20.500.12556/DKUM-17017 VPLIV FORMULACIJE BAKROVIH PRIPRAVKOV NA STOPNJO UČINKOVITOSTI ZATIRANJA JABLANOVEGA ŠKRLUPA Venturia inaequalis (Cooke) Wint. Influence of formulations of copper preparations on their efficacy for apple scab (Venturia inaequalis (Cooke) Wint.) control V letu 2009 je bil na poskusni postaji Fakultete za kmetijstvo in biosistemske vede v Hočah pri Mariboru izveden poljski poskus, v katerem smo preučevali vpliv različnih bakrovih formulacij (fungicidov in listnih gnojil) na stopnjo učinkovitosti zatiranja jablanovega škrlupa Venturia inaequalis (Cooke) Wint pri 7. sortah jablan (Zlati delišes, Gala, Fuji, Idared, Breaburn, Jonagold in Elstar). Pripravki na podlagi različnih kemičnih oblik bakra so bili uporabljeni v času cvetenja jablan in po njem 14-krat, vsakič v odmerku 200 g Cu++/ha. V poskusu smo imeli pripravke na podlagi snovi Cu-Ca-oksiklorid (standard poskusa), bakrovega sulfata in kompleksov bakra s peptidi, EDTA, sečnino in glukonsko kislino z delnim sistemičnim delovanjem. Poskusne formulacije delno sistemično delujočih listnih gnojil so imele skoraj enak nivo učinkovitosti zatiranja jablanovega škrlupa na listju (63-94 %) in plodovih (74-98 %) kot standardni pripravek na podlagi Cu-Ca-oksiklorida (60-85 % in 72-95 %). Pri zatiranju škrlupa na listju so sistemično delujoči pripravki pri več sortah jablan dali značilno boljše rezultate kot standardna formulacija. Dosežena stopnja učinkovitosti poskusnih formulacij je bila pri različnih sortah jablan značilno različna. A trial was carried out in 2009 on apple plantation of Faculty of Agriculture and Life Sciences in Hoče in Maribor in order to determine influence of formulations of copper preparations (fungicides and foliar fertilizers) on the level of control of apple scab Venturia inaequalis (Cooke) Wint. Preparations were applied during the apple blooming and afterwards, totally 14 times, at rate of 200 g Cu++/ha to 7 different apple cultivars (Golden Delicious, Gala, Fuji, Idared, Breaburn, Jonagold and Elstar). The applied formulations were based on Cu-Ca-oxychloride (trial standard), copper sulphate, and complexes or chelates of copper with peptides, EDTA, urea and gluconic acid. The achieved level of efficiency for control of apple scab on leaves (63-94 %) and fruits (74-98 %) of experimental copper formulations with partial systemic activity was almost equal to that of standard copper fungicide based on Cu-Ca- oxychloride (60-85 % and 72-95 %). In case of control of scab on leaves the performance of systemic formulations was significantly better than in the performance of standard formulation at several apple cultivars. The achieved level of efficacy of different experimental copper formulations was different at different apple cultivars. formulacije bakrovih fungicidov jablana zatiranje škrlup copper fungicide formulations apple sscab control true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-12-13 09:33:28 2011-01-11 10:25:49 2022-04-13 09:07:15 2023-12-21 03:26:36 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:BRPHFJNO UNI_Petrovic_Suzana_2010.pdf UNI_Petrovic_Suzana_2010.pdf 1 E30F1D03DD16819FE5E9C46C4AAB2D14 a54ed0e8f04af84e316d1e8bf5df616f6cf4cb0e8b7fe50c8fae727cae2f7c20 c70dae82-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/dd43f205-d72e-4e67-8e7d-5f797514eda6 https://dk.um.si/Dokument.php?lang=slv&id=19591 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
