Soybean (Glycine max (L.) Merr.) is native to East Asia including Korea and is widely grown and consumed as an edible seed. In August 2011, following a prolonged period of cool and moist weather, zonate leaf spots were observed in local soybean (cultivar unknown) planted in a mountainous area of
A three-year survey from 2010 to 2012 was conducted in Kansas to investigate the identity and diversity of seedborne Fusarium spp. in soybean. A total of 408 soybean seed samples from 10 counties were tested. One hundred arbitrarily selected seeds from each sample were surface-sterilized for 10 min
In a survey for Fusarium root rot, soybean plants were sampled from eight counties across Iowa in 2008 to 2009. Fusarium isolates were recovered from surface-sterilized symptomatic and asymptomatic root tissue by culturing on peptone PCNB agar (2). Single-spore isolates were transferred to carnation
During 2007 to 2009, symptomatic and asymptomatic soybean plants were collected from fields in 18 Iowa counties. Fusarium isolates were recovered from surface-sterilized root tissue on peptone PCNB agar (2). Single-spore isolates were transferred to synthetic low nutrient agar (SNA) overlain with
Fusarium spp. are widespread soilborne pathogens that cause important soybean diseases such as damping-off, root rot, Fusarium wilt, and sudden death syndrome. At least 12 species of Fusarium, including F. proliferatum, have been associated with soybean roots, but their relative aggressiveness as
Endophytic fungi are ubiquitous and live within host plants without causing any noticeable symptoms of disease. Little is known about the diversity and function of fungal endophytes in plants, particularly in economically important species. The aim of this study was to determine the identity and
Charcoal rot of soybean (Glycine max (L.) Merr.), incited by Macrophomina phaseolina (Tassi) Goidanich, is commonly found in much of the southern soybean production region of the United States, where it can be a major contributor to yield loss in warm, dry seasons (4). The disease has also been
Diaporthe caulivora and D. longicolla are the causal agents of stem canker of soybean (Glycine max L.). Accurate identification of stem canker pathogens upon isolation from infected soybean plants is difficult and unreliable based on morphology. In this study, two TaqMan probe-based quantitative
Genera, Diaporthe and Phomopsis, from an important pathogenic complex of soybean (Glycine max) throughout the world, cause reductions in plant stands, yield, and seed health and quality (1). In a study of the Diaporthe/Phomopsis complex in Taiwan in March 2008, four stem samples with black fruiting
Fifty-nine soybean samples (Glycine max) of various varieties, grown in various agro-ecological zones of Ghana, and harvested in 1995 and 1996, were collected during May through June 1996 and sent to Denmark for analysis. Seed samples were analyzed by the blotter method: seeds were placed on three
Soybean (Glycine max [L.] Merr.) is economically the most important protein crop grown worldwide. However, Europe largely depends on soybean imported from the Americas (European Commission 2019; Haupt and Schmid 2020). In Germany, soybean production was not formally recorded before 2016, but
Soybean (Glycine max L. Merr.) is an important leguminous crop for Colombia, given the growing demand from the livestock, poultry, and aquaculture industries. About 80 percent of Colombian soybean production is in the State, or Department, of Meta, located in the Eastern Plains region, or
Mature cowpea (Vigna unguiculata (L.) Walp.) pods with scattered, irregular black spots, similar in appearance to those found on mature soybean (Glycine max (L.) Merr.) pods infected with Phomopsis longicolla T. W. Hobbs, were observed in three fields in Oktibbeha County, MS, in September 1994. In a
During August 2004, Cylindrocladium parasiticum Crous, M.J. Wingf., & Alfenas (teleomorph Calonectria ilicicola Boedijin & Reitsma) was isolated from peanut (Arachis hypogaea L.) cv. NC 7 taken from an irrigated field in Terry County, TX. On 24 September, the mean length of patches with
Black spot disease on field pea (Pisum sativum) in Australia is generally caused by one or more of the four fungi: Mycosphaerella pinodes (anamorph Ascochyta pinodes), Phoma medicaginis var. pinodella (synonym Phoma pinodella), Ascochyta pisi, and Phoma koolunga (1,2,4). However, in 2010 from a
