ABSTRACTThe use of natural substances for pest control in agriculture is, economically, a viable option and has benefits for both the humanbeing and the environment, due to its low persistence and toxicity. Thus, this trial aimed on determining the insecticidal potential of the extracts and essential oils of fennel (Foeniculum vulgare Mill.), anise (Pimpinella anisum L.) and clove (Caryophillus aromaticus L.) to control Brevicoryne brassicae L. in kale (Brassica oleracea var. acephala DC.). The treatments were: fennel, anise, cloves extracts at 10%; fennel, anise, cloves oils at 1% and control with distilled water. The mortality tests were carried out with aphids in laboratory, with three replications, after 1, 12, 24, 48 and 72 hours. During laboratory trials , it was found out that fennel oil at 1% showed the best rate of mortality on aphid nymphs (70% at 72 h), followed by clove extract at 10% with 37% mortality. Tests in pots were only carried out only with cloves extracts at 10% and fennel oil at 1% treatment, in which such efficiency was alsoindicated on aphid nymphs.

Anise (Pimpinella anisum L.) is an important medicinal spice plant that belongs to the family Apiaceae. Anise seeds are rich in essential oils and this is a reason why anise production in Serbia has increased over the last decade. During a routine health inspection on anise seeds collected from three localities in the province of Vojvodina (Mošorin, Veliki Radinci and Ostojićevo) during 2012 and 2013, it was found out that Fusarium spp. were a commonly observed fungi. The presence of Fusarium fungion the seed samples ranged from 3.75-13.75%. The aim of this study was to isolate and identify the strains of Fusarium species present on anise seed samples as it is necessary that commercially used anise seeds are completely free of Fusarium. Based on morphological, microscopic characteristics and a molecular identification by sequencing of TEF gene, the presence of the following species was confirmed on the anise seeds: F. tricinctum, F. proliferatum, F. equiseti, F. oxysporum, F. sporotrichoides, F. incarnatum and F. verticillioides. According to our knowledge and research, this is the first report of F. tricinctum and F. sporotrichoides as pathogens on anise seeds in the world. All seven isolates of Fusarium species are pathogenic to the anise seedlings, while the most virulent species were F. oxysporum, F. tricinctum and F. incarnatum.

AbstractPhytopathogenic fungi have been responsible for considerable economic losses in vineyards, and therefore, more attention should be paid to the development and implementation of preventative treatment that is environmentally friendly. The aim of this study was to evaluate the antifungal activity of ten essential oils (EOs) (viz. Lavandula angustifolia Mill., Carum carvi L., Pinus mugo var. pumilio, Mentha piperita L., Foeniculum vulgare L., Pinus sylvestris L., Satureja hortensis L., Origanum vulgare L., Pimpinella anisum L. and Rosmarinus officinalis L.). For the antifungal activity evaluation against Penicillium brevicompactum, P. citrinum, P. crustosum, P. expansum, P. funiculosum, P. glabrum, P. chrysogenum, P. oxalicum, P. polonicum and Talaromyces purpurogenus a disc diffusion method was used. The ten EOs exhibited different antifungal properties. Three tested EOs (Carum carvi L., Satureja hortensis L. and Pimpinella anisum L.) at concentrations of 0.75, 0.50, 0.25 and 0.125 µL/mL showed antifungal activity, inhibiting the mycelial growth. The Origanum vulgare L. EOs exhibited a lower level of inhibition. Overall, Lavandula angustifolia Mill., Pinus mugo var. pumilio, Mentha piperita L., Foeniculum vulgare L., Pinus sylvestris L., Satureja hortensis L., Pimpinella anisum L. and Rosmarinus officinalis L. were effective as fungicidal agents but their efficiency varied between the strains of fungi. Carum carvi L. showed strong antifungal activity against all tested strains at both full strength and reduced concentrations. These EOs could be considered as potential sources of antifungal compounds for treating plant fungal diseases.
