20.500.12556/DKUM-88405 Preharvest treatments with low-risk plant protection products can help apple growers fulfill the demands of supermarket chains regarding pesticide residues and marketing apples under 0-residue brands As a result of worried consumer pressure, European supermarket chains (ESC) have developed very strict rules about the number and concentration of pesticide active substance residues (AS) accepted in fruits. So-called fruit quality toxicological burden indicators were developed. If fruit suppliers do not comply with ESC requirements, their fruit is often rejected. It is becoming increasingly difficult for apple producers to meet all the requirements of the ESC, so they need new residue reduction tools. One of the options to lower the concentrations of residue on apples is a preharvest application of low-risk preparations (LRP) based on potassium bicarbonate (KHCO3) = PBC, coconut di-ethanol amide ((CH3(CH2)nC(=O)N(CH2CH2OH)2) = DEA, hydrogen peroxide (H2O2) = HP, and a mixture of microbes (EM) that have the ability to dissolve or disintegrate the AS residue. Trials were carried out to test the concept mentioned above. The application of LRP during the last four weeks of preharvest significantly reduced the residue concentration of pesticide AS in apples. Reduction rates among 25 active substances ranged from 0 to 100%, depending on the combination of LRP and AS. HP had the highest capacity to accelerate AS degradation, PB was the second most efficient, and DEA and EM displayed a low residue disintegration ability. The application of the tested LRP can enable apple growers to produce fruits with significantly lower residue concentrations and allows them to comply more successfully with strict ESC rules based on the calculations of toxicological burden indicators. hydrogen peroxide potassium bicarbonate effective microbes detergent pesticide residues fruit marketing rules vodikov peroksid kalijev bikarbonat učinkoviti mikrobi detergent ostanki pesticidov pravila trženja sadja true false true MDPI Angleški jezik Slovenski jezik Znanstveno delo 2024-04-19 13:45:54 2024-04-19 14:02:54 2024-04-20 03:28:44 0000-00-00 00:00:00 2023 0 0 Str. 1-18 Št. 4 Letn. 13, št. članka 1151 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-03-07 2023-04-16 2023-04-18 634.11.632.9 149685507 10.3390/agronomy13041151 2073-4395 Pausic-2023-Preharvest_Treatments_with_Low-Ris.pdf Pausic-2023-Preharvest_Treatments_with_Low-Ris.pdf 1 C82098FAF1A29CBC3B5835B0142D9112 27ac1a1a5c02a51ba9509b3fc861d886071e472c1b7abb202302352db2580dd0 513d7268-fe43-11ee-8dad-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=178781 https://doi.org/10.3390/agronomy13041151 0 61e10d26-fe42-11ee-8dad-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=178780 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
