Abstract

V letih 2017 in 2018 smo na raziskovalni postaji Meranovo (Prinčev vrh) FKBV UM na vinski trti sorte 'Sivi pinot' izvajali poskuse z biostimulatorji Epin extra®, Cirkon® in Siliplant® ter preverjali njihov vpliv na glive povzročiteljice peronospore vinske trte (Plasmopara viticolaBerl., & de Toni), pepelovke vinske trte (Uncinula necator Burr.) in sive grozdne plesni (Botryotinia fuckeliana Fuck.). Preizkušali smo njihovo samostojno učinkovitost ter učinkovitost v kombinaciji s stoodstotnim odmerkom fitofarmacevtskih sredstev (FFS) ali sedemdesetodstotnim odmerkom FFS. Stopnjo okužbe smo ocenjevali po standardni vizualni metodi z opazovanjem napadene površine listja in grozdja. Učinkovitost škropilnih programov smo računali po standardni Abbotovi formuli, ki upošteva razmerje med stopnjo napada pri škropljenih in neškropljenih variantah. Rezultati kažejo, da dodajanje testiranih biostimulatorjev fitofarmacevtskim sredstvom lahko poveča učinkovitost le teh pri zatiranju preučevanih bolezni. Testirani biostimulatorji pa samostojno niso primerni za zatiranje, saj je njihova učinkovitost v primeru močnega napada bolezni premajhna. Njihov učinek je viden tudi na količini pridelka, le-ta se je povečala pri varianti, kjer smo jih dodali stoodstotnemu odmerku FFS.

Secondary title: Biostimulant Effects on Grapevine Disease Control
Secondary abstract: In the years 2017 and 2018 an experiment with biostimulants Epin extra®, Cirkon® and Siliplant® on the 'Pinot gris' vine was conducted at the experimental station Meranovo FKBV UM. Their effect on downy mildew(Plasmopara viticola Berl., & de Toni), powdery mildew(Uncinula necator Burr.) and grey mould (Botryotinia fuckeliana Fuck.) control was examined. The effectiveness of biostimulants for disease control when applied alone and also their effectiveness when combinated with a 100-% dosage of pesticides or 70-% dosage of pesticides was tested. The degree of fungal infection was evaluated with the standard visual method by observing the degree of infected surface of leaves and grapes. We calculated the efficiency of spraying programs via the standard Abbot formula, which includes the ratio between the degree of effected leaf of berrey tissue in sprayed or non sprayed variants. The results show that biostimulants, as an addition to pesticides, can increase the pesticide effectiveness, but are not suitabe for disease control when applied alone without the pesticides, because their efficiency in conditions of high disease presure is too low. Their efficiency is also measurable on grape yield which has increased when the biostimulants were added to the variant, where 100-% doses of pesticides were applied.
