    On-farm and on-station evaluations of three orchard management approaches against apple scab and apple powdery mildew
    Holb, I.J. ; Abonyi, F. ; Buurma, J. ; Heijne, B. - \ 2017

    Apple scab - Fungal disease management - Integrated disease management - Malus x domestica - Pesticide risk reduction - Powdery mildew
    In a three-year study (from 2012 to 2014), the efficacy of three apple management approaches (conventional, standard and advanced Integrated Pest Management - CON, IPM1 and IPM2, respectively) was aimed to investigate against apple scab and apple powdery mildew in on-station (small research scale) and on-farm (real large farm scale using existing farm equipment) experiments in order to promote practical adoption of environmentally sustainable management methods. CON used generally applied conventional pest management practices (disease/pest forecasting coupled with conventional pesticide use). IPM1 used a generally applied integrated pest management practices in most European countries (disease/pest forecasting, yellow/green-list fungicide use coupled with pruning against both diseases, yellow/green-list insecticide use coupled with mating disruption against insects). IPM2 used an advanced integration of known non-chemical practices, accepting most principles of organic farming guidelines (disease/pest forecasting, delayed fungicide applications with green-list fungicide use, pruning against both diseases coupled with orchard sanitation, biological control and mating disruption against insects). Scab and powdery mildew incidences were not significantly different between IPM1 and CON while disease incidences were significantly higher in IPM2 compared to either CON or IPM1 (P = 0.05). Overall yield was not significantly different among the three management approaches. However, the amounts of first class fruit were the highest in CON and IPM1 which were significantly higher (P = 0.05) than that of in IPM2. The amount of second class fruit was the highest in IPM2, indicating a lower fruit quality in IPM2 than in CON or IPM1. In addition, overall disease incidences and fruit quality were generally lower in the on-farm than in the on-station conditions. Our research suggested that elements of IPM1 can be easily adopted by apple growers. Despite the advanced integration of non-chemical control practices in IPM2, its future adoption will depend on the control efficacy and the economic sustainability of non-chemical control practices.

    Apple - Cost-benefit analyses - Dexipm - Ex-ante assessment - Ex-post assessment - Integrated pest management - Pear - Premise - Synops

    Research on innovative Integrated Pest Management (IPM) tools is done onstation and on-farm in the PURE project. The idea is that IPM tools are tested under well-defined conditions in experimental orchards. Subsequently, they are tested in commercial orchards as part of a total IPM system where drawbacks and bottlenecks become clear. In subsequent on-station experiments the drawbacks or bottlenecks are solved and adjusted IPM tools are again tested in commercial orchards. We call this the "design - assessment - adjustment cycle". It is meant, together with co-innovation techniques, to promote uptake of innovative IPM tools by commercial farmers. For apple, new innovations are the use of exclusion netting against codling moth (Cydia pomonella), and the use of an antagonist against conidia of Venturia inaequalis. For pear, the overwintering inoculum of brown spot of pear (Stemphylium vesicarium) is reduced by antagonists and natural fertilisers, and the control of pear sucker (Cacopsylla pyricola) is promoted by natural enemies. For both apple and pear an innovative canopy adapted sprayer is used to reduce emissions and to further reduce pesticide use. Efficacy of these innovative IPM tools and IPM systems is assessed by the newly developed software for environmental effects: SYNOPS, for economic effects: PREMISE, and for overall sustainability, including economic, social and environmental aspects: DEXiPM-pomefruit. Results show that the overall sustainability of the conventional system is already high. Nevertheless, innovative IPM tools provided an improvement of environmental quality with an efficient control of diseases or pests. The cost for running the innovative IPM systems was often higher than the conventional system.

    Extensive literature search on cropping practices of host plants of some harmful organisms listed in Annex II A II of Directive 2000/29/EC

    The European Commission is currently seeking advice from EFSA (Mandate M-2012-0272) to assess for Arabis mosaic virus, Raspberry ringspot virus, Strawberry latent ringspot virus, Tomato black ring virus, Strawberry mild yellow edge virus, Strawberry crinkle virus, Daktulosphaira vitifoliae, Eutetranychus orientalis, Parasaissetia nigra, Clavibacter michiganensis spp. michiganensis, Xanthomonas campestris pv. vesicatoria, Didymella ligulicola and Phytophthora fragariae the risk to plant health for the EU territory and to evaluate the effectiveness of risk reduction options in reducing the level of risk. In addition, the Panel is requested to provide an opinion on the effectiveness of the present EU requirements against these organisms laid down in Council Directive 2000/29/EC. As a consequence EFSA needs insight in the cropping practices of Citrus spp., Fragaria x ananassa, Ribes spp., Rubus spp., Vaccinium spp., Humulus lupulus, Vitis vinifera, Prunus armeniaca, P. avium, P. cerasus, P. domestica and P. persica, which are host plants for these pests. An extensive and systematic literature search was done in which scientific and grey/technical literature was retrieved from the 28 EU Member States, Iceland and Norway. All references were stored in EndNote libraries, separately for scientific literature and grey/technical literature. For each reference information is provided on the source/search strategy, the crop, the country, the topic (cropping practice, propagation, protection or irrigation (only for Citrus)) and protected cultivation vs. field production. Yields of references depended on the crop and on the country. Over 27,000 references were provided to EFSA. This allows EFSA to quickly find information on crop production, both indoors and outdoors, of all crops that were studied in this extensive literature search. The data can be used by EFSA for the present mandate, but are also an excellent basis for other current and future mandates.
    Hypothetical pear production system innovation through promotion of soil biodiversity
    Maas, M.P. van der; Heijne, B. - \ 2014
    In: Proceedings of the 1st IS on Organic Matter Management and Compost Use in Horticulture. - Leuven, België : ISHS - ISBN 9789462610040 - p. 215 - 221.
    We developed a hypothetical view on a pear production system innovation through promotion of soil biodiversity. Two types of measures form the central idea of the innovation. The first type of measure is to replace part of the current 100% mineral fertilisation by compost plus targeted use of specialised soil and leaf fertilisers. The second type of measure is to replace pesticides harmful for soil life by alternative measures or non-harmful pesticides. We anticipate that these measures would have three main effects. The first effect is improved soil life, the second is reduced environmental impacts, and the last is increased economic profit for the fruit grower.

    The design of fruit production systems considering the latest innovations is a real challenge. Before being tested in an experimental station or in real farm conditions, the global sustainability of these newly designed orchards needs to be evaluated. Based on the DEXiPM® model, the DEXiPM-pomefruit tool has been designed to make an ex ante assessment of the sustainability of innovative orchard systems. This model is based on a decision tree breaking the decisional problems of sustainability assessment into simpler units, referring to the economic, social and environmental dimensions of sustainability. Based on two case studies, we present here the steps and thought process of our group to improve fruit production systems towards innovative and integrated production systems. DEXiPM-pomefruit tool has been tested on apple and pear production systems in the frame of a working group of European researchers. It proved to be sufficiently reliable to select the most promising innovations in a given context. DEXiPM-pomefruit was also used as a dashboard to determine strengths and weaknesses of the tested production systems and therefore to identify improvements.
