20.500.12556/DKUM-63799 Primerjava učinkovitosti integriranega in ekološkega škropilnega programa na uspešnost zatiranja bolezni in škodljivcev čebule (Allium cepa L. cv. Ptujski rdeči) Comparison of effectivnes of integrated and organic spray programes for diseases and pest control of onion (Allium cepa L. cv. Ptujski rdeči) Z namenom primerjanja učinkovitosti zatiranja škodljivcev in bolezni pri dveh škropilnih programih (7 aplikacij pripravkov letno) je bil izveden poljski poskus v nasadu čebule cv. Ptujski rdeči. Preučevali smo naslednje škodljive organizme (PseudoPseudoperonospora destructor, Stemphyllium vesicarium, Alternaria porii and Thrips tabaci). Integriran škropilni program (INT) je temeljil na uporabi naslednjih aktivnih snovi pripravkov: Cu-hidroksid, azoksistrobin, mankozeb, metalaksil, ciprodinil, fludioksonil, dimetoat in sintetični piretroidi. Alternativni ekološki škropilni program (EKO) je temeljil na uporabi pripravkov na podlagi izločkov alg (Frutogard), Cu-glukonata (Labicuper), Cu-hidroksida, Bacillus subtilis (Serenade), kisle gline (Ulmasud), izločkov rastline Reynoutria sachalinensis (Milsana) in naravnih piretrinov. INT program je zagotovil značilno višjo učinkovitost zatiranja vseh preučevanih škodljivih organizmov. Kljub nižji stopnji zatiranja škodljivih organizmov pri EKO programu, ugotovljen pridelek na EKO parcelicah ni bil statistično značilno nižji od tistega na INT parcelicah. Škropljenja smo izvajali s tremi različnimi tipi šob (TeeJet Twin, TeeJet XR, TeeJet Turbo Twin). Pri INT programu so šobe imele značilen vpliv na učinkovitost pripravkov, med tem ko pri EKO programu šobe niso imele značilnega vpliva na učinkovitost pripravkov. Field trial was carried out to compare effectiveness of control of pests and diseases of onion cv. Ptujski rdeči with two spray programs (7 applications a season). The fallowing harmful organisms (HO) were studied (Pseudoperonospora destructor, Stemphyllium vesicarium, Alternaria porii and Thrips tabaci). Integrated spray program (INT) was based on use of following active substances Cu-hydroxide, azoxystrobene, mancozeb, metalaxyl, cyprodinil, fludioxonyl, dimetoate and synthetic piretrines. Alternative spray organic program (ORG) was based on use of algae extracts (Frutogard), Cu-gluconate (Labicuper), Cu-hydroxide, Bacillus subtilis (Serenade), acid clay (Ulmasud), Reynoutria sachalinensis extract (Milsana), and natural piretrines. INT program provided significantly higher control rate of all studied HO. Despite the lover rate of efficacy of HO control at ORG plots the established yield of ORG plots was not significantly lower in comparison to that established on INT plots. Sprays were applied with three different nozzles (TeeJet Twin, TeeJet XR, TeeJet Turbo Twin). At INT nozzles had significant impact on the product efficacy, on other had they didn’t influence significantly the efficacy of products applied at ORG spray program. čebula bolezni škodljivci zatiranje šobe ekološka in integrirana pridelava onion disease pest control nozzles organic integrated true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-09-16 08:48:18 2016-10-12 07:10:25 2022-07-03 03:07:02 2019-07-11 13:40:15 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:LTSZTBF1 VS_Ilersic_Ema_2016.pdf VS_Ilersic_Ema_2016.pdf 1 A9194277277E8CAADD92DE271B22E618 bdfa36060e17fc2462f98d066511b1173a39848b2e145449fee95fe4794fa194 a7769cdb-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=106406 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
