“…Additionally, compound 2 isolated from Rhizoctonia solani could inhibit seed germination that have also been reported ( D’Silva and Herrett, 1971 ). Previous report suggested that furan organic compounds are of bacteriostatic and fungistatic effect on diverse microorganisms ( Vijayakumar and Thirunanasambandham, 2021 ; Steglińska et al, 2022 ). Besides, previous studies had confirmed that microbes could produce different secondary metabolites under different culture conditions ( D’Silva and Herrett, 1971 ; Portela et al, 2022 ).…”

Five furanoids including a new analog (S)-1,4-di(furan-2-yl)-2-hydroxybutane-1,4-dione (1) together with four known ones, rhizosolaniol (2), 5-hydroxymethylfurfural (3), 2-furoic acid (4) and (2-furyl) oxoacetamide (5), were isolated from the fungal strain Ceratobasidium sp. (GS2) inducing seed germination of the endangered medicinal plant Gymnadenia conopsea of Orchidaceae. The structure of new furanoid 1 was determined mainly based on HR-ESI-MS and NMR spectral data. Modified Mosher’s reactions were used to establish the stereochemistry of the hydroxyl group in 1, which was not stable in Mosher’s reagents and transformed into four analogs 6–9. These degraded products (6–9) were elucidated based on UPLC-Q-TOF-MS/MS analysis, and compound 8 was further isolated from the degraded mixture and its structure was characterized through NMR experiments. Therefore, the absolute configuration of compound 1 was determined by electronic circular dichroism combined with quantum-chemical calculations adopting time-dependent density functional theory. Compounds (1–5), and 8 showed weak antioxidant activities, and compounds (2–4) displayed phytotoxicity on punctured detached green foxtail leaves. In addition, compounds 3 and 4 strongly showed inhibition activities on the seed germination of G. conopsea. This was the first chemical investigation of the symbiotic fungus of G. conopsea.

“…In this work, we evaluated the effect of aqueous garlic extract as a plant biopesticide against mycotoxin-producing fungi that infect potatoes. Several works confirmed the antifungal activity of garlic extracts on Alternaria , Rhizoctonia , Fusarium , Colletotrichum , and Phoma fungi [ 19 , 34 , 35 , 36 ]. The antimicrobial activity of garlic extracts is linked to the production of organosulphur compounds such as allicin, ajoenes, diallyl disulphide, methyl allyl disulphide, and others [ 37 ].…”

“…This can be achieved through various biological approaches, e.g., the use of microorganisms and their metabolites, plant extracts, or combined methods with certain synthetic compounds [ 8 ]. In our previous research, we described the inhibition of phytopathogen growth using three biological control agents: lactic acid bacteria [ 17 ], yeast Metschnikowia pulcherrima [ 18 ], and garlic water extract [ 19 ].…”

The potato is a crop of global importance for the food industry. This is why effective protection against pathogens is so important. Fungi as potato pathogens are responsible for plant diseases and a significant reduction in yields, as well as for the formation of mycotoxins. This study focuses on the effect of three natural biocides, yeast Metschnikowia pulcherrima, lactic acid bacteria Lactiplantibacillus plantarum, and aqueous garlic extract, on the improvement of the physiology of planted potato tubers and the reduction in mycotoxin formation. The secondary metabolites produced by the fungal pathogens of genera Fusarium, Alternaria, Colletotrichum, Rhizoctonia, and Phoma in the presence of these biocontrol agents were compared to profiles obtained from contaminated potatoes. Analysis of liquid chromatography coupled with tandem mass spectrometry data showed the presence of 68 secondary metabolites, including the mycotoxins: alternariol, alternariol methyl ether, altertoxin-I, aurofusarin, beauvericin, diacetoxyscirpenol, enniatin B, and sterigmatocystin. The studies showed that the applied biocontrol agents had a positive effect on the physiological parameters of potatoes (including root growth, stem growth, gas exchange, and chlorophyll content index) and on the reduction in the production of mycotoxins and other secondary metabolites by Fusarium, Alternaria, and Phoma.

“…On the other hand, the decrease in the number of active substances of fungicides (including bactericides) allowed for use in crop production, concern for the environment, and the development of organic crop production is leading to the development of alternative environmentally friendly pest control systems to combat crop diseases [ 24 ]. The use of natural compounds such as essential oils and plant extracts in plant protection against diseases is promising [ 25 , 26 ].…”

The bacteria Pseudomonas savastanoi pv. glycinea (Coerper, 1919; Gardan et al., 1992) (Psg) and Curtobacterium flaccumfaciens pv. flaccumfaciens (Hedges 1922) (Cff) are harmful pathogens of soybean (Glycine max). Presently, there are several strategies to control these bacteria, and the usage of environmentally friendly approaches is encouraged. In this work, purified essential oils (EOs) from 19 plant species and total aqueous and ethanolic plant extracts (PEs) from 19 plant species were tested in vitro to observe their antimicrobial activity against Psg and Cff (by agar diffusion and broth microdilution method). Tested EOs and PEs produced significant bacterial growth inhibition with technologically acceptable MIC and MBC values. Non-phytotoxic concentrations for Chinese cinnamon and Oregano essential oils and leather bergenia ethanolic extract, which previously showed the lowest MBC values, were determined. Testing of these substances with artificial infection of soybean plants has shown that the essential oils of Chinese cinnamon and oregano have the maximum efficiency against Psg and Cff. Treatment of leaves and seeds previously infected with phytopathogens with these essential oils showed that the biological effectiveness of leaf treatments was 80.6–77.5% and 86.9–54.6%, respectively, for Psg and Cff. GC-MS and GC-FID analyzes showed that the major compounds were 5-Methyl-3-methylenedihydro-2(3H)-furanone (20.32%) in leather bergenia ethanolic extract, cinnamaldehyde (84.25%) in Chinese cinnamon essential oil and carvacrol (62.32%) in oregano essential oil.
