Ryania Speciosa: an insecticide for organic orchards? Organic Eprints
Kelderer, Markus; Sgarbossa, Manuela; Schönweger, Gudrun; Elias, Ellen; Roland, Zelger; Santer, Johann; Stuppner, Hermann.
Ryania speciosa is a grove belonging to the family Flacourtiacea, located in tropical climates in Central- and South- America. The Indigenous population used the plant, which contains toxic alkaloids, against cockroaches. In the forties the ground wood was used as insecticide against different pests. In the first version of annex 2b from the EC regulation 2092/91, Ryania was still listed, but it was subsequently cancelled due to its lack of registration as a pesticide in any European country. In organic farming, only a few insecticides are allowed, but in orchards there is a permanent need to control larvae such as coddling moth, etc. The Italian Ministry of Agriculture initiated a survey to investigate the possibility of developing an 'organic'...

Versuche zur Regulierung der Wühlmäuse im biologischen Obstbau Organic Eprints
Kelderer, Markus; Lösch, Robert; Lardschneider, Ewald; Casera, Claudio.
In the organic apple orchards in South Tyrol different voles (Fam. Arvicolidae) are the cause of big damages on the trees. At present there isn't any product listed t the annex 2b of the EC- decree 2092/91 for organic agriculture, which could control the voles efficiently. Therefore it is quite difficult to control the voles in organic orchards. It is necessary to convince European and national authorities, associations and organs of control to allow the use of suitable products. Our trials showed that Silmurin, an extract of the red sea-onion (Uriginea marsitima) controls quite efficiently the field mouse (Microtus arvalis), but hasn't any effect against the earth vole (Arvicola terrestris). Against these voles we obtained good results with...

Mode of action of lime sulphur against apple-scab (Venturia inaequalis) Organic Eprints
Zemmer, Franziska; Marschall, Klaus; Kelderer, Markus; Zelger, Roland.
Since lime sulphur was accepted in the annex 2b of the European Regulation 2091/92, more and more fruit growers use it to control apple scab in organic orchards. Field trials were carried out at the Research Centre Laimburg to evaluate stop and curative treatments with the aim to reduce the number of treatments and improving their efficacy. In this diploma thesis microscopic observations were performed for a better understanding of the mode of action of lime sulphur on apple-scab. The results showed that lime sulphur can stop the scab infection until the formation of the appressorium. If the infection proceeds to the formation of the primary stroma, the efficacy of the treatments with lime sulphur was insufficient.

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...

Erste Ergebnisse mit dem Einsatz von K-hydrogencarbonat in Südtirol Organic Eprints
Kelderer, Markus; Casera, Claudio; Lardschneider, Ewald.
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. There is a palpable possibility that it would change in future, what will open the possibility to apply for the introduction of potassium bicarbonate in annex 2B of the...

Tree shading: an efficient method to control alternate bearing? Organic Eprints
Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
Conventional and integrated fruit growers, but not organic producers, have the possibility to use thinning agents (e.g. benzyl adenine), which allow crop regulation at a relatively late stage (10-16 mm fruit size). A few surveys have shown that by reducing net photosynthesis after blossom, June fruit drop increases. This could be an interesting new approach for organic apple orchards. Since 2003, different trials have been carried out at the Laimburg Research Station on the variety Golden Delicious rootstock M9 to devise a method for practical use by fruit growers. Unfortunately, there are still several constraints to the practical application of the shading method, not least because it does not sufficiently reduce alternate fruit bearing in the...

Perennial flower strips for pest control in organic apple orchards - A pan-European study Organic Eprints
Cahenzli, Fabian; Sigsgaard, Lene; Daniel, Claudia; Herz, Annette; Jamar, Laurent; Kelderer, Markus; Kramer Jacobsen, Stine; Kruczyńska, Dorota; Matray, Silvia; Porcel, Mario; Sekrecka, Małgorzata; Świergielg, Weronika; Tasin, Marco; Telfser, Josef; Pfiffner, Lukas.
In many crops, the intensive use of pesticides causes major problems both for the environment and for natural ecosystem services. Apple is Europe's most frequently produced orchard fruit, requiring high pesticide input to combat the most important apple insect pests, Dysaphis plantaginea (Passerini) and Cydia pomonella (L.). Here we sought to control these pests by promoting natural enemies using sown perennial flower strips. We trialled these in the alleyways of organic apple orchards in seven European countries. Visual assessments over two years revealed a higher number of natural enemies on plant parts, and specifically in D. plantaginea colonies on trees, in flower strip plots than on trees in control plots with standard orchard vegetation. Trees in...

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...

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. Growing flowers in order to gain more natural enemies, and hence less pests is a technique called Functional Agro-Biodiversity (FAB). Ongoing research in this CORE Organic Plus project aims to collect existing knowledge and generate new knowledge in order to use FAB successfully in orchards.

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...

Results from two years of sanitation measures to reduce apple scab in organic orchards Organic Eprints
Kelderer, Markus; Lardschneider, Ewald; Marschall, Klaus.
Scab is still a big challenge for those apple orchards which are managed organically. Inoculum survives during winter in leaf litter, and sporulates in spring when vegetation starts. Different surveys in other regions showed that it is possible to reduce the presence of scab in apple orchards by removing the leave litter from the orchards. Different trials were carried out to understand if sanitation measures would also be of practical interest in organic orchards in South Tyrol. The results varied. In some trials, scab was reduced on the leaves up to 60%, in others no differences were observed. It is therefore not clear if the results justify the expense of cost and time for such measures.

Results of 5 years of thinning trials with lime sulphur in South Tyrol Organic Eprints
Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
Thinning trials with lime sulphur were carried out for 5 years on different sites in South Tyrol. The sprays were applied during blossom to various varieties. During these trials different amounts of active ingredients, water volumes and numbers of treatments were used. Beside the thinning effect the influence on yield (kg/tree) and Fruit quality (average size of the Fruits, fruit-russetting, fruit-deformations) and the return bloom of the treated trees were evaluated. In several cases the use of lime sulphur gave satisfactory results (thinning effect >20%). The results showed a correlation with the amount of active ingredient, water volume, and number of treatments. In most of cases it was possible to increase the average Fruit size. The influence on...

Thinning effect of lime sulphur applied during blossom with the overhead irrigation system in comparison to the sprayer Organic Eprints
Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
A large number of organic fruit-growers in South Tyrol regulate scab with scab-stop treatments using the overhead irrigation system. They use mainly lime sulphur, because it is particularly suitable for scab stop treatments. Treatments during blossom can also thin the flowers. The aim of the field-trials was to understand if lime sulphur applied with the overhead irrigation system gives the same thinning effect like the normal application with the sprayer. The results from the 2 years of trials show that there is no significant difference between the two application systems. Other factors like the influence of the different climatic parameters in each year play a more important role.
