20.500.12556/DKUM-81430 Uspešnost zatiranja glivičnih bolezni pšenice brez triazolskih fungicidov magistrsko delo Efficacy control of fungal diseases in wheat without triazole fungicides V letih 2018 in 2019 smo izvedli dva poljska poskusa, da bi preverili učinkovitost alternativnih fungicidnih škropilnih programov v primerjavi s triazolskimi fungicidnimi programi za zatiranje glivičnih bolezni pšenice (Triticum aestivum L.) sorte 'Illico'. Leta 2019 so bili za primerjavo med škropilne programe vključeni tudi biostimulatorji. Spremljali smo učinkovitost zatiranja pšenične rje (Puccinia triticina), pšenične listne pegavosti (Septoria tritici), žitne pepelovke (Blumeria graminis) in fuzarioze žit (Fusarium sp.). Analizirali smo tudi količino pridelka in kakovostne parametre zrnja. Ugotovili smo, da so imeli škropilni programi z aktivnimi snovmi iz skupine triazolov višje učinkovitosti za zatiranje proučevanih bolezni v primerjavi s programi brez triazolov. Razlike so bile sicer majhne in statistično neznačilne. Večje razlike pa so se pokazale v količini pridelka. V sezoni 2018 so imeli programi s triazoli v povprečju za 100 kg/ha višji pridelek zrnja, medtem ko se je razlika v letu 2019 gibala okoli 900 kg/ha. Tudi v tem primeru so statistično značilne razlike nastale le pri obravnavanjih, za katera vemo, da imajo nizko učinkovitost, ker so bili sestavljeni iz pripravkov, ki niso klasični fungicidi. Razlike med kakovostnimi parametri so bile v obeh sezonah minimalne, kar kaže na to, da škropilni programi niso imeli velikega vpliva na kakovost pšeničnega zrnja. In 2018 and 2019, two field trials were conducted to assess the effectiveness of alternative fungicide spray programmes for controlling fungal diseases in the wheat (Triticum aestivum L.) variety 'Illico' compared to triazole fungicide treatments. In 2019, we included the programe based on biostimulators to compare them with standard fungicides. We monitored the effectiveness of programes for controlling wheat rust (Puccinia triticina), wheat leaf spot diseases (Septoria tritici), cereal powdery mildew (Blumeria graminis) and fusarium head blight of cereals (Fusarium sp.). Besides that, we studied the impact of spray programmes on yield quantity and grain quality parameters. Due to specific weather conditions in individual years, the impact of programes on disease development and programme effectiveness was different. We found out that spray programmes with active substances from the triazole group had better efficacies for the studied diseases control, compared to the ones without triazoles. Yet, the differences were small and statistically insignificant. However, there was a notable difference in the yield: in 2018, triazole programmes gave about 100 kg/ha higher grain yield, while in 2019 the difference was around 900 kg /ha. Still, statistically significant differences arose only in the treatments, which we know to have low efficacy because they were composed of mixtures of substances not belonging to conventional fungicides. The differences between quality parameters were minimal in both seasons, indicating that spray programmes did not have a large impact on the quality of wheat grain. fungicidi triazoli učinkovitost pšenica bolezni fungicides triazoles efficacy wheat diseases true true false [N.
