  Problem statement: Increasing public concern over the level of pesticide residues in food especially fresh produce has built up adequate pressure for scientists to look for less hazardous and environmentally safer compounds for controlling post harvest diseases. Essential oils as registered food grade materials have the potential to be applied as alternative anti-fungal treatments for fresh fruits and vegetables. Approach: We present in this study, the identification of the essential oils with antifungal activity from some medicinal plants of Iran (nettle (Urtica dioica L.), thyme (Thymus vulgaris L.), eucalyptus (Eucalyptus spp.), Rue (Ruta graveolens L.) and common yarrow (Achillea millefolium L.)), and their potential application as "generally regarded as safe" antifungal compounds against Alternaria alternate on tomato as a model pathosystem. Results: Both the nettle and the thyme oils exhibited antifungal activity against A. alternata. The thyme oil exhibited a lower degree of inhibition 68.5 and 74.8% at 1500 and 2000 ppm, respectively. Spore germination and germ tube elongation of the pathogens in potato dextrose broth was strongly reduced in the presence of 1500 ppm of the nettle oil. The same concentration of this oil reduced the percentage of decayed tomatoes. The experiments on reducing the development of natural tomato rot gave similar results. Conclusions: Application of essential oils for postharvest disease control of fresh produce, as a novel emerging alternative to hazardous anti-fungal treatments will allow a safer and environmentally more acceptable management of postharvest diseases.

  In this study, phytotoxicity of rice hull extracts (Oryza sativa L.) on wild oat (Avena ludoviciana Durieu) was investigated. Hull extracts from 13 cultivated rice cultivars (Oryza sativa L.) were used to determine their allelopathic potential on seed germination and seedling growth of wild oat (Avena ludoviciana Durieu). The allelopathic effects of water hull extracts from selected cultivars were investigated. In the screening the Red anbarbo extract inhibited germination 24% very closely fallowed Daniyal is 27%. Seedling growth bioassays demonstrated that the wild-oat (Avena ludoviciana Durieu) responded differently to the allelopathic potential of rice. For wild-oat (Avena ludoviciana Durieu) shoot length and germination were more depressed than root length. Some hulls extracts including Champa, Sahel almost didn’t affect root length. The greatest total seedling length inhibition was from the Daniyal extracts. Extract of rice hulls significantly reduced roots length of wild oat. Extracts of Daniyal reduced root length of wild oat by 2.19 cm. This cultivar have the highest inhibitory on root length of wild oat. These results suggest that rice hull extracts may be a source of natural herbicide. There may be genetic differences among rice cultivars for allelopathic potential on Wild-oat. The breeding of rice cultivars with greater allelopathic potential may be possible.

  Anti-mycotic activity of the ethanol extracts from Nettle (Urtica dioica L.), Colocynth (Citrullus colocynthis L. Schrad), Konar (Ziziphus spina-christi L.) and Oleander (Nerium oleander L.) floral parts were screened in vitro against four important plant pathogenic fungi viz., Alternaria alternate, Fusarium oxysporum, Fusarium solani and Rizoctonia solani using agar dilution bioassay. Extracts showed antifungal activity against all the tested fungi. Among the plants, Nettle and Colocynth were the most effective against A. alternate and R. solani while Oleander possesses the best inhibition on F. oxysporum and F. solani. Konar was the most effective extract by reducing the growth of Rizoctonia solani than other fungi. These results showed that extracts could be considered suitable alternatives to chemical additives for the control of fungal diseases in plants.
