: Pathogenicity studies confirmed the ability of F. proliferatum to cause symptoms of wilting, leaf and pith necrosis, and plant death on cuttings, rooted plants and stock plants.
Journal ArticleDOI
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.

The bud rot pathogens infecting cannabis (Cannabis sativa L., marijuana) inflorescences: symptomology, species identification, pathogenicity and biological control
Zamir K. Punja,Li Ni +1 more
TL;DR: Pathogenicity studies conducted on fresh detached cannabis buds inoculated with spore suspensions or mycelial plugs showed that B. cinerea, S. sclerotiorum and F. graminearum were the most virulent, while B. porri and D. eres caused significantly less bud rot.

Multiple evolutionary origins of the fungus causing Panama disease of banana: Concordant evidence from nuclear and mitochondrial gene genealogies
TL;DR: Testing whether lineages of the Panama disease pathogen have a monophyletic origin by comparing DNA sequences of nuclear and mitochondrial genes indicates Panama disease of banana is caused by fungi with independent evolutionary origins.

Pathogen profile update: Fusarium oxysporum
TL;DR: More than 120 different formae speciales have been identified based on specificity to host species belonging to a wide range of plant families as mentioned in this paper, which can cause severe losses in many vegetables and flowers, field crops, such as cotton, and plantation crops such as banana, date palm and oil palm.

Antibiosis, mycoparasitism, and colonization success for endophytic Trichoderma isolates with biological control potential in Theobroma cacao
Bryan A. Bailey,Hanhong Bae,M.D. Strem,J. Crozier,Sarah E. Thomas,G.J. Samuels,B.T. Vinyard,K. A. Holmes +7 more
TL;DR: Most of the isolates studied were able to establish an endophytic relationship with cacao by colonizing the above ground portions of the cacao seedling, and exploitation of this characteristic could lead to the development of novel biocontrol strategies for control of cacao diseases.
