20.500.12556/RUL-103602 Vpliv pripravkov Plantonic in Vitisan na višinski prirastek dobovih sejank in okuženost s hrastovo pepelovko (Erysiphe alphitoides) Impact of products plantonic and vitisan on height growth of pendunculate oak seedlings and infection with powdery mildew (Erysiphe alphitoides) Okuženost hrastovih semenk s hrastovo pepelovko (Erysiphe alphitodides Griffon & Maubl.) postaja vse večji problem predvsem pri pomlajevanju dobovih in gradnovih sestojev pri nas in po svetu. V diplomski nalogi smo preizkušali uspešnost dveh pripravkov (Vitisan in Plantonic) za kontrolo hrastove pepelovke. V Krakovskem gozdu smo postavili 20 poskusnih ploskev: 5 kontrolnih, 5 ploskev, ki smo jih škropili z Vitisanom, 5 s Plantonicom in 5 z obema sredstvoma. Na ploskvah smo naključno izbrali po 40 semenk in jim po končanem škropljenju dvakrat ocenili poškodovanost listne ploskve in izmerili višino semenk, da smo dobili višinski prirastek. Meritve smo primerjali med seboj in ugotovili, da obstajajo statistično značilne razlike v stopnji okuženosti listnih ploskev in v relativnem višinskem prirastku škropljenih in neškropljenih semenk. Škropljene semenke so bile manj okužene in relativno višje od kontrole. Kot uspešna kombinacija se je pokazala uporaba obeh pripravkov Vitisan in Planonic skupaj. Powdery mildew (Erysiphe alphitodides Griffon & Maubl.) infection has become a big problem. Especially amongst young pedunculate oak and sessile oak trees in Slovenia and around the world. In an attempt to prevent powdery mildew growth, we have experimented with two different sprays (Vitisan and Plantonic) to protect oak trees. We set 20 experimental plots in the Krakovski gozd forest. Five of them were control plots and hence no spray was used. Five were sprayed with Vitisan, five sprayed with Plantonic and five sprayed with both Vitisan and Plantonic. Forty seedlings were randomly selected for evaluation of damage from powdery mildew and the seedlings height was recorded. Evaluating our results showed that there were statistically significant differences in the level of infection on the leaf surface and in the relative height increment of sprayed and unsprayed seedlings. Sprayed seedilings were less infected and relatively higher than control. The use of both Vitisan and Planonic preparations together proved to be a successful combination. hrastova pepelovka okuženost hrast Vitisan Plantonic fungicid fitofarmacevtsko sredstvo odpornost zdravje bolezen powdery mildew infection oak Vitisan Plantonic fungicide plant protection product resistance health infection true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-09-20 07:46:13 2018-09-20 07:46:15 2022-08-16 03:43:08 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 157258 5188774 4047.pdf 4047.pdf 1 3AD72A28BD42AFABB006663DCAF00C39 99c7f33c64dee3d30fb8b5f363d3d43ea40e10f65e466e9ba60f7a3c71f447a6 da3477d1-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=114053 Biotehniška fakulteta 0 0 0
