“…The results suggest that BYDV infections affect grain yield of wheat cultivars to different extents and wheat cultivars may react differently with interactions between BYD-disease and FHB. Koch and Huth (1997) reported that double infections of winter wheat cultivars Orestis and Kraka with BYDV and F. culmorum had significantly greater effects on the yield of wheat plants than single infections.…”

“…Study of effects of BYDV infection in oats and durum wheat on the development of root rot disease caused by Cochliobolus sativus showed that plants diseased by both pathogens were more severely affected than plants infected by each pathogen alone (Scott, 1968). Koch and Huth (1997) concluded that susceptibility of wheat plants to F. culmorum would be increased in epidemic years of BYDV.…”

Interactions between Barley yellow dwarf virus (BYDV) and Fusarium species causing Fusarium head blight (FHB) in winter wheat cvs Agent (susceptible to FHB) and Petrus (moderately resistant to FHB) were studied over three years (2001)(2002)(2003) in outdoor pot experiments. FHB developed more rapidly in cv. Agent than in cv. Petrus. The spread of FHB was greater in BYDV-infected plants than in BYDV-free plants. Thousand grain weight (TGW) was reduced more in Fusarium-infected heads of cv. Agent than in cv. Petrus. A highly significant negative correlation was found between disease index and TGW in cv. Agent (r = )0.916), while in cv. Petrus the correlation was less significant (r = )0.765). Virus infection reduced TGW in cv. Petrus more than in cv. Agent. In plants with both infections, TGW reductions in cv. Petrus corresponded to those of BYDV infection, and in cv. Agent TGW was more diminished than in BYDV infection. Effects of different treatments determined over three years on ergosterol contents in grain were generally similar to effects on disease indices. Grain weight per ear and ear weight of the different treatments of both cultivars largely corresponded with the TGW results. Deoxynivalenol (DON) content in grain of cv. Agent infected with Fusarium spp. was 11-25 times higher compared to the corresponding treatments in cv. Petrus. The DON content in grain of plants of the two cultivars infected with both pathogens was higher than that of plants infected only with Fusarium over the three years.

“…Infection with BYDV‐PAV induces a reduction of root length and of the number of root shoots correlated with a reduction of tiller growth (Hoffman & Kolb, 1997). Damage depends on abiotic and biotic conditions and BYDD can increase susceptibility to frost, drought, and diseases like rusts, snow mould ( Microdochium nivale ) (Collin et al ., 1997) and fusarium ear blight (Koch & Huth, 1997; Liu & Buchenauer, 2005). Yield losses under conditions favourable to epidemics ranged from 5 to 80%, with an average of 30% (Lister & Ranieri, 1995; Perry et al ., 2000).…”

In this study two sources of resistance to Barley yellow dwarf virus (BYDV), both originating from Thinopyrum intermedium, were combined in a single genotype, line ZT, using GISH (genomic in situ hybridization) and a new molecular marker of the partial resistance gene Bdv2. Susceptible wheat cv. Sunstar, the translocation line TC14 carrying Bdv2, the addition line ZH with the group-2 chromosome arm carrying resistance, and line ZT with both resistances were inoculated with five strains of Barley yellow dwarf virus-PAV. The tests confirmed the resistance of TC14 and ZH and revealed an additive effect of the two sources of resistance in ZT. The resistance of line ZT was characterized by a proportion of infected plants significantly lower than the parental lines TC14 and ZH (42% vs. a mean of 76% for the parents) and a very low virus titre (area under the virus concentration progress curve of 1AE2 vs. a mean on 6AE3 for the parents).

“…Fusarium culmorum present itself as a weak pathogen and infects roots more passively with assistance of nematode or wound. Fusarium culmorum may intensify its disease impact through association with other diseases (Koch & Huth, 1997). The absence of microconidia in F. culmorum limits the quantity of propagules or innocula produced for infection.…”

Fusarium wilt of eggplant is a major cause of losses to eggplant production globally. The disease is caused by many Fusarium species. In this study, incidence, diversity and distribution of Fusarium wilt pathogens of eggplants were determined in five communities each from Ashanti, Eastern and Volta Regions of Ghana during the 2017–2019 cropping seasons. Purposive sampling method was used to select 10 eggplant farms infected with Fusarium wilt from each community. Infected eggplants were sampled for isolation and identification of Fusarium species. Fusarium wilt incidence was below 10% in 57.3% of the sampled farms. Differences in disease incidence were significant (p ≤ 0.05) between the Regions. Volta Region recorded the highest disease incidence. A total of eight Fusarium species were isolated. These included F. accuminatum, F. culmorum, F. oxysporum, F. proliferatum, F. poae, F. solani, F. subglutinans, and F. verticillioides. Fusarium solani, F. oxysporum and F. culmorum were the most occurring species, representing 92.79% of the isolates. Six, five and eight Fusarium species were isolated respectively in Ashanti, Eastern and Volta Regions. Inoculum density of the Fusarium species was significantly (p ≤ 0.05) higher in the Ashanti and Eastern Regions than in the Volta Region.
