| Le mildiou de la laitue (Bremia lactucae) est la maladie la plus redoutée sur cette espèce, notamment en culture biologique d’hiver sous abris. En Provence, les dégâts sont très importants, parfois dès la pépinière, et entraînent de fortes pertes financières. Cette situation est due à deux facteurs principaux : d’une part au contournement récurrent des résistances génétiques par de nouvelles souches de Bremia (26 races déterminées à ce jour), et d’autre part à la faiblesse des méthodes de lutte biologique possibles contre ce champignon (notamment la faible efficacité des traitements à base de cuivre). Cet essai consiste en un test de produits alternatifs de différentes natures (extraits de plantes, produits minéraux...). |

| 1. Feldversuche Die Winterweizensorten Arina und Capo wurden im Versuchsjahr 2002/2003 auf insgesamt 12 Standorten im Ökologischen Anbau als Reinbestände und als Sortenmischung angebaut. Das Versuchsjahr war extrem trocken, weshalb kein relevanter Krankheitsbefall zu verzeichnen war. Die Erträge variierten je nach Standort von 26 bis 53 dt/ha wobei Capo deutlich ertragsstärker war als Arina. Die Mischung brachte im Schnitt 3% mehr Ertrag als erwartet und war im Ertrag deutlich stabiler. Dies war auf die stärkere Konkurrenzkraft der Sorte Capo an fast allen Standorten zurückzuführen. Arina übertraf Capo signifikant im Rohprotein (RP) (12.9 versus 12.2%) und Feuchtklebergehalt (FK) (29.8 versus 25.3%), was auch im Backvolumen reflektiert wurde. Während bei... |

| Venturia inaequalis causes apple scab. The control of the disease in organic apple production depends on the use of copper which will be restricted in future for environmental reasons. In the search for environmental friendly microbial biocontrol agents and stimulation of antagonistic populations in situ the molecular technique of DGGE fingerprinting can is applied. This fingerprinting technique allows to bypass culturing techniques and even can identify not yet culturable organisms. Comparison of microbial fingerprints and pathogen development in the leaf samples during winter and spring has been performed to identify populations with antagonistic potential. Such potential antagonistic organisms can be further identified by their specific DNA... |

| Für Landwirte und Gärtner, die unter Bedingungen des Ökologischen Landbaus wirtschaften, gehört der Pflanzenschutz zum qualitäts- und ertragsbestimmenden Wirtschaftsfaktor. Aus diesem Grund wurde 2003/2004 vom Julius Kühn-Institut der Bereich Pflanzenschutz im Internetportal www.oekolandbau.de erarbeitet. In diesem Bereich wurden Themenblöcke entwickelt, in den die bedeutendsten Schaderreger und Nutzorganismen beschrieben wurden. Neben Angaben zum Schadbild und zur Biologie wurden vorbeugende und direkte Maßnahmen zur Regulierung erörtert sowie entsprechende Weblinks zu weiterführenden Themen angeboten. In den letzten Jahren sind auf dem Gebiet der Forschung zum Pflanzenschutz im Ökologischen Landbau einige Projekte bearbeitet und neue Erkenntnisse auf... |

| Das Projekt EU-ORWINE befasst sich mit der Entwicklung umwelt- und verbraucherfreundlicher Herstellungsverfahren und rechtlicher Grundlagen. Der biologische Weinbau ist ein bedeutender Zweig der biologischen Landwirtschaft. Dennoch fehlen bislang in der EU Verordnung 2092/91, welche die rechtliche Grundlage des biologischen Landbaus darstellt, Richtlinien für die biologische Weinherstellung und für eine entsprechende Kennzeichnung von biologisch erzeugtem Wein. Dies führte dazu, dass eine beträchtliche Menge biologisch erzeugten Weines konventionell vermarktet werden muss. Darüber hinaus sind die in mehreren EU-Ländern von biologischen Anbauverbänden entwickelten privaten Standards zur Weinherstellung heterogen hinsichtlich erlaubter Zusatz- und... |

| Different strawberry varieties, available from organic propagation at that time were, planted in August 2004 and proofed about their suitability for organic cultivation, each variety was tested with and without biodegradable mulch film. Within the early ripening strawberry varieties ‘Clery’ had a middle yield and was susceptible for infections with leaf spot, losses of plants by Verticillium were seldom. This variety should be planted early to reach enough vigor in autumn. ‘Clery’ has an interesting potential in the phase of higher prices at the beginning strawberry season. ‘Darselect’ ripened shortly before ‘Elsanta’, the yield was lower, but the fruit-size bigger, so the picking could be done more quickly. ‘Elsanta’ showed in this trial under... |

| Økologisk frugtavl dyrkes i hele verden, og der forskes en del i metoder til forbedring af resultatet. Problemerne varierer lidt, men både sortsvalg, ukrudtsbekæmpelse og plantesystemer er fælles udfordringer. Konferencen ”Organic Fruit 2012” blev afholdt i staten Washington i USA i juni, og der blev fremlagt mange spændende forsøgsresultater. Takket være støtte fra Fonden for Økologisk Landbrug deltog jeg i konferencen og vil her bringe de bedste tip videre. |

| The effects of a fogging system on the control of the two-spotted spider mite (Tetranychus urticae) were studied in greenhouse cultivation of eggplant, cucumber and strawberry during the period 1999-2006. At the beginning the pest and the phytoseiid predator Phytoseiulus persimilis were released on the crops and then observations were made on the development of the populations of both mites. Fogging system effects were found in terms of lowering the T. urticae population and hindering the growth of powdery mildew fungus. Furthermore there was a yield increase in the cases of strawberry and cucumber in 2001 but no negative impact on pest management was ever detected, particularly on the biological control of the melon aphid (Aphis gossypii) achieved using... |

| Fifty spring barley varieties grown under organic as well as conventional growing conditions in experimental fields in four combinations of year and site were studied. The yield varied much within and between environments (years and sites) and systems. Further, the variation between varieties was substantially and it differed between different environments and systems. Associations between observed grain yield of these varieties and disease and growth characteristics assessed in the official conventional variety testing were compared between the organic and the conventional system. Using factorial regression analysis, the best model for predicting the observed grain yield each year from these characteristics the previous year was found. In this model, the... |

| Dette projekt har fokuseret på direkte bekæmpelse af tre skadegørere i økologisk ribs og solbær, nemlig den lille frostmåler Operophtera brumata, L. (Lepidoptera: Geometridae), viklere, primært hækvikler Archips rosana (L.) (Lepidoptera; Tortricidae) og ribsbredvingemøl Lampronia capitella (Clerck) (Lepidoptera; Prodoxidae). Behandlinger blev testet i en mark på 0,78 ha opdelt mellem solbærsorterne Ben Hope og Titania og i ribssorten Rovada. Vi anvendte et randomiseret blok design. I 2011 sammenlignede vi behandlinger med insektsæbe, rapsolie og Bacillus thuringiensis i Rovada og Titania. I Ben Hope sammenlignede vi blandinger af disse midler samt blanding med pyrethrum. I 2012 fortsatte undersøgelserne. Dette år indgik neem, sammen med B thuringiensis og... |

| Background and objectives Two pathogens growing on the same leaf compete for the same resources, i.e. space and plant nutrients. This may lead to density dependent disease development. The pathogens may also influence each other directly such that the influence of one on the other is more complex than a simple function of the area of the other pathogen. Different interaction types are, for example, competition, mutualism and exploitation. The importance of such interactions for epidemics of simultaneously occurring pathogens has received little attention. The objective of this study is to investigate the simultaneous epidemic development of Rhynchosporium secalis (causing scald) and Drechslera teres (causing net blotch) on spring barley under field... |

| Broad-leaved dock (Rumex obtusifolius L., Polygonaceae) is an agronomically important perennial weed causing decreases in pasture yields and fodder quality. Non-chemical control measures for dock are often limited to frequent pulling and cutting, additionally it is usually avoided by grazing animals. Here, the regeneration of R. obtusifolius in a Rumex-infested grassland grazed by a sheep breed that explicitly feeds on dock (Ovis aries L. cv. East Prussian Skudden) was compared to cutting. Therefore, regeneration of 90 R. obtusifolius plants of three different size classes was monitored in three plots during three grazing and cutting cycles. Plant height and number of fruit-stands of regrown R. obtusifolius was significantly lower, number of... |

| More and more organic farmers lift potatoes which are damaged by wireworms (Agriotes spec. and Hemicrepidus niger). A nationwide status quo-analysis was carried out by the Chamber of Agriculture of North Rhine-Westphalia in 2002 and 2003. The survey included an intensive literature research, a questionnaire with 26 questions, on-site assessments, and on-farm trials. It was noticed that a long period of grass-clover cultivation in the crop rotation had a negative effect on the quality of potato tubers. Peas and lupines seemed to be the better pre-crops for a good quality of tubers in contrast to field beans and red clover. An autumn fertilization with manure resulted in a low feeding damage on potatoes by wireworms. Many perennial weeds some like... |
