Fungicides have been extensively used to control fungal diseases that affect several crops including ornamental crops. However, concerns have arisen due to a development of fungicide resistance and increasing incidences of fungicide toxicity effects on nontarget organisms. As zinc oxide nanoparticles (ZnO NPs) have demonstrated effective antimicrobial activity, this study is therefore aimed at synthesizing ZnO NPs from banana peels using a green chemistry method in a large scale and determines their physical properties including their inhibitory effects against a plant pathogen fungus causing anthracnose in orchids, Colletotrichum sp. Results from X-ray diffraction and scanning electron microscope indicated that the synthesized ZnO NPs were obtained without other crystalline impurities, and they were spherical in shape with the average diameter of 256 ± 40 nm , respectively. The absorption peak was found to be centered at ~370 nm with the optical band gap value approximately 2.8 eV. Fourier transform infrared spectroscopy analysis confirmed the presence of several functional groups on synthesized ZnO NPs. The total amount of synthesized ZnO NPs was obtained about 170 g for a synthesis reaction. By performing the antifungal activity assay, high doses of green synthesized ZnO NPs significantly inhibited growth of isolated Colletotrichum sp. (KUFC 021) on culture plates. Under greenhouse conditions, high doses of synthesized ZnO NPs also significantly reduced anthracnose symptoms on inoculated orchid leaves with the Colletotrichum sp. (KUFC 021).

“…On the other hand, the identification of host plants of pathogens is sometimes difficult. For example, it was shown that ornamental plants like orchids [ 15 , 17 , 18 , 19 , 20 ], agricultural plants [ 21 ], and woody plants [ 22 , 23 ] can be infected by Fusarium ssp., causing molds and leaf spots. Interestingly, Fusarium ssp.…”

Microeukaryotic Communities on the Fruit of Gardenia thunbergia Thunb. with a Focus on Pathogenic Fungi

Woody fruit which stay on ornamental plants for a long time may present a risk of infection to other organisms due to the presence of pathogens on their surface. We compared the microbe communities on the fruit surfaces of garden ornamental Gardenia thunbergia Thunb. with those on other surfaces in the study region. As Gardenia fruit contain antifungal substances, the focus of this study was on the fungal communities that exist thereon. We used Illumina sequencing to identify Amplicon Sequence Variants (ASV) of the internal transcribed spacer 2 (ITS2) of the ribosomal RNA. The microbial communities of the Gardenia fruit are distinct from the communities from the surrounding environments, indicating a specialized microhabitat. We employed clustering methods to position unidentified ASVs relative to known ASVs. We identified a total of 56 ASVs representing high risk fungal species as putative plant pathogens exclusively found on the fruit of Gardenia. Additionally, we found several ASVs representing putative animal or human pathogens. Those pathogens were distributed over distinct fungi clades. The infection risk of the high diversity of putative pathogens represented on the Gardenia fruit needs to be elucidated in further investigations.
