“…among pulse and cereal crops has been reported [36]. The fairly wide host range of F. proliferatum found in this study was not necessarily unexpected, given the reports of this pathogen being present on many host species [8,12,15,17,37]. However, the virulence observed on the soybeans, lupine, canola, lentils, and peas, and, to a lesser extent, on the barley, wheat, and faba beans, is concerning within a western Canadian context, since these represent most of the crops that can be grown in this region [16,38,39].…”

“…Molecular identification and phylogenetic analysis based on the translation elongation factor 1-alpha (TEF-1α) sequences, along with mating studies on multiple isolates from diverse hosts and locations, have suggested that there is no relation between F. proliferatum isolates and their hosts or geographic origins [18,37,55,56]. Nevertheless, an evaluation of vegetative compatibility among isolates of F. proliferatum indicated that isolates recovered from maize, onion, sugarcane, and rice could be classified into different vegetative compatibility groups (VCGs), indicating a correlation between VCGs and host preferences [12]. The fungal isolate used in the current study was obtained from canola [26], and assessments of the host responses to additional isolates collected from different species may be warranted to confirm the reactions observed here.…”

Fusarium proliferatum is also regarded as an important pathogen in the fruit industry, causing significant economic losses in bananas [13] and red-fleshed dragon fruit [14].…”

Fusarium proliferatum is associated with the root rot of many plant species, but knowledge of its impact on western Canadian field crops is limited. This study assessed the host range of this fungus and its effect on plant emergence, plant height, and shoot and root dry weights in repeated greenhouse experiments with wheat, barley, faba beans, peas, lentils, canola, lupine, and soybeans. Infection was confirmed via PCR, and principal component analysis determined the utility of different parameters in assessing host responses. All crops were at least partly susceptible, developing mild to severe disease at the seedling and adult stages, and showing significant reductions in growth. In general, the barley and wheat demonstrated higher tolerances to infection, followed by the faba bean and the pea. The soybean, canola, lupine, and lentil were most susceptible. The canola and the soybean were particularly vulnerable to F. proliferatum at the pre-emergence stage, while infection greatly reduced the lentil’s biomass. Reductions in the barley’s emergence and other growth parameters, however, occurred only under a high inoculum concentration. Variability in root rot severity among cultivars of the same crop indicated some diversity in host reactions within species. Nonetheless, the absence of fully-resistant crops may pose challenges in managing F. proliferatum in western Canadian cropping systems.

“…For instance, in a study examining the inhibitory effect of the synthetic fungicide Thiabendazole on A. flavus, the EC 50 and MIC indices were 650 ppm and 1635 ppm, respectively, which closely aligned with the results obtained from the positive control used in our study. [42] As mentioned previously, our findings related to the inhibitory effect of thyme essential oil on A. flavus species demonstrated a significantly higher inhibitory effect based on the two mentioned indices (EC 50 = 255 ppm, MIC = 648 ppm), representing more than a 100 % increase in inhibitory effect. A comparison with another similar study that examined the fungistatic effect of the thymol chemotype of T. daenensis against A. niger revealed a similar MIC measure (600 ppm).…”

The study focused on utilizing the anti‐fungal and antioxidant properties of essential oils from Thymus daenensis Celak. subsp. daenensis to combat the growth of mycotoxin‐producing Aspergillus species, including A. flavus, A. parasiticus, and A. niger, all common food and agricultural contaminants. The essential oil exhibited significant antifungal activity, accompanied by notable antioxidant properties. The essential oils from T. daenensis Celak. subsp. daenensis displayed significant inhibitory effects on all three Aspergillus species, with minimum inhibitory concentration (MIC) ranging from 575 to 707 ppm and half maximal inhibitory concentration (IC50) ranging from 237 to 280 ppm. These findings reaffirm the potent antifungal activity of the essential oils. Additionally, the essential oil exhibited free radical scavenging activity, with an EC50 value of 37.1 μg/ml. Overall, the essential oil from T. daenensis Celak. subsp. daenensis demonstrates superior characteristics compared to similar plants and synthetic antibiotics, indicating its promising potential as a natural alternative.

“…These results suggest that the mating type MATD-2 dominates on maize kernels in Serbia. On the other hand in Iran, isolates from maize mainly belonged to MATD-1, while the isolates from rice roots belonged to MATD-2 (Alizadeh et al, 2010). According to these authors, isolates originating from the roots of sugarcane were equally represented with MATD-1 and MATD-2, while all isolates from the roots of onion belonged to MATD-1.…”

Genetic (mating population and vegetative compatibility), pathogenic and toxigenic variability of F. proliferatum isolated from maize kernels originating from different localities in Serbia were studied. Investigated isolates of F. proliferatum were fertile and most of them (8/13) belonged to the mating type MATD-2. Based on the complementary test isolates, F. proliferatum were grouped into 11 vegetative compatibility groups (VCGs) and two isolates were self-incompatible. All tested field isolates of F. proliferatum and nit mutants were pathogenic and most expressed medium pathogenicity. Field isolates of F. proliferatum showed a higher potential for biosynthesis of FB 1 (up to 1,246.00 µg g-1) in relation to their nit1 (up to 53.41 µg g-1) and NitM mutants (up to 56.17 µg g-1). Based on genetic, pathogenic and toxigenic properties of 13 isolates of F. proliferatum, relatively high variability of this fungus originated from maize grain was found.
