“…Several of the Fusarium species identified in the present study are reported to be pathogenic to soybean. For instance, F. solani , F. oxysporum , F. proliferatum , F. graminearum and F. sporotrichioides are known causal agents of soybean root rot (Abdelmagid et al, 2020; Broders et al, 2007; Chang et al, 2015; Díaz Arias, Leandro, et al, 2013; Díaz Arias, Munkvold, et al, 2013; Farias & Griffin, 1989; Killebrew et al, 1993; Pioli et al, 2004; Rizvi & Yang, 1996). Fusarium redolens has been reported to cause root rot in Minnesota soybean fields (Bienapfl et al 2010).…”

Aims To isolate and characterize fungi associated with diseased soybean seedlings in Midwestern soybean production fields and to determine the influence of environmental and edaphic factors on their incidence. Methods and Results Seedlings were collected from fields with seedling disease history in 2012 and 2013 for fungal isolation. Environmental and edaphic data associated with each field was collected. 3036 fungal isolates were obtained and assigned to 76 species. The most abundant genera recovered were Fusarium (73%) and Trichoderma (11.2%). Other genera included Mortierella, Clonostachys, Rhizoctonia, Alternaria, Mucor, Phoma, Macrophomina and Phomopsis. Most recovered species are known soybean pathogens. However, non‐pathogenic organisms were also isolated. Crop history, soil density, water source, precipitation and temperature were the main factors influencing the abundance of fungal species. Conclusion Key fungal species associated with soybean seedling diseases occurring in several US production regions were characterized. This work also identified major environment and edaphic factors affecting the abundance and occurrence of these species. Significance and Impact of the Study The identification and characterization of the main pathogens associated with seedling diseases across major soybean‐producing areas could help manage those pathogens, and devise more effective and sustainable practices to reduce the damage they cause.

“…The pathogens associated with the dried-shrink disease are known to cause various diseases on many host plants. For example, F. sporotrichioides causes soybean root rot (Abdelmagid et al, 2020); it is commonly found on cereals and is known as a toxin-producing pathogen (Abramson, 1999). F. oxysporum, F. camptoceras and other fungi of this genus cause vascular wilt of babaco (Vasconcellea heilbornii var.…”

Sea buckthorn (Hippophae rhamnoides L.) is a native species in various regions of Asia and Europe. It is cultivated as a multipurpose horticultural species in northern temperate regions of Europe, Asia, and North America with large economic potential used for food, pharmacology, cosmetics, and environmental conservation. Diseases in natural populations and managed landscapes have increased, endangering sea buckthorn growth and cultivation worldwide. This review article focuses on sea buckthorn canker, wilt and decline diseases caused by pathogenic fungi, their distribution, hosts of involved pathogenic fungi and symptoms. Published information on sea buckthorn fungal diseases is available only about a few diseases, such as wilt (Verticillium dahliae), the dried-shrink disease caused by various fungi and abiotic factors, and stem canker (Hymenopleella hippophaeicola, Cytospora spp., Stigmina sp.). Some fungi reported on sea buckthorn are poorly studied, or the sea buckthorn is a newly discovered host, as in the case of Eutypa spp. The most often reported symptoms of these diseases are cankers and cracks on trunks and main branches, dead buds and leaves, necrosis of various tissues on branches, and root necrosis, resulting in the death of the shrubs. In general, the fungal diseases on sea buckthorn are not sufficiently addressed, and more research is needed.

Fusarium root and crown rot (FRCR) negatively impact several economically important plant species. Cover crops host different soil and residue microbiomes, thereby potentially influencing pathogen load and disease severity. The carryover effect of cover crops on FRCR in barley and soybean was investigated. Field trials were conducted in Prince Edward Island, Canada. Two cover crops from each plant group, including forbs, brassicas, legumes, and grasses, were grown in a randomized complete block design with barley and soybean planted in split plots the following year. Barley and soybean roots were assessed for FRCR through visual disease rating and Fusarium spp. were isolated from diseased tissue. Fungal and bacterial communities in cover crop residues were quantified using amplicon sequencing. The disease-suppressive effects of soil were tested in greenhouse studies. The results indicated that sorghum-sudangrass-associated microbiomes suppress Fusarium spp., leading to reduced FRCR in both barley and soybean. The oilseed radish microbiome had the opposite effect, consequently increasing FRCR incidence in barley and soybean. The results from this study indicate that cover crop residue and the associated soil microbiome influence the incidence and severity of FRCR in subsequent crops. This information can be used to determine cover cropping strategies in barley and soybean production systems.
