Le mildiou du basilic

Le mildiou du basilic (Peronospora belbahrii) a été identifié en Suisse pour la première fois en 2001, et depuis il rend la vie dure à tous ceux qui aimeraient produire des plantes aromatiques

Falscher Mehltau bei Basilikum

Der Falsche Mehltau bei Basilikum wurde 2001 das erste Mal in der Schweiz entdeckt. Seither macht er allen das Leben schwer, die Kräuter produzieren möchten. Das FiBL Schweiz forscht seit 2018 an praxistauglichen Lösungen gegen den Befall

De l’air chaud autour des feuilles pour contrer le mildiou du basilic

Depuis quelques années, le mildiou du basilic rend la vie difficile aux producteurs d’herbes aromatiques. De nouvelles mesures permettent de contrôler la maladie, qui apparaît surtout à la fin de l’été et en automne

Schwieriger Quereinstieg

Gemüseanbauende Kleinstbetriebe gibt es in der Schweiz bereits seit Jahrzehnten, doch neuerdings rücken sie mehr und mehr in den Fokus. Nun gilt es, institutionelle Schwierigkeiten zu überwinden, damit sich diese Betriebsform noch besser etablieren kann

Blattfleckenkrankheit (Septoria) bei Sellerie

Der Pilz Septoria apiicola ist der wohl bedeutendste Schaderreger im Sellerieanbau. Er verursacht die Blattfleckenkrankheit und kann für Produzentinnen und Produzenten zu erheblichen Ertragseinbussen führen. Vorbeugende Massnahmen und regelmässige Kontrollen lohnen sich

La récolte des semences de tomates

Deux rythmes de récolte de tomate pour la production de semences ont été testés. La récolte peut se faire régulièrement, ou toutes les 2-3 semaines sans influencer la qualité des semences. Les fruits issus de récoltes régulières peuvent être stockés au froid en attendant une extraction groupée

Effects of fruit cooling, picking frequency and time of harvest on seed quality of eight varieties in organic tomato seed production

Seed production of eight tomato genotypes was investigated using two different harvest treatments:regularly (twice a week)or only every three weeks. Seeds were extracted at three different time points. Harvest of tomato fruits for seed production can be done regularly-also alongside a production for fruits, or can be done every three weeks and extracted after exclusion of fruits bearing disease symptoms. Regular picking of fruits slightly enhances fruit yield and therefore seed yield. Fruits can be cool-stored for a pooled extraction-and less work-without negative impact on germination rate.Seeds harvested early in the season tend to have a lower germination rate

Strategies to produce tomato seeds during regular tomato harvest

Tomato production can be time consuming especially when it is done to produce and keep small amounts of seeds. In a trial conducted over two seasons at FiBL, CH, two harvest regimes were tested on 8 tomato genotypes. One regime consisted of a regular harvest of fruits twice a week followed by seed extraction, while the other consisted of a harvest of fruits every three weeks for seed extraction. The main difference between the fruits from the two regimes is their stage of maturity i.e. all fruits are at the optimal stage for consumption with the frequent harvest while fruits are at various maturity stage – from optimal to overripe – with the less frequent harvest. Seeds were also extracted from fruits regularly harvested and stored in a cool chamber (ca. 7°C) for up to 4 weeks prior to extraction. Using fruits from irregular harvest including overripe fruits did not negatively affect seed viability and seed production /Kg fruit. However, fruits or part of fruits with clear disease symptoms should be removed prior to seed extraction. Plants frequently harvested produced a higher fruit yield than those harvested every three weeks which indirectly increased the seed yield. Cooling of the fruits had no impact on seed production and viability. A way to save on time, space and resources while enhancing production, is thus to pool fruits from several regular harvests and store them in a cool room until the quantity is enough for the seed extraction. This also allows to have a small side production of seeds in parallel to the regular production of fruits. In cultivations aimed only at seed production, a less frequent harvest procures a large quantity of fruits at once for the extraction and have no negative impact on seeds

Transfer mulch in organic greenhouses

In organic greenhouses, crop rotations are generally intense and lack diversity, green fallows are rare, and production relies heavily on external inputs. Consequently, problems like soil salinity, nutrient imbalances and crop damage from pest and disease are common. In the Greenresilient project the use of transfer mulch is applied as an ‘innovative’ method and is tested and analysed to determine whether the practice is beneficial for soil health and biodiversity. This leaflet explains the benefits, risks and challenges of transfer mulch, and provides recommendations for practical application

LLM-based Translation Across 500 Years. The Case for Early New High German

The recently developed large language models (LLMs) show surprising translation capabilities for modern languages. In contrast, this paper investigates the ability of GPT-4 and Gemini to translate 500-year-old letters from Early New High German into modern German. We experiment with a corpus from the 16th century that is partly in Latin and partly in ENH-German. This corpus consists of more than 3000 letters that have been edited and annotated by experts from the Institute of Swiss Reformation Studies. We exploit their annotations for the evaluation of machine translation from ENH-German to German. Our experiments show that using the lexical footnotes by the editors in the prompts or directly injected into the text leads to high quality translations
