20.500.12556/DKUM-82229 Možnosti uporabe vodikovega peroksida za zatiranje škodljivih organizmov v nasadu jablan in trte magistrsko delo Usage Possibilities of Hydrogen Peroxide for Controlling Pests and Diseases in Apple Orchards and Vineyards V vseh državah Evropske unije imamo veliko željo po zmanjšanju rabe klasičnih kemičnih fitofarmacevtskih sredstev (FFS). Zmanjšanje je med drugim možno doseči tudi s povečano rabo alternativnih pripravkov, kamor uvrščamo tudi pripravke na podlagi vodikovega peroksida (H2O2 VP). V rastni sezoni 2020 in 2021 smo na poskusnem posestvu Fakultete za kmetijstvo in biosistemske vede ter na Univerzitetnem centru za vinogradništvo in vinarstvo Meranovo izvedli poljske poskuse v nasadu jablan in trte, da bi ovrednotili potencial nekaterih pripravkov na podlagi VP za zatiranje nekaterih škodljivih organizmov v drugem delu rastne sezone pred obiranjem. Dodatno smo želeli oceniti možnost uporabe VP na pojav skladiščnih bolezni. Rezultati poskusov kažejo, da ponavljajoče uporabe VP v odmerku 500 litrov škropilne brozge na ha pri koncentraciji vsaj 500 ppm v zaključnem obdobju rastne sezone omogočajo zvišanje učinkovitosti zatiranja nekaterih patogenih organizmov. Na testiranih sortah koncentracija škropilne brozge z VP do 500 ppm ni povzročila pojavov fitotoksičnosti, ki bi bili gospodarsko pomembni. Uporaba VP je pokazala zmeren učinek pri poskusu zmanjšanja skladiščnih bolezni na jabolkih. Uporaba VP na vinski trti ni imela vpliva na količino skupnih titracijskih kislin ter topne suhe snovi v grozdju ob obiranju. Rezultati kažejo velik potencial pri uporabi pripravkov na podlagi VP na področju varstva rastlin. All European Union countries manifest a strong desire to reduce the use of conventional chemical plant protection products (PPPs), i.e. phytopharmaceuticals. The above mentioned reduction could be achieved by, among other methods, an increased application of alternative products, including hydrogen peroxide-based preparations (H2O2 HP). In the 2020 and 2021 growing seasons, field trials were carried out in apple and vine plantations at the experimental farm of the Faculty of Agriculture and Life Sciences and at the University Centre of Viticulture and Enology Meranovo, with the aim to evaluate the potential of selected HP-based products for controling of a specific lines of pests in the second part of the growing season, before harvesting. Moreover, our additional goal was to assess the potential usage of HPs in the control of storage diseases. The results of our trials show that repeated applications of HP at a rate of 500 litres of spray at a concentration of at least 500 ppm per ha during the final period of the growing season enable an increased efficiency in controlling certain pathogens. The concentrations of HP spray at up to 500 ppm did not cause to phytotoxicity level of economic significance in the tested varieties. The use of HP showed a moderate effect in an attempt to reduce storage diseases on apples. The application of HP on vines had no effect on the amount of total titratable acids and soluble solids in the grapes at harvest. All in all, the field trial results point to significant potential for applying HP-based products in the domain of plant protection. vodikov peroksid škodljivi organizmi jabolka fitotoksičnost vinska trta hydrogen peroxide pathogens apples phytotoxicity grapevine true true false [F.
