“…It has long been recognized that some volatiles have antimicrobial properties (Nychas, 1995). Besides antibacterial properties, they also have been shown to exhibit antiviral and antimycotic properties (Bishop, 1995;Mari et al, 2003). In addition to this anti-microbial activity, anti-oxidant activity is another main characteristic of plant secondary metabolites, mainly from phenolic compounds (Sanchez-Moreno, 1999).…”

Low-molecular-weight secondary metabolites from plants play an important role in reproductive processes and in the defense against environmental stresses or pathogens. In the present study, we isolated various volatiles and phenolic compounds from white Rosa rugosa flowers, and evaluated the pharmaceutical activities of these natural products in addition to their ability to increase survival in response to environmental stress and pathogen invasion. The DPPH and hydroxyl radical-mediated oxidation assay revealed that the white rose flower extract (WRFE) strongly scavenged free radicals in a dose dependent manner. Moreover, WRFE inhibited the growth of E. coli and fatally attacked those cells at higher concentration (>0.5 mg/mL). FITC-conjugated Annexin V stain provided further evidence that WRFE had strong antimicrobial activity, which may have resulted from a cooperative synergism between volatiles (e.g. 1-butanol, dodecyl acrylate and cyclododecane) and phenolic compounds (e.g. gallic acid) retained in WRFE. In conclusion, secondary metabolites from white rose flower hold promise as a potential natural source for antimicrobial and non-chemical based antioxidant agents.

“…Quality loss is a normal process during storage, but the level of degradation depends on storage conditions and the technologies used (Hulea, et al, 1982;Mari, et al, 2003). Currently, arrays of chemical treatments are used to preserve fresh produce.…”

Grape as a perishable fruit is susceptible to fungal infection especially Botrytis cinerea, as an agent of gray mold, and berry dehydration. There are limitations in use of synthetic chemical compounds to control postharvest losses in grape and other fruits. The aim of this study was the evaluation of non-chemical and safe methods for this purpose. Therefore, ozone soluted at 0.3 ppm concentration with three treatment times (5, 10 and 15 min), in water was applied on 'Bidaneh Qermez' grape cultivar. Qualitative characteristics (decay, vitamin C, reducing sugars, weight loss, berry abscission, dehydration, cracking and sensory analyses) were evaluated. The results showed that treated fruits with ozone had lower decay percentage, weight loss, berry dehydration, abscission, cracking and higher reducing sugars and storage quality compared to controls. As a general result, ozone treatment caused lower decay incident and longer storability.

“…In in vitro and in vivo studies, Pseudomonas, Rahnella and Serratia can lessen late blight symptoms by a combination of antibiosis and induced resistance against P. infestans (Daayf et al, 2003). Essential oils: Mari et al (2003) gave the information about the use of natural compounds derived from plants to control late blight in potato crop. The use of biological compounds extracted from plants may be an alternative to conventionally used fungicides to control phyto-pathogenic fungi, due to their being bio-active chemicals such as flavonoids, phenols, tannins, alkaloids, quinons, saponins and sterols (Burt, 2004).…”

Late blight of potato caused by fungus Phytophthora infestans responsible for Irish famine in the year 1845, is one of the most dramatic episode caused by plant pathogen in human history. One million people died due to famine in Ireland. So eco-friendly management of potato late blight disease is a necessary goal to be accomplished. During last many years, management strategies solely relied upon the application of fungicides due to rapid development of late blight epidemics. However, indiscriminate use of fungicide posesses a serious threat to the environment and human health. It is also responsible for built up of resistance in the pathogen and have adverse effect on beneficial organisms such as nitrogen fixers, resident antagonism and mycorrhizal fungi. So to minimize the fungicide use, eco-friendly means for late blight management are required on a priority basis. In recent years, significant changes in isolates of late blight fungus have been recorded including changes in aggressiveness to the crop also. Since, late blight is a community disease so, effective eco-friendly management must be adopted by the all producers, farmers, gardeners and growers with the help of government agencies, extension specialist and crop consultants etc. The strategy to control late blight is the prevention of establishment of Phytophthora infestans in potato crop. In this context, disease management by cultural practices is the first line of defense while forecasting system, physiological strategies, biological control, host plant resistance and bio-technological approach are essential for efficient, effective and eco-friendly management of late blight of potato.
