“…Paster et al [35] demonstrated antifungal activity of oregano essential oil on the mycelium and spores of A. niger, A. flavus and A.ochraceus. The results of this study agree with those of other authors, including Bouchra et al [7] and Baratta et al [36] who also showed that the antifungal activity of oregano essential oil on A. niger is much stronger than that of sage. Martos [37] found that oregano essential oil showed the highest inhibition of mold growth, followed by clove and thyme.…”

“…Recently, medicinal plants and their extracts have gained importance as potential antimicrobial agents because they are generally assumed to be more acceptable and less hazardous than synthetic compounds [2]. Numerous studies have documented the antifungal properties of plant products [5][6][7][8][9][10][11][12][13]. In in vivo studies, emulsions of oils of thyme and oregano at 5000 ppm and 10000 ppm as dip treatments reduced disease development in tomatoes inoculated with Botrtytis cinerea and Alternaria arborescens [14].…”

Ethanolic extracts of tarragon (Artemisia dracunculus), rosemary (Rosemarinus officinalis L) and thyme (Thymus vulgaris L.) and the essential oil of oregano (Origanum vulgare L.) were tested against many fungi including A.niger, A.flavus, Penicillium spp., Rhizopus spp. and fusarium spp. Oregano essential oil showed a very strong antifungal activity against Fuazarium spp. (MIC: 0.8 mg/ml), A.niger (MIC: <1 mg/ml) and Penicillium spp. (MIC: 4.5 mg/ml) whereas other fungi showed more resistant. The results showed that Rhizopus spp. was the most sensitive fungus to the plant extracts whereas rosemary was the most effective plant. Application of essential oils or ethanolic rosemary extract with different concentrations (100, 500, 1000, 1500, 2000 ppm) and refrigeration storage (at either 5 or 25°C) for postharvest spoilage control of tomatoes for 4 weeks showed that the combination of two treatments (refrigeration with either oregano essential oil or rosemary extract) was more effective to keep quality of tomatoes.

“…In addition, the microscopic observations of the fungal isolates treated by the extracts of R. officinalis revealed structural modifications leading to the lysis of the mycelium and, the digestion of sporangia contents, there by confirming the fungicidal effect of the plant extract. It is the toxic effect of its components on the structure and the physiology of the cellular membrane that is responsible for the antifungal effect [24,25]. In this sense, Omidbeygi et al [26] suggested that the components of essential oil and extracts of plants cross cell wall and interact with enzymes and proteins, it is the production of a flux of protons towards the exterior cell which incites cellular changes and after all, the death of the microorganism.…”

The fungus Phytophthora infestans is known to develop resistance against the metalaxyl (fungicide), commonly used in the control of potato mildew disease. There is therefore urgent need to explore the potentials of alternative fungicides which are potent, affordable, readily available, easy to prepare and environment friendly. The study was carried out to test the fungicidal potential of aqueous extracts of Rosmarinusofficinalis (Rosemary), in vitro and in vivo on two isolates of P. infestans collected from two potato producing Algerian areas: Bourkika (Tipaza City) and El Abbadia (Aindefla City). Various concentrations of crude extracts of Rosmarinus officinalis applied by direct contact in the following dilutions: 5%, 10% and 20% on medium with pea-agar (PPA), allowed the inhibition of mycelial growth of P. infestans isolates. The observed rates of inhibition exceeded 85% and the inhibitive minimal concentration (CMI) was 5%. Parallel structural modifications, caused by mycelial lyses, as well as the deformation or, and the digestion of the contents of sporangia affected the morphology of both strains from the lowest concentration. The sporulation and the germination were inhibited by this aqueous extract (100%). Also, the absence of resumption of mycelial growth on medium PPA and absence of the mildew symptoms on detached Spunta potato leaves confirmed the fungicidal effect of the Rosemary aqueous extract. This also translated in vivo as significant reduction of the disease was observed. Disease reduction was recorded for the preventive application modes by spraying with the crude aqueous extract (86.2%) and by watering, while for the curative mode with crude extract (81%). On the other hand, Spunta variety was more marked for preventive mode by watering (85%) and the curative one (90%) also, A2 isolate was more inhibited for the application of R. officinalis aqueous extract by curative (83%), spraying mode (86%) and watering modes. Besides, treatments made in preventive modes by spraying and watering showed a total inhibition of the sporulation (100%), exceeding 85% in Spunta variety and 96% for A1 isolate was observed in the curative mode of application. This study thus confirms the antifungal potential of aqueous extract of Rosmarinus officinalis on P. infestans isolates. It is thus recommended for use as bio-fungicide in the management of potato mildew disease.

Objective: Essential oils with antimicrobial and antioxidant activities have gained importance. This study was conducted to investigate the genotoxic potential of the essential oil of Origanum compactum.Methods: Micronucleus test and proliferation index (PI) were used to evaluate the genotoxic effect of the essential oil of O. compactum on human lymphocytes. Results:The results demonstrated that the PI values were influenced by the tested essential oil. An increase in concentration of essential oil also caused the appearance of micronuclei. Conclusion:The results of the present work suggest that O. compactum essential oil exhibited genotoxic activity at higher concentration. Further studies are necessary to confirm these findings.
