20.500.12556/RUL-182374 Učinkovitost zatiranja verticilijske uvelosti (Verticillium dahliae) na papriki z biotičnim pripravkom na podlagi bakterije Bacillus amyloliquefaciens Efficacy management of verticillium wilt (Verticillium dahliae) in peppers with a biotic preparation based on the bacteria Bacillus amyloliquefaciens Bolezni, ki jih povzročajo glivični in bakterijski patogeni, ki se prenašajo s tlemi, predstavljajo skupino pomembnih rastlinskih bolezni, ki omejujejo pridelavo po vsem svetu. Verticilijska uvelost je ena najpogostejših bolezni, ki tako v Sloveniji kot drugod po svetu povzroča velike izgube pridelka. Patogen vstopi v rastlino skozi korenine vse do ksilema, kjer zamaši prevodni sistem in s tem povzroči uvelost rastline in posledično manjši pridelek. Da se pojavu bolezni izognemo, je priporočeno kolobarjenje, uporaba odpornih sort ali cepljenje na odporne podlage ter uporaba fungicidov. Ker ima ekološko kmetovanje vse večji pomen, uporaba sintetičnih fungicidov pa ni dovoljena, so vse večjega pomena biotični pripravki na osnovi gliv in bakterij. Serenade ASO je biotični pripravek na osnovi bakterije Bacillus amyloliquefaciens, ki preprečuje rast povzročiteljev bolezni na način, da z njimi tekmuje za življenjski prostor in hrano. Glavni namen poskusa je bil preučiti vpliv biotičnega pripravka Serenade ASO na pojav okužbe z verticilijsko uvelostjo (Verticillium dahliae) na izbrani sorti paprike 'Blondy F1' in njegova potencialna razširitev registracije, saj v Sloveniji ni registriran za varstvo proti verticilijski uvelosti. Rezultati niso pokazali bistvenih razlik med obravnavanji, poleg tega so bile izredno neugodne vremenske razmere s točo, obilnim dežjem in vetrom. Na njivi je bila opažena boljša rast v predelih, kjer ni zastajala voda, vendar ti predeli niso bili enakomerno razporejeni med bloki. Diseases caused by fungal and bacterial pathogens transmitted through the soil are group of significant plant diseases that limit crop production worldwide. Verticillium wilt is one of the most common diseases, causing substantial yield losses both in Slovenia and globally. The pathogen enters the plant through the roots and reaches the xylem, where blocking the vascular system, causes the plant wilting and consequently reduced yield. To prevent the occurrence of the disease, crop rotation, the use of resistant varieties or grafting onto resistant rootstocks, and the application of fungicides are recommended. As organic farming gains increasing importance and the use of synthetic fungicides is not permitted, biotic preparations based on fungi and bacteria are becoming increasingly significant. Serenade ASO is a biotic preparation based on the bacterium Bacillus amyloliquefaciens, which prevents the growth of pathogens by competing with them for living space and nutrients. The main objective of the experiment was to examine the effect of the biotic preparation Serenade ASO on the occurrence of Verticillium wilt (Verticillium dahliae) infection in the selected pepper variety 'Blondy F1' and its potential extension of registration, as it is not registered in Slovenia for protection against Verticillium wilt. The results did not show significant differences. Moreover, extreme weather conditions, including hail, heavy rainfall, and strong winds, negatively affected the experiment. Better plant growth was observed in areas where water did not accumulate, but these areas were not evenly distributed among the blocks. verticilijska uvelost bakterijski antagonist Bacillus amyloliquefaciens biotični pripravek verticillium wilt bacterial antagonist Bacillus amyloliquefaciens biotic preparation true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-05-08 12:38:28 2026-05-08 12:38:38 2026-05-15 12:57:36 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 279481 277753603 56230.pdf 56230.pdf 1 FBACF40CE20CAD6E6B982ADCD5C776BC b6151a56cfabea3c66a62181b59b89334c9548e78f30c58965d7ecc80e59dbe6 c74144e9-4ac9-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=233567 Biotehniška fakulteta 0 0 0
