Anthracnose symptoms consisting of necrotic spots on the leaves, twigs and branches were observed on mango trees of cv. Kensington Pride in orchards located in the countryside of Palermo and Milazzo (southern Italy). Based on morphological observations and phylogenetic analysis of the β-tubulin (benA) and histone H3 (HIS3) genes, three Colletotrichum species were identified and recovered from diseased plants, i.e. C. karstii (nine isolates), C. kahawae subsp. ciggaro (six isolates) and C. gloeosporioides (six isolates). Following artificial inoculation, all species induced symptoms on the leaves and fruits of cv. Kensington Pride. To our knowledge, this is the first report of mango anthracnose caused by C. karstii, C. kahawae subsp. ciggaro and C. gloeosporioides in Italy. © 2015, Journal of Plant Pathology.

An independent evaluation of Silva Mediterranea, carried out at the request of members, confirmed the need for such a forum to ensure international dialogue on forests in the Mediterranean. The specificities of the mediterranean region and the need for appropriate responses are recurrent themes in the history of the Committee. The Committee, which was for many years the main regional cooperation body for Mediterranean forests, including on research questions, has gone through both dormant and more dynamic phases, as has been the case in recent years. Conducted by a panel set up in such a way as to ensure institutional memory at the same time as an objective vision, in order to ensure the required neutrality, the evaluation process was conducted throughout 2013. The panel encourages stronger ownership and mobilization of member states around a common vision and the identification of priority areas among the strategic lines and/or recommendations of the Strategic Framework on Mediterranean Forests (SFMF).

Fruits | Year: 2015

Introduction. Drosophila suzukii Matsumura (Spotted Wing Drosophila, SWD) is a pest that has been indicated as a major threat to European and Mediterranean fruit production. Its finding in Southern Italy offers interesting data to elaborate an efficient and sustainable control strategy. Materials and methods. The fly was collected during the "overhead"survey of an IAMB organic table grape vineyard by apple vinegar/wine/brown sugar bottle traps placed in and around the field. Once the presence of this pest was confirmed, traps were also hung on different host plants surrounding the vineyard, namely fig (Ficus carica L.), jujube (Ziziphus jujuba Mill.), pomegranate (Punica granatum L.), wild bramble (Rubus fruticosus L.) and rough bindweed (Smilax aspera L.). Collected Drosophila adults were identified via morphological parameters by comparison with published descriptions and drawings. The SWD adult population was monitored per month throughout the year and related to the average values of the temperature (°C) and minimum relative humidity (mRH%). The survey was carried out from September 2012 to August 2013. Results and discussion. We report the finding of Drosophila suzukii in Southern Italy, Apulia Region, and its population dynamics throughout the year in the area. In addition to D. suzukii, D. melanogaster (Meigen), D. simulans (Sturtevant) and similar species were also scored. The D. suzukii dynamics appeared to be strictly correlated with the temperature and relative humidity changes throughout the year, with a great summer population decrease. This behaviour is quite different from that of other indigenous drosophilas, both pest and non-pest. Conclusion. D. suzukii has, at present, a prominent pest status and may represent a key pest of soft fruit orchards in the South-Eastern part of Italy and, namely, in Apulia. However, further investigation on the marked decrease in the SWD summer population is needed to support effective pest control strategies, which include baited-lure mass trapping in Mediterranean and other warm climate areas. Such strategies should also take into consideration pest reservoirs such as secondary and semi-wild fruit species bred in the areas tested. © Cirad/EDP Sciences 2015.

Eggplant peels were used to evaluate glycerol and ethanol for their ability to recover polyphenolic antioxidants. The evaluation was based on optimisation by a Box-Behnken experimental design and kinetics. The results showed that extraction with water/ethanol and water/glycerol mixtures, under optimised conditions, afforded virtually equal yield in total polyphenols, which was 13.40 and 13.51 mg caffeic acid equivalents per g dry weight, respectively. The extraction kinetics revealed that diffusion of phenolics in water/glycerol mixtures was slower (0.85 × 10−12 m2 s−1) compared with the one attained with water/ethanol (2.23 × 10−12 m2 s−1), yet the ability of both systems to recover essentially the same levels of total polyphenols was confirmed. The determination of total chlorogenates, total flavonoids and total pigments indicated that water/glycerol might be a more effective solvent system, but controversies were observed with regard to the antiradical activity and reducing power. The analytical polyphenolic profile of both extracts was dominated by chlorogenic acid and no major differences were recorded, a finding indicating that none of the solvent systems displayed selectivity. The results suggested that glycerol may be an ideal candidate for use in eco-friendly extraction processes. © 2016, Springer International Publishing Switzerland.

The aim of this study was to evaluate the effects of different organic fertility sources on organic broccoli (Brassica oleracea var. italica) growth and yield, and on soil properties. The fertilization was designed to supply the crop with about 100 kg ha-1 of N using two amendments: a municipal solid wastes-based compost (CC), and a manure based compost (CB). The former was used alone (T1), in combination with its own water extract (CT) in fertigation (T2), and in combination to CT applied in fertigation and as foliar spray (T3). Other treatments resulted from the application of (i) CC and CB (T4); (ii) CB alone (T5); and (iii) the exhausted compost (EX) resulting from the extraction of CT (T6). Unamended plots were used as control (T7). Selected soil properties were determined at the beginning and at the end of the trial in order to estimate the effects of the various treatments on these parameters. The best yields were obtained with T4 and T5 (16.95 and 18.46 t ha-1, respectively). The application of CC alone (T1) showed slightly better growing parameters in comparison to its application in combination to CT (T2 and T3), even though the yields were not significantly different from each other. T6 showed the lowest yield of broccoli (7.03 t ha-1) among the treatments, superior only to the unfertilized control (5.38 t ha-1, T7). The different fertilizations showed a general soil enrichment of available phosphorous and organic matter, even if the latter could be only transitory. Finally, the high production costs and the low yields obtained apparently dissuade the use of compost tea and exhausted compost for the fertilization of broccoli crop. © 2015 Copyright © Taylor and Francis Group, LLC.

Melia azedarach fruit extracts have recently raised a substantial interest for their use in crop protection against phytoparasitic nematodes. The effect of M. azedarach on the root-knot nematode Meloidogyne incognita on cucumber, as well as the effect on the plant deference mechanism, is reported herein. Crushed fruits of M. azedarach, tested in the soil at the rates of 30 and 60 g kg -1, exhibited nematicidal activity similar to the one of fenamiphos (0.02 g a.i. kg -1) in terms of nematode population in roots and soil as well as reproduction rate. M. azedarach water extracts, rich in aldehydes, alcohols and carboxylic acids, showed nematicidal activity against M. incognita. Moreover, all M. azedarach treatments decreased the activities of catalase (CAT) and peroxidase (POX) involved in host H 2O 2 detoxification. Soil application of M. azedarach fruits could be favourably considered in the control of M. incognita on cucumber in a sustainable agriculture, since they act directly as nematicidals. Furthermore, M. azedarach elicits plant defence and helps the host to fight the nematodes infestation in an indirect way. © 2012 Elsevier Ltd.

The rising popularity of compost tea as fertilizer or foliar spray against pathogens has encouraged many researchers to evaluate its performance without standardizing its quality, so obtaining inconsistent and controversial results. The fertilizing and pesticide-like effects of compost tea are due to its chemical and microbiological properties. Therefore, this study aimed to identify the best combination of the compost tea extraction parameters for exalting both chemical and microbiological features. A factorial design was adopted to evaluate the effects of compost/water ratio, extraction time, storage duration and storage temperature in different combination on physical, chemical and microbiological characteristics of compost tea, and the results were elaborated through different statistical analyses. Compost tea nutrients and microorganisms were influenced by compost/water ratio and extraction time. In addition, the storage duration affected the microbial populations, whereas the storage temperature influenced only the fungal population of compost tea. Results suggested that the best combination of the studied parameters was: 1:2.5 compost/water ratio, 2. days of extraction time and the compost tea should be utilized immediately after the extraction, since the storage reduced the microbial populations. © 2016 Elsevier Ltd.

The frequency and intensity of drought, extreme events and high wind velocities in South Africa are expected to increase in the next century as a result of the changing climate. The National Water Resource Strategy 2 (NWRS2) has set out the general and strategic directions for water resources management in the country for the next 20 years. However, the strategy does not draw a framework tailored specifically for agricultural use, with specific measures and goals. Therefore, to reach sustainability of water in agriculture, four major strategic goals are suggested, on which research institutions can focus and promote through good governance. The strategy emphasises: (1) crop research to find new droughtand heat- tolerant and resistant breeds and varieties; (2) intensified research in agricultural practices; (3) increasing the efficiency of water use within agriculture; and (4) integrating all these strategic goals within a sustainable research framework. Finally, the research calls for rapid action and implementation. Significance: • The framework is proposed for stakeholders and policymakers in higher education, agriculture and resources management in South Africa for new research horizons at national level to improve overall agricultural sustainability by 2030 as stipulated by the Millennium Development Goals. © 2016.

The effects of a previously selected entomopathogenic fungus, Beauveria bassiana AL1 strain, and the B. bassiana based mycoinsecticide Naturalis (ATCC 74040 Beauveria bassiana strain) were evaluated on the system Ceratitis capitata - Psyttalia concolor in laboratory assays. First, the entomopathogenic fungal strains were tested for their virulence against 2, 4, and 6-days old puparia of C. capitata. Subsequently, P. concolor emergence from C. capitata puparia treated or not with the fungal strains was evaluated at three different time points (2, 4 and 6 days) from the parasitization and the following pupation. Results showed that the entomopathogenic fungal applications affected the medfly survival. The effect of fungal treatments was higher on 2-day puparia (49.16 and 51.33% of mycosed puparia for ATCC 74040 and AL1 strain respectively) while the rate of mycoses was lower and ranged between 39 and 27.16% when fungal treatments were performed on 4 and 6-day puparia. Furthermore, fungal treatments affected the P. concolor emergence (c.a. 80% in the untreated control) particularly when applied 2 days after the parasitization and the C. capitata pupation (43.16 and 47.83% for the ATCC 74040 and the AL1 strains respectively), while when treatments were performed on older puparia, the P.concolor emergence ranged from 63.33 to 68.66%. Results suggest that the entomopathogenic B. bassiana strains are effective against C. capitata puparia but they may be detrimental against its endoparasitoid P. concolor, particularly when applied in the earlier stages of the parasitization process. © 2015, Universita degli Studi di Bologna, Department of Agroenvironmental Sciences and Technologies.
