Slagtekyllinger reducerede antallet af æblebladhvepse I økologisk dyrkede "Discovery" æbler
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne; Olsen, A.; Korsgaard, Maren; Pedersen, Birgitte.
Samproduktion af fjerkræ og frugt er et emne, som er blevet diskuteret og prøvet i økologisk frugtdyrkning i Danmark. Fjerkræets skraben efter føde kan muligvis formindske populationen af skadedyr, som tilbringer en del af deres livscyklus i jorden.  I økologisk forskning er meget få forsøg med kombineret vegetabilsk og animalsk produktion udført. Behovet for alternative metoder til at regulerer skadedyrspopulationerne meget efterspurgte, fordi økologisk æbleproduktion i Danmark har meget få økologiske sprøjtemidler til rådighed.   Æblehvepsen (Hoplocampa testudinea) giver store udbyttetab i æbler. Æblehvepsene lægger æg under blomstring og larverne ødelægger de små frugter, der falder til jorden før modenhed. Laven overvintre og forpupper sig i jorden....

Spreading of virulence regarding spatial distribution resistant cultivars inferred from population modeling coupled with genetics
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne; Sapoukhina, Natalia; Gladieux, Pierre; Le Cam, Bruno.
One of the control strategies of fungal crop diseases is planting highly resistant varieties. However selection pressure on the pathogen, imposed by major resistance genes, leads to the development of new virulent races. In most cases breakdown of resistance has been reported for crop-pathogen systems with a genetically uniform crop distributed over large areas [2].  Des choix stratégiques en matière de construction et de déploiement de génotypes résistants combinant des gènes de résistance se pose aujourd’hui de manière aigüe afin de tendre vers une agriculture à résistance durable. To reach this objective, we start a study that combined population modeling with genetics to (1) identify keys traits of life of the pathogen involved in resistance breakdown...

Økologisk æbledyrkning
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne.
Økologiske æbler sælges oftest til frisk konsum, hvilket betyder, at de skal leve op til høje kvalitetskrav. Frugterne skal opfylde størrelseskrav og være hele og sunde. Den værste skadevolder er æbleskurv. Skurv forårsager brune til sorte pletter på frugten og kan angribe så kraftigt, at æblerne bliver uegnede til spisning. Denne svampesygdom er årsag til meget stor nedgang i udbytte og kvalitet i økologisk produktion.    Kobber er et effektivt middel mod svampesygdomme og bruges til økologisk æbleproduktion i de fleste europæiske lande. Det er dog ikke godkendt i Danmark, og der er udsigt til et totalt forbud i EU. For at forbedre kvaliteten og udbyttet i en økologiske æbleproduktion må man derfor finde den bedste kombination af kvælstofforbrug,...

Contributions of EU-project REPCO to apple scab control
Provedor de dados: 21
Autores: Köhl, Jürgen; Heijne, Bart; Hockenhull, John; Lindhard Pedersen, Hanne; Trapmann, Marc; Eiben, Ute; Tamm, Lucius.
The objective of REPCO is to contribute to the replacement of copper fungicides in organic agriculture by new measures for control of downy mildew (Plasmopara viticola) in grapevine and scab (Venturia inaequalis) in apple. Both major European organic crops strongly depend on copper fungicides. Permitted amounts will be reduced stepwise during the following years (Council Regulation (EEC) 2092/91, Annex II) to avoid environmental risks. In European countries where copper fungicides are already out of use, production of organic apples suffers severe economical problems because of insufficient scab control.   Potentiators of resistance, organically based fungicides and biocontrol agents are screened and evaluated in apple. Effects of crop management practices...

Sensory evaluation of juice from different organic blackcurrant cultivars
Provedor de dados: 21
Autores: Kidmose, Ulla; Christensen, Lars P.; Lindhard Pedersen, Hanne; Thybo, Anette K.
To ensure a high, stable production of blackcurrant juice in Denmark, it is necessary with high-yielding blackcurrant cultivars, which are resistant against pest and diseases, and that have a high sensory quality and high health value. In this experiment, blackcurrant juice processed from berries of 12 organic cultivars was screened. A trained sensory panel using descriptive sensory profiling evaluated the sensory quality of the juice samples. In addition, the aroma profile and the content of vitamin C were determined in the juice samples. The results showed that the following sensory attributes: blackcurrant aroma, blackcurrant flavour, fruity flavour, pungent flavour, sweetness and sourness varied significantly in the 12 juice samples. In addition the...

Lav gødskning øgede udbyttet ved intensiv æbledyrkning
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne.
Udbytte, frugtkvalitet og angreb af sygdomme i økologisk æbleproduktion bestemmes af et samspil mellem faktorer som tilgængelighed af vand og gødning, grundstammen, plantetætheden og bekæmpelse af sygdomme og skadedyr.    Tidligere forsøg har vist, at den bedste frugtkvalitet og det laveste angreb af sygdomme i semi-tætplantede usprøjtede økologiske æbler (planteafstand på ca. 1,6 m) blev opnået ved relativ lav kvælstof tilgængelighed fra jordens egen mineralisering (se DARCOFenews). Men der ikke afklaret om det samme tilfældet i intensive tætplantede systemer (planteafstande på 0,6-1,2 m).

Soil treatments and rootstocks for organic apple production
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne; Pedersen, Birgitte.
The apple variety 'Retina' is recommended for organic production in Denmark. Yet, there is no knowledge regarding the optimal rootstock for this variety. Better knowledge is also needed on production techniques, such as weed control, where different machinery for mechanical weeding is available.     Therefore, we tested the combined effect of different rootstocks and weeding techniques including soil covering with straw. As organic growers discus the necessity of weed cleaning at all, the natural vegetation was used as control treatment in the trials.

How to optimize fruit and berry cultivar selection for organic farmers ? A comparison of European approaches.
Provedor de dados: 21

Most of the currently grown commercial fruit cultivars remain unsuitable to low-input or sustainable organic farming systems. The major reason is that  they have been developed and selected under high input cultivation, and without sufficient attention to susceptibility to pests and diseases. Some of these cultivars are nevertheless marketed as resistant because they carry genetic markers for major resistance genes but these are unfortunately prone to break-down (most of apple resistant cultivars relay only on the Vf). As a result, new fruit cultivars tend to reveal unexpected and often undesirable traits when grown in commercial organic orchards, and thus fail to bring about the much needed expansion in organic production and market availability. However,...

Sustainable production systems for organic apple production
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne.
Organic apples are often sold for fresh consumption and therefore have to obtain high quality requirements. The fruits must obtain the right size and be undamaged without important infections of pest and diseases. Apple scab causes brown or black spots on the fruits and severe infections can result in fruits not suitable for consumption. This disease causes big reduction in yield and quality in  organic production. Copper is an effective fungicide to control diseases and is used in organic apple production in some European countries. Copper has not been permitted in Denmark the last 10 years and the European Union wants to reject it from the list of pesticides permitted in organic production. To improve the quality and yield in organic apple production, it...

Broilers reduce the apple sawfly population in organic apple growing
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne; Olsen, A.; Korsgaard, Maren; Pedersen, Birgitte.
In organic production in Denmark, no pesticides are allowed. The need for alternative pest control is therefore large. Apple sawfly (Hoplocampa testudinea) cause big crop losses in apples. Sawflies infest fruitlets and cause these to drop prematurely after which the pests pupate in the topsoil.    Combined production of hens and fruit trees is a subject often discussed in organic fruit production in Denmark. The feeding poultry may reduce the population of pests, which stay in the soil as a part of their life circle. Yet, very little research has been carried out on this type of production system.

Lower nitrogen supply gave better fruit quality in organic apples
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne; Bertelsen, Marianne.
In a questionnaire send out in the mid 90’ties, organic growers estimated a yield reduction of at least 86 per cent compared to conventional production. The estimation was based on production of the most common conventional grown varieties. The main reason for this low productivity is lack of control methods against diseases and pests, especially apple scab (Venturia inaequalis) (Lindhard et al., 1998). In Denmark, most organic pesticides are not registered. For instance, copper has not been on the market for 7 years.

However selection pressure on the pathogen, imposed by major resistance genes, leads to the development of new virulent races. In most cases breakdown of resistance has been reported for crop-pathogen systems with a genetically uniform crop distributed over large areas[2]. To derive strategies leading to durable resistance we focus on studying the role of recombination of pathogen genotypes and their spread in the process of succes-sive breakdowns of resistant hosts carrying different major resistance genes and their pyramids.
