| Die Wirkung praxisüblicher Leuchtstoffröhren mit unterschiedlichem Wellenlängenspektrum in zwei Beleuchtungsstärken auf das Keimlängenwachstum und den Ertrag der Kartoffelsorten 'Belana' und 'Nicola' wurde 2008 und 2009 auf dem ökologisch bewirtschafteten Versuchsbetrieb Wiesengut in Hennef geprüft. Das Längenwachstum der Keime wurde bei beiden Sorten durch Pflanzenlicht und Warmtonlampen stärker gehemmt als durch Kalttonlampen mit einem geringen Anteil an rotem Licht (Wellenlänge ~700 nm). Bei höherer Beleuchtungsstärke waren die Keime bei beiden Sorten zum Zeitpunkt der Pflanzung kürzer als bei niedriger Beleuchtungsstärke. Die keimfreudige Sorte 'Nicola' reagierte auf veränderte Beleuchtung deutlich stärker als Belana. Der Knollenertrag wurde durch die... |

| From 2013 2015, the release and establishment of predatory mites for the control of two-spotted spider mites, Tetranychus urticae, was conducted in five hop gardens of The species compared were the autochthonous mites Typhlodromus pyri, Amblyseius andersoni and a mix of the two allochthonous species Neoseiulus californicus and phytoseiulus persimilis. Main objective was the establishment of a permanent population of T. pyri in a hop garden by providing the predators with structures for their hibernation by undersown crops. We chose seeding of tall fescue Festuca arundinacea, a grassland seed mixture and strawberries as an intercrop in the wheel lanes. During the three project years, 15 trials were conducted of which however only two yielded meaningful... |

| Bitkilerin çoğu çiçek tozlarının yayılmasında, böceklere bağımlıdır. Bal arıları, Bombus arıları ve yaban arıları farklı bitki türlerinin çiçekleri arasında bakteri ve fungal sporların taşınmasında da rol oynamaktadır. Fungus, bakteri ve virus gibi mikrobiyal biyolojik mücadele etmenleri bitki hastalıkları ve bitki zararlısı böceklerin mücadelesinde kullanılabilmektedir. Mikrobiyal biyolojik mücadele etmenlerinin (fungus, bakteri ve virus) kovandan çiçeklere taşınmasında, bal arılarının taşıma yeteneğinin kullanılması entomovektör teknolojisi olarak bilinmektedir. Bu teknoloji ile bitki zararlısı böcekler ve bitki patojenlerine karşı çevreye zararsız mücadele yapılmakta ve bitkilerde tozlaşmanın da artırılmasıyla verim ve ürün kalitesinde artış olmaktadır.... |

| Two myco-insecticides, Naturalis-L (Beauveria bassiana) and PreFeRal®WG (Paecilomyces fumosoroseus), were applied against adult R. cerasi Loew (Diptera: Tephritidae) in two orchards in north-western Switzerland in summer 2006. Both products were applied at a concentration of 5.75x104 CFU/ml. With four applications at seven day intervals the whole flight period of R. cerasi was fully covered. During this period the relative humidity averaged 66.3% (5th June – 6th July), the temperature averaged 20.5°C. Under these conditions only Naturalis-L significantly reduced the number of damaged fruit (efficacy: 69-74%), whereas damaged fruits were not significantly reduced with PreFeRal (efficacy: 27%). For B. bassiana living fungal propagules were still detectable... |

| Kartul on üheks armastatumaiks kultuuriks nii meil kui maailmas. Teda on läbi aegade peetud teiseks "leivaks" ning tänapäeval ei kujutaks meist keegi ette oma toidulauda, kust puuduks kartul (Eremeev jt., 2012). Hea eelkultuurina teraviljadele sobib ta hästi ka päikesepinnalistesse külvikordadesse. Kartulit saab edukalt kasvatada maheviljeluslikus suletud tsükliga tootmisüksustes, kus on võimalik kasutada loomapidamisest tekkivad sõnnikut (Järvan ja Edesi, 2012). Maheviljeluslikus külvikorras on oluline osa vahekultuuride kasvatamisel. Põhikultuuride kasvatamise vahepealsel ajal vahekultuurid kaitsevad ja rikastavad mulda toitainetega ning suruvad alla umbrohtumust. Vahekultuure ei kasvatata müügikasu eesmärgil, vaid sissekündmisel muutub see... |

| Organic farmers face the same potentially severe pest problems as their colleagues in integrated pest management (IPM) and conventional farming systems. However, approaches to manage the pest insects are different because the aim of organic farming is a holistic system perspective rather than simple reductionist control approaches. Organic cropping systems are designed to prevent damaging levels of pests, thus minimizing the need for direct and curative pest control (Peacock and Norton, 1990). Within the following chapter, we will briefly explain the standards for organic farming, which also set the framework for pest control. We present a conceptual model for pest control in organic farming and describe the influence of functional agro-biodiversity and... |

| Es muss nicht immer die teure Chemiekeule im Kampf gegen Schimmel sein. Wissenschaftler aus Finnland bringen Bienen dazu, auf Erdbeeren einen Pilz aufzutragen, der gegen den Befall schützt - ganz natürlicher Pflanzenschutz. In Deutschland will man die Idee noch optimieren. |

| Pest and diseases can have a significant effect on the establishment, yield and longevity of grass and forage crops. This tool is an atlas for the identification of the main pests regarding grass and forage crops. It has been written for Wales climates and it is not specific for organic farming. Nonetheless, the information contained, can be used by farmers, conventional or organic, skilled or newcomers, all over Europe. Besides pest descriptions, with pictures that facilitate the task of identification, it provides useful hints on preventive, non-chemical, practices to reduce pest incidence. |

| Abstract Plant virus epidemiology provides powerful tools to investigate key factors that contribute to virus epidemics in agricultural crops. When successful, epidemiological approaches help to guide decisions regarding plant protection strategies. A recent example is epidemiological research on Potato virus Y (PVY) in Finnish seed potato production; this study led to the dentification of the main PVY vector species and helped to determine the timing of virus transmission. However, pathosystems rarely allow research to produce such clear-cut results. In fact, the notorious complexity of plant virus pathosystems, with multiple interactions between virus, vector, plant and environment, makes them often impenetrable even for advanced epidemiological models.... |
