“…Some studies focused on the pathogenicity of F. equiseti, where numerous members of the leguminoseae beside some cereals were reported as a host range for F. equiseti causing root rot and damping-off diseases (Rubella et al, 2008). In Algeria,, Bencheikh et al (2020) documented recently the rst report on crown rot and damping-off on durum wheat caused by Fusarium equiseti. In China, the rst report on cauli ower wilt by F. equiseti was mentioned previously in 2017 (Pan-Liang et al 2017).…”

Background: Recently, nanoparticles has proposed as a different and ecofriendly tools for solving many problems in agricultural field. Aim: The current investigation is an attempt to assess the antifungal activity of Copper oxide nanoparticles (CuONPs) against wheat wilt disease. Results: Isolates of Fusarium sp., Alternaria sp. and Rhizoctonia sp. species were recovered from wheat roots showed willt symptoms. Highest frequency (77.12%) was associated to Fusarium sp. Fusarium sp. isolates from pathogenicity test indicated that isolate (F1) out the highest frequency isolates caused high percentage of wilt reached to 65.1%. Molecular identification of F1 isolate was performed using ITS rRNA gene, and confirmed that it belong to F. equiseti. Inhibition (%) of F. equiseti growth was 3.45 and 16.66% at 100 ppm, and it was 74.14 and 78.21% at 400 ppm of CuONPs at 5 and 8 days, respectively. The action mechanism of CuONPs on F. equiseti inhibition was elucidated by transmission electron microscopy. CuONPs induced morphological changes and damage of the cell membranes of the F. equiseti. Healthy wheat plant without F. equiseti infection exhibited 11.24 ug. g-1dry weight of total phenol content (TPC), while infected plant showed highest content 14.25 ug. g-1dry weight. CuONPs at 200ppm induced TPC of infected plant by F. equiseti to 16.67 ug. g-1dry weight. Increment in Peroxidase, polyphenol oxidase, superoxide dismutase activities in wheat plant cultivated in soil inoculated by F. equiseti and amended with 400 ppm of CuONPs were recorded comparatively to wheat plant cultivated in soli inoculated by F. equiseti but without CuONPs. Conclusion:The inhibitory effects of CuONPs are very actual management strategies for the control wheat wilt disease caused by F. equiseti in respective to present and future studies.

“…Waha were moderately sensitive, with an AUDPC1 of 46.5%. The same nding was obtained by Bencheikh et al (2018), where the Waha cultivar was noticed to be considerably more susceptible to the infection of Fusarium chlamydosporum, resulting in the following reduction: 71.15% of FWVS, 75.04% of LRS, and 82.58% of LVS.…”

“…Eleven Fusarium isolates were isolated from the FHB-symptomatic grain samples of durum wheat and ears collected from various north-eastern provinces of Algeria. The set of isolates was taxonomically and molecularly identi ed in previous studies (Bencheikh et al, 2020;Belabed et al, 2022) and is codi ed as follows: F. avenaceum (FusBi7, FusBi21), F. acuminatum (FusBi15, FusBi23, FusBo33), F. culmorum (FusBo59), F. incarnatum-equiseti species complex (FusBi1, FusBi2, FusBi8), F. tricinctum species complex (FusBi6), and F. chlamydosporum species complex (FusBo26). The pathogenicity of Fusarium isolates was estimated through their potential for inducing symptoms (e ciency of infection, severity of disease) in addition to their ability to produce host necrosisinducing mycotoxins (Pariaud et al, 2009).…”

Fusarium is one of the world's most harmful wheat pathogens, causing severe crop diseases like Fusarium head blight (FHB). They constitute a serious threat to the production of wheat by considerably reducing crop yield, quality, and safety due to grain contamination with mycotoxin. The focus of the current study emphasizes aspects related to the pathogenicity and toxigenicity of some FHB isolates recovered from symptomatic Algerian wheat samples. Three genotypes of durum wheat were subjected to two pathogenicity tests (in vitro and in vivo), and the results showed a significant difference in aggressiveness on different phenotypic parameters, indicating intrinsic genetic variation in the host-pathogen interaction. All of the Fusarium isolates tested for mycotoxinogenicity produced Deoxynivalenol, zearalenone, and T-2 toxin. With DON, the most common mycotoxin type, producing 7.128µ/kg in the ELISA test and 373196.19µg/kg by LC-MS/MS, exceeding the European limits (1750µg/kg), the FusBo59 isolate of F. culmorum stands out as the most toxic. Following DON (18.2%) and 3-ADON (9.1%), 15-ADON (63.6%) emerged as the most prevalent toxin in wheat grains, according to a toxin analysis. T-2 and zearalenone (ZEN) were present, but at concentrations below the permissible limits (100µg/kg). On the other hand, F. avenaceum FusBi7 stood out as being the most aggressive, and the Cirta variety was the most tolerant to attacks from the Fusarium isolates studied. Thus, our data demonstrate that disease induction and toxin generation evolve independently of each other.
