“…Although chemical fungicides are often used as the first defence against the fungal diseases. While the global contemporary trend has transferred to safer and environmental friendly methods to control these microbes and fungi [ 18 ]. Therefore, it is much significant to search for natural and potential antimicrobial agents to control the root-rot of P. notoginseng .…”

Replanting obstacles of Panax notoginseng caused by complex factors, including pathogens, have received great attention. In this study, essential oils (EOs) from either Alpinia officinarum Hance or Amomum tsao-ko (Zingiberaceae) were found to inhibit the growth of P. notoginseng-associated pathogenic fungi in vitro. Subsequent GC-MS analysis revealed the chemical profiles of two plant derived EOs. Linalool and eucalyptol were found to be abundant in the EOs and tested for their antifungal activities. In addition, the synergistic effects of A. tsao-ko EOs and hymexazol were also examined. These findings suggested that Zingiberaceae EOs might be a good source for developing new green natural pesticides fighting against root-rot of P. notoginseng.

Metal nanoparticles used as antifungals have increased the occurrence of fungal–metal interactions. However, there is a lack of knowledge about how these interactions cause genomic and physiological changes, which can produce fungal superbugs. Despite interest in these interactions, there is limited understanding of resistance mechanisms in most fungi studied until now. We highlight the current knowledge of fungal homeostasis of zinc, copper, iron, manganese, and silver to comprehensively examine associated mechanisms of resistance. Such mechanisms have been widely studied in Saccharomyces cerevisiae, but limited reports exist in filamentous fungi, though they are frequently the subject of nanoparticle biosynthesis and targets of antifungal metals. In most cases, microarray analyses uncovered resistance mechanisms as a response to metal exposure. In yeast, metal resistance is mainly due to the down-regulation of metal ion importers, utilization of metallothionein and metallothionein-like structures, and ion sequestration to the vacuole. In contrast, metal resistance in filamentous fungi heavily relies upon cellular ion export. However, there are instances of resistance that utilized vacuole sequestration, ion metallothionein, and chelator binding, deleting a metal ion importer, and ion storage in hyphal cell walls. In general, resistance to zinc, copper, iron, and manganese is extensively reported in yeast and partially known in filamentous fungi; and silver resistance lacks comprehensive understanding in both.

In vitro antifungal evaluation of L-ascorbic acid (vitamin C) towards Monilia frucigena, Alternaria solani and Venturia inaequalis

In vitro antifungal tests with one of the most popular medical substance in the world – L – ascorbic acid, widely known as vitamin C, were conducted with three of the most spread plant pathogens in Bulgaria: Monilia frucigena, Alternaria solani and Venturia inaequalis in order to evaluate the direct antifungal action of the acid used in agriculture as ISR promoter (phytovaccine). The expression of pesticide action of ISR promoters is not unusual unlike the vaccines for the animals and humans. Conducted tests shows the strong antifungal activity of L – ascorbic acid towards mycelium and conidiospores of Alternaria solani and Venturia inaequalis and a very weak antifungal action towards Monilia frucigena which means that vitamin C can be used as a direct fungicide agent and phytovaccine in the pest management simultaneously. The substance has excellent water solubility which make is very appropriate for formulation as a plant protection product.
