“…Detrimental impact on ERG content confirmed a significant disruption or biosynthesis blockage within the plasma membrane of F. culmorum. This finding is in agreement with some of the previous studies that have reported a decrease in ERG content in infected samples after the application of plant extracts (Abhishek et al, 2015;Uwineza et al, 2022). Leaf extract of Solanum torvum Swartz.…”

“…Leaf extract of Solanum torvum Swartz. decreased ERG production by the Fusarium verticillioides strain (Abhishek et al, 2015). Previous in vitro study also showed L. album flower extract activity against F. culmorum and F. proliferatum, reducing ERG content (Uwineza et al, 2023).…”

“…Ergosterol, being integral to fungal cell membranes, serves as an indicator of fungal biomass and is vital for maintaining cell function and integrity (Perkowski et al, 2008;Uwineza et al, 2022). Severe ERG depletion may influence cell growth and proliferation (Abhishek et al, 2015). Here, the effect of L. album extract was evident, as shown by the ERG reduction in infected seedlings.…”

Fusarium culmorum is a major wheat pathogen, and its secondary metabolites (mycotoxins) cause damage to plants, animals, and human health. In the era of sustainable agriculture, eco-friendly methods of prevention and control are constantly needed. The use of plant extracts as biocontrol agents has gained popularity as they are a source of active substances that play a crucial role in fighting against phytopathogens. This study evaluated the impact of Lamium album on wheat seed germination and seedling growth. In a pot experiment, the effect of L. album on wheat seedlings artificially inoculated with F. culmorum was evaluated by measuring seedling growth parameters, and by using chromatographic methods, ergosterol and mycotoxins levels were analyzed. The results showed that the phytotoxic effect of L. album flower extracts on wheat seed germination and seedling growth was concentration dependent. The radicle length was also reduced compared to the control; however, L. album did not significantly affect the dry weight of the radicle. A slight phytotoxic effect on seed germination was observed, but antifungal effects on artificially infected wheat seedlings were also confirmed with the reduction of ergosterol level and mycotoxins accumulation in the roots and leaves after 21 days of inoculation. F. culmorum DNA was identified in the control samples only. Overall, this study is a successful in planta study showing L. album flower extract protection of wheat against the pathogen responsible for Fusarium crown and root rot. Further research is essential to study the effects of L. album extracts on key regulatory genes for mycotoxin biosynthetic pathways.
