“…In spite of partial Triticum resistance criteria to Fusarium are most generally found under field factors (Covarelli et al, 2015;Dweba et al, 2017;Fernando et al, 2021), they are precisely and correctly distinguished under controlled conditions controlling all abiotic and biotic experimental conditions (Sakr, 2021c). In respect to multiple Si treatments in six T. durum and T. aestivum cultivars, the average scores of the reduction of Fusarium incidence, for model I, and Fusarium severity, for type II, in wheat kept in the growth chamber and field (Sakr and Kurdali, 2022) conditions ranged from (18.3% and 18.7%) and (21.2% and 21.3%), respectively. This result indicates the significance of environmental conditions on wheat defense responses against infection by FHB pathogens.…”

“…Because of the loss of commercial wheat genotypes with favorable genetic resistance to head blight (Buerstmayr et al, 2020), a practical alternative was effectively undertaken to manage mineral nutrition by Si feeding through root systems in order to enhance Fusarium resistance in Triticum (Dallagnol et al, 2020). Recently, multiple Si treatments via roots applied constantly into Triticum host was found to enhance wheat resistance to FHB infection under filed conditions (Sakr and Kurdali, 2022). However, uncontrollable climate factors such as humidity, temperature, and the parallel existence of other organisms in the field greatly influenced FHB development in wheat supplied with Si (Sakr and Kurdali, 2022), resulting in difficulties to distinguish precisely and correctly resistance components involved in the expression of +Si wheat to Fusarium infection (Pazdiora et al, 2021).…”

“…Reports under filed conditions to detect the effectiveness of Si for the management of host damages, Si value does not reach 1.67 mM (Deshmukh et al, 2016). Such Si concentration reduced FHB symptoms following several applications thought root and foliar systems in wheat and barley under in vitro, growth chamber and filed conditions (Sakr, 2021b(Sakr, ,c, 2022Sakr and Kurdali, 2022). Si treatment via root at a value of 1.7 mM gave the best results in terms of Si accumulation in wheat and management of Blumeria gramini sf.…”

“…Root and foliar Si applications enhanced wheat resistance to Fusarium infection under in vitro, controlled and field conditions (Sakr, 2021b(Sakr, ,c, 2022Pazdiora et al, 2021). Recently, the effect of multiple Si treatments via roots applied constantly into Triticum host has been investigated so far in the field (Sakr and Kurdali, 2022), although not in details. While expression of Fusarium damages in plants treated with Si is highly affected by climate factors (Buerstmayr et al, 2020), the testing of multiple Si root applications on enhancing wheat resistance in environments controlling strictly all biotic and abiotic factors would be of great importance.…”

Fusarium head blight (FHB), provoked by various Fusarium organisms, is among the main damages presenting in all Triticum spp.-cultivation regions. Silicon (Si) application of Triticum host as sustainable disease management has been shown to increase host resistance to FHB. It has been approved that Si rate does not reach 1.67 mM for the prohibition of host diseases. To test the effect of multiple Si root applications on enhancing wheat resistance in controlled environments, six Triticum lines with different resistances to head blight and inoculated with various Fusarium pathogens with varied aggressiveness were grown in growth chamber amended with 1.7 mM Si. The reduction in disease symptoms due to the effect of Si was expressed as FHB incidence (DI, Type I resistance), FHB severity (DS, Type II) and Area Under Disease Progressive Curve (AUDPC) evaluated on the basis of DI and DS. Overall, DI, DS and AUDPC calculated on the basis of DI and DS were reduced by 21.2%, 21.3%, 20.2% and 20.3% in Si treatments in comparing with -Si wheat plants. In comparing with non-Si applied hosts, Si application strongly enhanced all tested components of the wheat resistance, reinforcing the theory that the tested Si concentration is needed for the effective resistance to be manifested to FHB. Sensitive to moderately sensitive and sensitive lines could reduce FHB damage assessed by DI, DS and AUDPC calculated on the basis of DI and DS to a line exhibited a resistance with moderate level that were not applied with Si. Thus, our results showed that Si increased resistance measured by FHB incidence, FHB severity, AUDPC DI, and AUDPC DS on less resistant wheat lines to levels equivalent to those of lines exhibited a resistance with moderate level to FHB and not applied with Si, postulating theoretically that Si absorption by the roots is necessary to avoid negative impact of Fusarium infection. To our best knowledge, this study involved controlled-environmental tests presented the primary pathogenic evidence linked with the feeding of multiple Si applications in wheat hosts infected by Fusarium. Overall, our results lead to the conclusion that, when commercial wheat lines with elevated levels of resistance are not accessible to farmers in areas where soil is Si deficient, multiple Si fertilization through the root system is a promising component in the integrated host management to increase wheat resistance to FHB.

Background: Silicon (Si) amendment plays an important role in enhancing the resistance of several plant species to diverse pathogens. To date, a few studies have focused on how Si application helps barley, a higher Si absorber and accumulator monocot, to resist fungal diseases, including Fusarium head blight (FHB), which reduces the quality and safety of harvested products worldwide. However, no study has ever been conducted to demonstrate Si's ability to suppress FHB development in barley heads under uncontrolled climatic conditions. Materials and Methods: This 2-year field study elucidated the effect of multiple Si applications at 1.7 mM via roots in two barley cultivars, Arabi Aswad (AS moderately resistant) and Arabi Abiad (AB moderately susceptible), to control four Fusarium species with diverse pathogenicity. The incidence of FHB (DI type I resistance), severity of FHB (DS type II), and Fusarium-damaged kernels (FDK type III) were also tested to describe the nature of the Si-enhanced barley resistance. Results: Si treatment at 1.7 mM under soil culture decreased FHB development by enhancing all resistance types measured in the present research. DI, DS, and FDK were reduced by 18.7%, 20.3%, and 20.2%, respectively, in Si-Fusarium-inoculated treatments relative to fungal-inoculated controls. Si absorption in barley strengthened the defense system measured by type I and type II on AB to a level comparable to AS not amended with Si. Irrespective of the barley cultivar, however, Si resulted in a quasi-similar reduction of FDK. Importantly, Si treatment at 1.7 mM decreased the damage of FHB in previous analyses conducted on AS and AB under in vitro and growth chamber environments, showing that Si enhanced the expression of resistance to FHB infection in seedlings and adult barley plants. Conclusion: All of these results are promising outcomes for the application of Si as a safe and effective method against Fusarium species. This study provides new insights into the potential of multiple Si applications at 1.7 mM via roots for boosting barley’s resistance to FHB with a bright prospect for Si use in barley cultivation under field conditions.
