“…The average growth rate at 15ºC and 25ºC was 5.32 mm/day and 13.5 mm/day, respectively. Similar growth rates (5.6 mm/day at 15°C and 12.8 mm/day at 25°C) were reported by Hudec and Muchova [40]. Hope et al [41] showed that growth as well as DON production was optimised at 25ºC.…”

“…MGA combined with antibacterial agents is a selective medium for isolation of Fusarium species (Castellá et al, 1997). The petri dishes were incubated at 20°C, since at this temperature F. avenaceum, F. culmorum, F. graminearum, F. poae and M. nivale are able to grow in vitro (Hudec and Muchová, 2010;Brennan et al, 2003). All Fusarium colonies were transferred to PDA (potato dextrose agar, Oxoid, Belgium) medium for further identification.…”

Connection between primary Fusarium inoculum on gramineous weeds, crop residues and soil samples and the final population on wheat ears in Flanders, Belgium

Fusarium head blight (FHB) is a devastating disease of wheat, which is influenced by weather conditions and agronomic factors. Since FHB is a mostly monocyclic disease, the quantity of primary inoculum is a key factor influencing the FHB incidence. To investigate the connection between the primary Fusarium inoculum and the final population on wheat ears, naturally occurring populations of Fusarium avenaceum, Fusarium culmorum, Fusarium graminearum, Fusarium poae and Microdochium nivale were studied at eight locations in Flanders, Belgium. To determine the composition of the primary inoculum in November 2008, gramineous weeds, wheat residues, maize residues and soil samples were examined. In July 2009, wheat ears were examined to gain insight into the composition of the population at the end of the growing season. Comparing both populations can give an indication to what extent the primary inoculum in November 2008 contributes to the final FHB population in July 2009. Fusarium species residing saprophytically on gramineous weeds and crop residues or species persisting in soil as chlamydospores certainly contribute to the primary inoculum that will lead to infection of cereal crops grown on that field. Knowledge of the correlation between the primary inoculum and the composition of the FHB population at the end of the growing season can be important to predict the occurrence of FHB contamination and to implement control strategies for Fusarium Head Blight.

“…Both pathogens are important nontoxigenic fungal pathogens of many cereal crops causing seedling blight, foot rot and also belong to the Fusarium head blight fungal complex (Amein et al, 2007;Walker et al, 2009;Nielsen et al, 2011;Jørgensen et al, 2012). Microdochium fungi are associated with retardation of seed germination (Hudec, Muchova, 2010) and significant yield losses (Humphreys et al, 1995;Amein et al, 2007).…”

Seedling blight, mostly caused by Fusarium spp. and Bipolaris sorokiniana, is a common disease in spring cereals. This research confirmed the presence of Microdochium fungi in a complex of seedling blight causative agents. Pathogens Microdochium nivale and M. majus in the seed and in stem base of seedlings of spring barley, spring wheat, spring triticale and spring oats were identified and quantified using a quantitative real-time polymerase chain reaction (qPCR) in 2013-2015. Both species were detected in the seed of all spring cereals tested. The amount of M. nivale and M. majus DNA was the highest in seeds of barley. Both Microdochium pathogens were present in the stem base of seedlings of all spring cereals tested; however, a high variation between cereal species and years was established. In most cases, the quantity of M. nivale DNA was the lowest in the seedlings of oats, while that of M. majus -in the seedlings of barley compared to the other cereal species tested. Higher contents of M. majus and M. nivale DNA were identified in the stem base of the seedlings emerged from untreated seeds compared with the seedlings emerged from the fludioxonil-treated seeds. However, the effect of tebuconazole on the reduction of M. nivale and M. majus DNA was inconsistent. Our findings suggest that M. nivale and M. majus occur in the seed of spring cereals and cause seedling blight, therefore research on these pathogens needs to be extended.
