Description of project VineMan.org Project aimed at designing, developing, and testing innovative cropping systems for organic vineyards in Europe for enhancing organic grape production by integrating plant resistance against pathogens, cropping practices, use of weather-driven disease models and biocontrol agents. During the project, 85 substances were tested for their ability to trigger plant innate immunity against pathogenic fungi and oomycetes. Eleven substances reduced downy mildew sporulation and one substance achieved promising results also in field experiments. Methods for manipulating vegetative growth, canopy density, and fruit exposure were evaluated for their ability to create unfavourable microclimates to pathogens and grape favourable conditions. Early leaf removal was effective in reducing bunch sensitivity to grey mould by reducing bunch compactness and increasing berry skin thickness. Mechanistic, weather-driven models for downy and powdery mildews were implemented in a web-based platform able to produce decision-aids for crop protection in organic viticulture. Fitness and efficacy of registered biocontrol agents were evaluated in relation to grape pest and disease control under organic practices. Strain-specific detection systems were developed and tested in controlled and natural conditions. Two innovative management strategies were designed, evaluated through an ex-ante assessment, and tested in vineyards in Italy, Austria, Germany and Slovenia. A risk-adverse strategy was combined fall treatments with the hyperparasite Ampelomyces spp. against overwintering chasmothecia of Erysiphe necator, model predicted schedules for copper and sulphur treatments at label dose and use of a biological control agent against grey mold. A risk-seeking strategy was based on model predicted schedules for copper and sulphur treatments at a low dose and early leaf removal for the control of grey mould. The use of epidemiological models allowed a significant reduction of fungicides, with a consequent reduction of disease management costs and ecotoxicity riskss, and an increased social acceptability of the vineyard management. Applied methods could not detect a significant effect of the applied strategies on the diversity of fungi. Culture dependent studies resulted in a culture collection of partly undescribed species that present an important resource for future studies.

Uporaba piškotkov na naši spletni strani

Pravna podlaga

Podlaga za obvestilo je spremenjeni Zakon o elektronskih komunikacijah (Uradni list št. 109/2012; v nadaljevanju ZEKom-1), ki je začel veljati v začetku leta 2013. Prinesel je nova pravila glede uporabe piškotkov in podobnih tehnologij za shranjevanje informacij ali dostop do informacij, shranjenih na računalniku ali mobilni napravi uporabnika.

Kaj so piškotki?

Piškotki so majhne datoteke, pomembne za delovanje spletnih strani, največkrat z namenom, da je uporabnikova izkušnja boljša.

Piškotek običajno vsebuje zaporedje črk in številk, ki se naloži na uporabnikov računalnik, ko ta obišče določeno spletno stran. Ob vsakem ponovnem obisku bo spletna stran pridobila podatek o naloženem piškotku in uporabnika prepoznala.

Poleg funkcije izboljšanja uporabniške izkušnje je njihov namen različen. Piškotki se lahko uporabljajo tudi za analizo vedenja ali prepoznavanje uporabnikov. Zato ločimo različne vrste piškotkov.

Vrste piškotkov, ki jih uporabljamo na tej spletni strani

Piškotki, ki jih uporabljamo na tej strani sledijo smernicam:

1. Nujno potrebni piškotki

Tovrstni piškotki omogočajo uporabo nujno potrebnih komponent za pravilno delovanje spletne strani. Brez teh piškotov servisi, ki jih želite uporabljati na tej spletni strani, ne bi delovali pravilno (npr. prijava, nakupni proces, ...).

2. Izkustveni piškotki

Tovrstni piškotki zbirajo podatke, kako se uporabniki vedejo na spletni strani z namenom izboljšanja izkustvene komponente spletne strani (npr. katere dele spletne strani obiskujejo najpogosteje). Ti piškotki ne zbirajo informacij, preko katerih bi lahko identificirali uporabnika.

3. Funkcionalni piškotki

Tovrstni piškotki omogočajo spletni strani, da si zapomni nekatere vaše nastavitve in izbire (npr. uporabniško ime, jezik, regijo) in zagotavlja napredne, personalizirane funkcije. Tovrstni piškotki lahko omogočajo sledenje vašim akcijam na spletni strani.

4. Oglasni ali ciljani piškotki

Tovrstne piškotke najpogosteje uporabljajo oglaševalska in družabna omrežja (tretje strani) z namenom, da vam prikažejo bolj ciljane oglase, omejujejo ponavljanje oglasov ali merijo učinkovitost oglaševalskih akcij. Tovrstni piškotki lahko omogočajo sledenje vašim akcijam na spletu.

Nadzor piškotkov

Za uporabo piškotkov se odločate sami. Piškotke lahko vedno odstranite in s tem odstranite vašo prepoznavnost na spletu. Prav tako večino brskalnikov lahko nastavite tako, da piškotkov ne shranjujejo.

Za informacije o možnostih posameznih brskalnikov predlagamo, da si ogledate nastavitve.
