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...

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...

Was bringen die derzeit 'verfügbaren' Bioherbizide? Organic Eprints
Kelderer, Markus; Casera, Claudio; Lardschneider, Ewald.
Mainly in Anglo-Saxon countries (USA, New Zealand etc.) the market for organic agriculture inputs offers different natural substances for the use as bio-herbicides. The most important ingredients of these products are acetic acid, citric acid and clove-extracts (eugenol) in the case of post-emergence herbicides and corn-gluten in pre-emergence products. In a first screening test we compared the efficacy of these ingredients with some other natural substances. The most interesting ones were later compared in a field trial where the efficacy and the required dosages to clean a strip of about 40 cm under the trees were assessed in an ap-ple orchard. A few products showed interesting results (vinegar, pine oil), but the required dosage to keep the strip under...

Phytotoxicity of different sulphur products applied with the sprayer or with the overheat irrigation system on Braeburn apples Organic Eprints
Kelderer, Markus; Casera, Claudio; Lardschneider, Ewald.
The apple variety Braeburn is very popular among the organic apple growers in South Tyrol. Braeburn brings high and regular yields and good prices at the north European fruit and vegetable market. Braeburn is quite susceptible to scab and mildew. To regulate this latter disease the organic orchardists use mainly sulphur products. Braeburn however is sensitive to sulphur treatments. Mainly during summer at high temperatures the leaves of Braeburn treated with sulphur develop a yellowish colour and necrotic spots. A field-trial was carried out for 2 years to investigate which sulphur formulations and application techniques give less phytotoxic problems to leaves and fruits of the apple variety Braeburn. The results show only small differences between...

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...

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...

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.

Winter treatments against the woolly apple aphid (Eriosoma lanigerum): products and timing of applications Organic Eprints
Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
In organic apple growing the woolly apple aphid (Eriosoma lanigerum) is still an unsolved problem. Various approaches to use beneficial insects were not really effective. Only winter treatments with mineral oils showed partial and fluctuating success. In 2006 and 2007 field trials were carried out to evaluate the efficacy of winter treatments to control woolly apple aphids. The efficacy of several products (different mineral oils, lime sulphur, and lime sulphur + mineral oil) was tested in comparison to an untreated control, and possible side effects on the population of predatory mites were investigated. The study furthermore aimed at establishing the best timing of the application against the target pest.

Vinasse: an alternative to lime sulphur for flower thinning? Organic Eprints
Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
Thinning trials with vinasse in comparison to lime sulphur were carried out for 4 years at different sites in South Tyrol. Beside the thinning effect, the influence on fruit quality, phytotoxic damage on the leaves and the return bloom of treated trees were evaluated. Depending on the dosage the vinasse treatments showed a good thinning effect, but russetting and leave damages were significantly higher in comparison to lime sulphur. Return bloom of vinasse treated trees was lower than of those treated with lime sulphur. In conclusion, vinasse treatments can not substitute lime sulphur for flower thinning in organic apple orchards.
