A comparison between organic and integrated apple production: First results after 5 years of observation Organic Eprints
Kreuzwieser, Andreas; Kelderer, Markus.
Organic apple production is of increasing commercial importance throughout Europe, but especially in South Tyrol where about 25% of the whole European organic apple crop is produced. In organic apple production, producers face the challenge of choosing varieties that are both in demand and also resistant to the main pests and diseases. Every now and then, the question arises, if yields, losses and profitability are different in integrated and organic orchards and in how great are the differences between single apple varieties. In 1999 the Laimburg Research Centre started a field trial to observe the effects of different cultivation methods on 18 apple varieties in a randomised block design. In the first four years of production, significant...

Apple scab control with grapefruit seed extract: no alternative to chemical fungicides Organic Eprints
Spitaler, Renate; Marschall, Klaus; Zidorn, Christian; Kelderer, Markus; Zelger, Roland; Stuppner, Hermann.
The growth inhibiting effect of four commercially available grapefruit seed extracts on the causal organism of apple scab Venturia inaequalis was tested. Germination of the conidia of Venturia inaequalis was pronouncedly inhibited by all tested extracts. The commercial products were analyzed by high pressure liquid chromatography and thin layer chromatography. All samples contained at least one preserving agent. These substances were identified as either benzethonium chloride, benzalkonium chloride, methyl parabene or propyl parabene. Freshly prepared extracts from seeds of grapefruits (Citrus paradisi) did not inhibit the germination of Venturia inaequalis. It was therefore concluded that the antifungal effect of grapefruit seed extracts is...

The project CO-FREE (2012-2016) aimed to develop strategies to replace/reduce copper use in organic, integrated and conventional farming. CO-FREE alternative test products (CTPs) were tested and integrated together with decision support systems, disease-tolerant varieties, and innovative breeding goals (ideotypes) into improved management strategies. CO-FREE focused on apple/apple scab (Venturia inaequalis), grape/downy mildew (Plasmopara viticola), and tomato and potato/late blight (Phytophthora infestans). Starting point of the project were ten CTPs with direct or indirect modes of action including Trichoderma atroviride SC1 and protein extract SCNB, Lysobacter spp., yeast-based derivatives, Cladosporium cladosporioides H39, the oligosaccharidic complex...

Degradation behaviour of potassium K-phosphite in apple trees Organic Eprints
Kelderer, Markus; Matteazzi, Aldo; Casera, Claudio.
Although potassium phosphite is not registered for organic fruit production in Europe, it has long been regarded as a potential alternative to sulphur- and copper-containing fungicides. In 2005/2006 a field trial was carried out to verify the presence of residues of phosphoric acid over time in apples after applications of potassium phosphite at different time-points. No residues were present on fruits if treatments were applied before flowering, whereas treatments after flowering, in the summer or in autumn resulted in comparable residue levels irrespective of the period of application. Residues were eveneven found in leaves and fruits of the following years, 2006 and 2007.

Design, implementation and management of perennial flower strips to promote functional agrobiodiversity in organic apple orchards: A pan-European study Organic Eprints
Pfiffner, Lukas; Cahenzli, Fabian; Steinemann, Beatrice; Jamar, Laurent; Chor Bjørn, Mona; Porcel, Mario; Tasin, Marco; Telfser, Josef; Kelderer, Markus; Sigsgaard, Lene.
Orchards, as intensive cropping systems, often have low diversity of plant species, which limits the promotion of natural enemies for pest control. The implementation of agri-environmental schemes, such as flower strips, could enhance biological control. We developed perennial, multifunctional flower strips with native plant species. In the second and third year after sowing, plant diversity and ground cover between flower strips (FS) in the drive alleys and the spontaneous orchard vegetation in control plots (Cont) were compared in 19 experimental blocks of eight organic apple orchards in six European countries. On average 73.7% of the sown plant species were established and plant diversity of FS was on average 43% higher than in Cont. Multivariate...

EcoOrchard – collecting existing knowledge and generating new knowledge on functional biodiversity of organic orchards Organic Eprints
Sigsgaard, Lene; Warlop, Francois; Herz, Annette; Tchamitchian, Marc; Pfiffner, Lukas; Kelderer, Markus; Jamar, Laurent; kruzynska, Dorota; Korsgaard, Maren; tasin, Marco; Ozoliņa-Pole, Laura.
Organic fruit growers often suffer economic losses due to insect damages. The available natural pest control products are not always effective; and most important: many organic fruit growers would prefer not to use any pesticide at all. EcoOrchard, a CORE Organic Plus project (2015-18) aims to collect existing knowledge and generate new knowledge in order to use Functional AgroBiodiversity (FAB) successfully in orchards. This includes experimental trials in seven countries on the potential of inter-row flower strips for control of key pests and natural enemy augmentation, the establishment of the EBIO-Network as a European-wide network of stakeholders for collecting, sharing and improving scientific and practical knowledge and experience in FAB...

Effects of the period of application of K-phosphite on residues on apple fruits Organic Eprints
Kelderer, Markus; Matteazzi, Aldo; Casera, Claudio.
K-phosphite is very efficient against several plant diseases. Nevertheless at the moment there is no official registration in Europe as a plant protection material. In conventional winegrowing K-phosphite is used in different countries to regulate the main disease ‘Plasmopora viticola’ under the disguise of a foliar fertilizer or a plant strengthener. In organic apple production only a few fungicides to regulate scab are available. In addition, copper products are limited by European and national legislations. The discussion about Kphosphite for organic farming points always at the problem of synthetic residues on the edible parts of the vegetables. The aim of this field-trial carried out during the season of 2005 was to assess the residues on...

Efficacy of copper alternatives applied as stop-sprays against Plasmopara viticola in grapevine Organic Eprints
Lukas, Kathrin; Innerebner, Gerd; Kelderer, Markus; Finckh, Maria R.; Hohmann, Pierre.
The six products, Armicarb, Vitisan, lime sulphur, Caso, Calce Fiocco and Ulmasud were tested for their ability to control downy mildew (Plasmopara viticola) on grapevine (Vitis vinifera) in order to find effective alternatives to copper, a heavy metal that is commonly used as a fungicide in organic viticulture. Each product was applied to potted grapevines at i) 40°h (degree hours) and ii) 80°h after inoculation (ai) of the pathogen. These so-called stop-sprays were tested on plants that received two different P. viticola inoculum rates. The formulated potassium bicarbonate product Armicarb and lime sulphur reduced disease incidence and severity similar to or better than the copper hydroxide treatment. Armicarb and lime sulphur reduced disease incidence...

ENDOPHYTIC FUNGAL POPULATIONS ACTING ON SOIL SUPPRESSIVENESS IN FRUIT TREE ORCHARDS Organic Eprints
Manici, L.M.; Kelderer, Markus; Caputo, F.; Nicoletti , F.; Topp , A..
The aim of the present study was i) to identify the soil inhabiting endophytic fungal populations having beneficial impact on crop health; ii) to identify the biological processes responsible of this functional effect. Activity was performed on fungal populations extracted from the microbial population of soil samples coming from three apple growing areas of Europe. Functionalities of Fusarium oxysporum and binucleate Rhizoctonia observed in this study are two small examples of soil biological resources that could be exploited in organic agriculture for developing innovative cropping practices.

In the EC at the moment only cupper and sulphur products are allowed to regulate a multiplicity of diseases in different vegetable crops. On the other hand it is well know that both have also negative side effects on beneficial organisms and the soil. Since many years researches are looking for alternatives to reduce and substitute the use of the mentioned products. Bicarbonates are substances which were pointes out for many years. They are present in nature and were used in the past in organic farming. Until now there was no registration for them in the EC as plant protection materials.

Formulated and unformulated carbonates to control apple scab (Venturia inaequalis) on organic apple Organic Eprints
Kelderer, Markus; Claudio, Casera; Lardschneider, Ewald.
In the EC at the moment only copper- and sulphur-based products are allowed to control a variety of diseases on different crops. However, it is well-known that these products also have negative side effects on beneficial organisms and the soil. For many years researchers have been looking for alternatives to reduce their use and /or replace them. Bicarbonates have been brought forward for many years. They are present in nature and were used in the past in organic farming. Up to now, in the EC, carbonates have not been included in the list of active substances, which may be used as plant protection products. A good chance exists that this will change in the future, which would open the possibility to apply for the inclusion of potassium hydrogen...
