AN ALTERNATIVE APPROACH TO PLANT HEALTH: THE PROCEDURAL CONCEPT APPLIED TO COMMON BEAN SEED SYSTEMS Organic Eprints
Klaedtke, Stephanie; Stassart, Pierre; Chable, Véronique.
Pathogen-free seed is one strategy to protect plants and prevent the introduction and spread of dangerous pests. While this strategy reduces damage to crops and delays the global spread of pathogens, it may also be regarded as an overly reductionist approach to plant health disfavoring the resilience of cropping systems. Rather than defining plant health as an objective entity, a procedural concept consisting of a set of rules for debate in order to incorporate different viewpoints on the continua between naturalist and normativist approaches, negative and positive definitions, reductionism and holism and functionality and resilience has been proposed. In the ongoing research project presented here, the questions suggested are applied to the case of...

Concepts of plant health – reviewing and challenging the foundations of plant protection Organic Eprints
Döring, Thomas; Pautasso, Marco; Finckh, Maria R.; Wolfe, Martin.
Plant health is a frequently used but ill-defined term. However, there is an extensive literature on general health definitions and health criteria in human medicine. Taking up ideas from these philosophical debates, concepts of plant health are reviewed and a framework developed to locate these concepts according to their position in several philosophical controversies. In particular, (i) the role of values in defining plant health in a naturalist versus a normativist approach; (ii) negative and positive definitions of plant health; (iii) reductionist versus holistic perspectives; (iv) the focus on functionality versus resilience, i.e. the ability of the plant to perform under stress with or without human interference; (v) materialist versus vitalist...

Experimentação didático-pedagógica: uma proposta de controle biológico de pragas para agricultores urbanos Organic Eprints
Souza, Brígida; Cássia, Rebeca.
Devido às características particulares que apresenta, a agricultura urbana demanda tecnologias de produção que evitem o uso de agrotóxicos, como o controle biológico de pragas. Objetivou-se construir alternativas para o uso desses produtos na realidade dos agricultores da Horta Comunitária da COHAB, localizada na periferia de Lavras, MG, onde foram constatados danos por pulgões na couve (Brassica oleracea var. acephala). Para tanto, foi desenvolvido um ensaio técnico-pedagógico, o qual foi dividido em dois testes: um no campus da Universidade Federal de Lavras (UFLA), a fim de construir possibilidades para o uso local do controle biológico, em especial do predador Ceraeochrysa cubana; e outro na horta comunitária, que objetivou o reconhecimento da ação de...

HOMOEOPATHY IN AGRICULTURE Organic Eprints
Singhania, Pawan Kumar; Singhania, Archana.
Homoeopathy medicines have been found to be effective in human organisms. Research and application of Homoeopathy drugs in agriculture is slowly finding place. The mode of action of Homoeopathy remedies and simillinum of drug pictures for use in agriculture; basic principles of Homoeopathy and drug administration are discussed. Significant results have been observed using Homoeopathy medicines to fight stress conditions during wet conditions; during hot and dry conditions; in improving germination and growth; to control pest, disease and viral infection, etc. on various crops have been reported.

How to optimize fruit and berry cultivar selection for organic farmers ? A comparison of European approaches. Organic Eprints
Warlop, Francois; Timmermans, B.G.H.; Brouwer, Gerjan; Nybom, Hilde; LATEUR, MARC; Kelderer, Markus; Weibel, Franco; Lindhard Pedersen, Hanne; GARCIN, Alain; Haug, Philipp; DAPENA, ENRIQUE.
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,...

Nutzbarmachung von Resistenzquellen gegen Flugbrand zur Verbesserung der Immunität in Sommergerste für den ökologischen Landbau Organic Eprints
Sommergerste ist im ökologischen Landbau nach Weizen, Hafer und Dinkel die Getreideart mit der höchsten Bedeutung für die verarbeitende Industrie. Voraussetzung für eine stärkere Verbreitung des Sommergerstenanbaus im ökologischen Landbau ist die Bereitstellung geeigneter Sorten. Für die Sommergerste (Braugerste und Futtergerste) sehen Vertreter der Ökolandbau-Beratung einen hohen Bedarf an Züchtung und Züchtungsforschung (Arbeitskreis Brot- und Braugetreidezüchtung im ökologischen Landbau der LfL, V.Ö.P, n.p.). Resistente Sorten haben im Ökolandbau besonders große Bedeutung. Insbesondere samenübertragbare Krankheiten wie der Gerstenflugbrand sind äußerst schwierig zu kontrollieren und stellen aufgrund ihrer Bedeutung für die Saatguterzeugung ein großes...

Virulence pattern in Danish races of common bunt (Tilletia caries) Common Bunt Organic Eprints
Borgen, Anders.
Spores of common bunt (Tilletia caries) was sampled from different places in Denmark in 2000-2005 and maintained as a bulk sample on susceptible varieties. In 2011 and 2012, spores were harvested from selected infected varieties, and used to reinoculate the same variety from where they were harvested. 98 out of 240 tested varietes had an increase of infection from this inoculation method compared with infection from the bulk spore sample. This is interpreted as a sign of virulence development. Using this method on the differential varieties for bunt resistance and other varieties with known bunt resistance genes indicated that virulence races were present able to infect varieties having resistance genes Bt-1, Bt-2, Bt-3, Bt-4 Bt-5, Bt-7, Bt-8, Bt-10 and...
